    "content": "---\ntitle: Production users\n---\n\nThis document tracks people and use cases for etcd in production. By creating a list of production use cases we hope to build a community of advisors that we can reach out to with experience using various etcd applications, operation environments, and cluster sizes. The etcd development team may reach out periodically to check-in on how etcd is working in the field and update this list.\n\n## All Kubernetes Users\n\n- *Application*: https://kubernetes.io/\n- *Environments*: AWS, OpenStack, Azure, Google Cloud, Huawei Cloud, Bare Metal, etc\n\n**This is a meta user; please feel free to document specific Kubernetes clusters!**\n\nAll Kubernetes clusters use etcd as their primary data store.

Let's assume that a watcher had been requested with a future revision X and sent to node A that became network-partitioned thereafter. Meanwhile, cluster makes progress. Then when the partition gets removed, the leader sends a snapshot to node A. Previously if the snapshot's latest revision is still lower than the watch revision X,  **etcd server panicked** during snapshot restore operation.\n  - Now, this server-side panic has been fixed.\n\n### Go\n\n- Compile with [*Go 1.8.7*](https://golang.org/doc/devel/release.html#go1.8).\n\n\n---\n\n\n## [v3.1.15](https://github.com/etcd-io/etcd/releases/tag/v3.1.15) (2018-05-09)\n\nSee [code changes](https://github.com/etcd-io/etcd/compare/v3.1.14...v3.1.15) and [v3.1 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_1/) for any breaking changes.\n\n**Again, before running upgrades from any previous release, please make sure to read change logs below and [v3.1 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_1/).**\n\n### etcd server\n\n- Purge old [`*.snap.db` snapshot files](https://github.com/etcd-io/etcd/pull/7967).\n  - Previously, etcd did not respect `--max-snapshots` flag to purge old `*.snap.db` files.\n  - Now, etcd purges old `*.snap.db` files to keep maximum `--max-snapshots` number of files on disk.\n\n### Go\n\n- Compile with [*Go 1.8.7*](https://golang.org/doc/devel/release.html#go1.8).\n\n\n---\n\n\n## [v3.1.14](https://github.com/etcd-io/etcd/releases/tag/v3.1.14) (2018-04-24)\n\nSee [code changes](https://github.com/etcd-io/etcd/compare/v3.1.13...v3.1.14) and [v3.1 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_1/) for any breaking changes.\n\n**Again, before running upgrades from any previous release, please make sure to read change logs below and [v3.1 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_1/).**\n\n### Metrics, Monitoring\n\nSee [List of metrics](https://github.com/etcd-io/etcd/tree/main/Documentation/metrics) for all metrics per release.\n\nNote that any `etcd_debugging_*` metrics are experimental and subject to change.\n\n- Add [`etcd_server_is_leader`](https://github.com/etcd-io/etcd/pull/9587) Prometheus metric.\n\n### etcd server\n\n- Add [`--initial-election-tick-advance`](https://github.com/etcd-io/etcd/pull/9591) flag to configure initial election tick fast-forward.\n  - By default, `--initial-election-tick-advance=true`, then local member fast-forwards election ticks to speed up \"initial\" leader election trigger.\n  - This benefits the case of larger election ticks. For instance, cross datacenter deployment may require longer election timeout of 10-second. If true, local node does not need wait up to 10-second. Instead, forwards its election ticks to 8-second, and have only 2-second left before leader election.\n  - Major assumptions are that: cluster has no active leader thus advancing ticks enables faster leader election. Or cluster already has an established leader, and rejoining follower is likely to receive heartbeats from the leader after tick advance and before election timeout.\n  - However, when network from leader to rejoining follower is congested, and the follower does not receive leader heartbeat within left election ticks, disruptive election has to happen thus affecting cluster availabilities.\n  - Now, this can be disabled by setting `--initial-election-tick-advance=false`.\n  - Disabling this would slow down initial bootstrap process for cross datacenter deployments. Make tradeoffs by configuring `--initial-election-tick-advance` at the cost of slow initial bootstrap.\n  - If single-node, it advances ticks regardless.\n  - Address [disruptive rejoining follower node](https://github.com/etcd-io/etcd/issues/9333).\n\n### Go\n\n- Compile with [*Go 1.8.7*](https://golang.org/doc/devel/release.html#go1.8).\n\n\n---\n\n\n## [v3.1.13](https://github.com/etcd-io/etcd/releases/tag/v3.1.13) (2018-03-29)\n\nSee [code changes](https://github.com/etcd-io/etcd/compare/v3.1.12...v3.1.13) and [v3.1 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_1/) for any breaking changes.\n\n**Again, before running upgrades from any previous release, please make sure to read change logs below and [v3.1 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_1/).**\n\n### Improved\n\n- Adjust [election timeout on server restart](https://github.com/etcd-io/etcd/pull/9415) to reduce [disruptive rejoining servers](https://github.com/etcd-io/etcd/issues/9333).\n  - Previously, etcd fast-forwards election ticks on server start, with only one tick left for leader election. This is to speed up start phase, without having to wait until all election ticks elapse. Advancing election ticks is useful for cross datacenter deployments with larger election timeouts. However, it was affecting cluster availability if the last tick elapses before leader contacts the restarted node.\n  - Now, when etcd restarts, it adjusts election ticks with more than one tick left, thus more time for leader to prevent disruptive restart.\n\n### Metrics, Monitoring\n\nSee [List of metrics](https://github.com/etcd-io/etcd/tree/main/Documentation/metrics) for all metrics per release.\n\nNote that any `etcd_debugging_*` metrics are experimental and subject to change.\n\n- Add missing [`etcd_network_peer_sent_failures_total` count](https://github.com/etcd-io/etcd/pull/9437).\n\n### Go\n\n- Compile with [*Go 1.8.7*](https://golang.org/doc/devel/release.html#go1.8).\n\n\n---\n\n\n## [v3.1.12](https://github.com/etcd-io/etcd/releases/tag/v3.1.12) (2018-03-08)\n\nSee [code changes](https://github.com/etcd-io/etcd/compare/v3.1.11...v3.1.12) and [v3.1 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_1/) for any breaking changes.\n\n**Again, before running upgrades from any previous release, please make sure to read change logs below and [v3.1 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_1/).**\n\n### etcd server\n\n- Fix [`mvcc` \"unsynced\" watcher restore operation](https://github.com/etcd-io/etcd/pull/9297).\n  - \"unsynced\" watcher is watcher that needs to be in sync with events that have happened.\n  - That is, \"unsynced\" watcher is the slow watcher that was requested on old revision.\n  - \"unsynced\" watcher restore operation was not correctly populating its underlying watcher group.\n  - Which possibly causes [missing events from \"unsynced\" watchers](https://github.com/etcd-io/etcd/issues/9086).\n  - A node gets network partitioned with a watcher on a future revision, and falls behind receiving a leader snapshot after partition gets removed. When applying this snapshot, etcd watch storage moves current synced watchers to unsynced since sync watchers might have become stale during network partition. And reset synced watcher group to restart watcher routines. Previously, there was a bug when moving from synced watcher group to unsynced, thus client would miss events when the watcher was requested to the network-partitioned node.\n\n### Go\n\n- Compile with

`etcd_grpc_unary_requests_duration_seconds`\n\n### Dependency\n\n- Upgrade [`github.com/ugorji/go/codec`](https://github.com/ugorji/go) to [**`ugorji/go@9c7f9b7`**](https://github.com/ugorji/go/commit/9c7f9b7a2bc3a520f7c7b30b34b7f85f47fe27b6), and [regenerate v2 `client`](https://github.com/etcd-io/etcd/pull/6945).\n\n### Security, Authentication\n\nSee [security doc](https://etcd.io/docs/latest/op-guide/security/) for more details.\n\n- SRV records (e.g., infra1.example.com) must match the discovery domain (i.e., example.com) if no custom certificate authority is given.\n  - `TLSConfig.ServerName` is ignored with user-provided certificates for backwards compatibility; to be deprecated.\n  - For example, `etcd --discovery-srv=example.com` will only authenticate peers/clients when the provided certs have root domain `example.com` as an entry in Subject Alternative Name (SAN) field.\n\n### etcd server\n\n- Automatic leadership transfer when leader steps down.\n- etcd flags\n  - `--strict-reconfig-check` flag is set by default.\n  - Add `--log-output` flag.\n  - Add `--metrics` flag.\n- etcd uses default route IP if advertise URL is not given.\n- Cluster rejects removing members if quorum will be lost.\n- Discovery now has upper limit for waiting on retries.\n- Warn on binding listeners through domain names; to be deprecated.\n- v3.0 and v3.1 with `--auto-compaction-retention=10` run periodic compaction on v3 key-value store for every 10-hour.\n  - Compactor only supports periodic compaction.\n  - Compactor records latest revisions every 5-minute, until it reaches the first compaction period (e.g. 10-hour).\n  - In order to retain key-value history of last compaction period, it uses the last revision that was fetched before compaction period, from the revision records that were collected every 5-minute.\n  - When `--auto-compaction-retention=10`, compactor uses revision 100 for compact revision where revision 100 is the latest revision fetched from 10 hours ago.\n  - If compaction succeeds or requested revision has already been compacted, it resets period timer and starts over with new historical revision records (e.g. restart revision collect and compact for the next 10-hour period).\n  - If compaction fails, it retries in 5 minutes.\n\n### client v3\n\n- Add `SetEndpoints` method; update endpoints at runtime.\n- Add `Sync` method; auto-update endpoints at runtime.\n- Add `Lease TimeToLive` API; fetch lease information.\n- replace Config.Logger field with global logger.\n- Get API responses are sorted in ascending order by default.\n\n### etcdctl v3\n\n- Add `lease timetolive` command.\n- Add `--print-value-only` flag to get command.\n- Add `--dest-prefix` flag to make-mirror command.\n- `get` command responses are sorted in ascending order by default.\n\n### gRPC Proxy\n\n- Experimental gRPC proxy feature.\n\n### Other\n\n- `recipes` now conform to sessions defined in `clientv3/concurrency`.\n- ACI has symlinks to `/usr/local/bin/etcd*`.\n\n### Go\n\n- Compile with [*Go 1.7.4*](https://golang.org/doc/devel/release.html#go1.7).\n\n\n---\n\n"

Let's assume that a watcher had been requested with a future revision X and sent to node A that became network-partitioned thereafter. Meanwhile, cluster makes progress. Then when the partition gets removed, the leader sends a snapshot to node A.

Previously, etcd always populates `(*tls.Config).Certificates` on the initial client TLS handshake, as non-empty. Thus, client was always expected to supply a matching SNI in order to pass the TLS verification and to trigger `(*tls.Config).GetCertificate` to reload TLS assets.\n  - However, a certificate whose SAN field does [not include any domain names but only IP addresses](https://github.com/etcd-io/etcd/issues/9541) would request `*tls.ClientHelloInfo` with an empty `ServerName` field, thus failing to trigger the TLS reload on initial TLS handshake; this becomes a problem when expired certificates need to be replaced online.\n  - Now, `(*tls.Config).Certificates` is created empty on initial TLS client handshake, first to trigger `(*tls.Config).GetCertificate`, and then to populate rest of the certificates on every new TLS connection, even when client SNI is empty (e.g. cert only includes IPs).\n\n### etcd server\n\n- Add [`etcd --initial-election-tick-advance`](https://github.com/etcd-io/etcd/pull/9591) flag to configure initial election tick fast-forward.\n  - By default, `etcd --initial-election-tick-advance=true`, then local member fast-forwards election ticks to speed up \"initial\" leader election trigger.\n  - This benefits the case of larger election ticks. For instance, cross datacenter deployment may require longer election timeout of 10-second. If true, local node does not need wait up to 10-second. Instead, forwards its election ticks to 8-second, and have only 2-second left before leader election.\n  - Major assumptions are that: cluster has no active leader thus advancing ticks enables faster leader election. Or cluster already has an established leader, and rejoining follower is likely to receive heartbeats from the leader after tick advance and before election timeout.\n  - However, when network from leader to rejoining follower is congested, and the follower does not receive leader heartbeat within left election ticks, disruptive election has to happen thus affecting cluster availabilities.\n  - Now, this can be disabled by setting `--initial-election-tick-advance=false`.\n  - Disabling this would slow down initial bootstrap process for cross datacenter deployments. Make tradeoffs by configuring `--initial-election-tick-advance` at the cost of slow initial bootstrap.\n  - If single-node, it advances ticks regardless.\n  - Address [disruptive rejoining follower node](https://github.com/etcd-io/etcd/issues/9333).\n\n### Go\n\n- Compile with [*Go 1.8.7*](https://golang.org/doc/devel/release.html#go1.8).\n\n\n---\n\n\n## [v3.2.18](https://github.com/etcd-io/etcd/releases/tag/v3.2.18) (2018-03-29)\n\nSee [code changes](https://github.com/etcd-io/etcd/compare/v3.2.17...v3.2.18) and [v3.2 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_2/) for any breaking changes.\n\n**Again, before running upgrades from any previous release, please make sure to read change logs below and [v3.2 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_2/).**\n\n### Improved\n\n- Adjust [election timeout on server restart](https://github.com/etcd-io/etcd/pull/9415) to reduce [disruptive rejoining servers](https://github.com/etcd-io/etcd/issues/9333).\n  - Previously, etcd fast-forwards election ticks on server start, with only one tick left for leader election. This is to speed up start phase, without having to wait until all election ticks elapse. Advancing election ticks is useful for cross datacenter deployments with larger election timeouts. However, it was affecting cluster availability if the last tick elapses before leader contacts the restarted node.\n  - Now, when etcd restarts, it adjusts election ticks with more than one tick left, thus more time for leader to prevent disruptive restart.\n\n### Metrics, Monitoring\n\nSee [List of metrics](https://github.com/etcd-io/etcd/tree/main/Documentation/metrics) for all metrics per release.\n\nNote that any `etcd_debugging_*` metrics are experimental and subject to change.\n\n- Add missing [`etcd_network_peer_sent_failures_total` count](https://github.com/etcd-io/etcd/pull/9437).\n\n### Go\n\n- Compile with [*Go 1.8.7*](https://golang.org/doc/devel/release.html#go1.8).\n\n\n---\n\n\n## [v3.2.17](https://github.com/etcd-io/etcd/releases/tag/v3.2.17) (2018-03-08)\n\nSee [code changes](https://github.com/etcd-io/etcd/compare/v3.2.16...v3.2.17) and [v3.2 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_2/) for any breaking changes.\n\n**Again, before running upgrades from any previous release, please make sure to read change logs below and [v3.2 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_2/).**\n\n### etcd server\n\n- Fix [server panic on invalid Election Proclaim/Resign HTTP(S) requests](https://github.com/etcd-io/etcd/pull/9379).\n  - Previously, wrong-formatted HTTP requests to Election API could trigger panic in etcd server.\n  - e.g. `curl -L http://localhost:2379/v3/election/proclaim -X POST -d '{\"value\":\"\"}'`, `curl -L http://localhost:2379/v3/election/resign -X POST -d '{\"value\":\"\"}'`.\n- Prevent [overflow by large `TTL` values for `Lease` `Grant`](https://github.com/etcd-io/etcd/pull/9399).\n  - `TTL` parameter to `Grant` request is unit of second.\n  - Leases with too large `TTL` values exceeding `math.MaxInt64` [expire in unexpected ways](https://github.com/etcd-io/etcd/issues/9374).\n  - Server now returns `rpctypes.ErrLeaseTTLTooLarge` to client, when the requested `TTL` is larger than *9,000,000,000 seconds* (which is >285 years).\n  - Again, etcd `Lease` is meant for short-periodic keepalives or sessions, in the range of seconds or minutes.

When applying this snapshot, etcd watch storage moves current synced watchers to unsynced since sync watchers might have become stale during network partition. And reset synced watcher group to restart watcher routines. Previously, there was a bug when moving from synced watcher group to unsynced, thus client would miss events when the watcher was requested to the network-partitioned node.\n\n### Go\n\n- Compile with [*Go 1.8.5*](https://golang.org/doc/devel/release.html#go1.8).\n\n\n---\n\n\n## [v3.2.15](https://github.com/etcd-io/etcd/releases/tag/v3.2.15) (2018-01-22)\n\nSee [code changes](https://github.com/etcd-io/etcd/compare/v3.2.14...v3.2.15) and [v3.2 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_2/) for any breaking changes.\n\n**Again, before running upgrades from any previous release, please make sure to read change logs below and [v3.2 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_2/).**\n\n### etcd server\n\n- Prevent [server panic from member update/add](https://github.com/etcd-io/etcd/pull/9174) with [wrong scheme URLs](https://github.com/etcd-io/etcd/issues/9173).\n- Log [user context cancel errors on stream APIs in debug level with TLS](https://github.com/etcd-io/etcd/pull/9178).\n\n### Go\n\n- Compile with [*Go 1.8.5*](https://golang.org/doc/devel/release.html#go1.8).\n\n\n---\n\n\n## [v3.2.14](https://github.com/etcd-io/etcd/releases/tag/v3.2.14) (2018-01-11)\n\nSee [code changes](https://github.com/etcd-io/etcd/compare/v3.2.13...v3.2.14) and [v3.2 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_2/) for any breaking changes.\n\n**Again, before running upgrades from any previous release, please make sure to read change logs below and [v3.2 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_2/).**\n\n### Improved\n\n- Log [user context cancel errors on stream APIs in debug level](https://github.com/etcd-io/etcd/pull/9105).\n\n### etcd server\n\n- Fix [`mvcc/backend.defragdb` nil-pointer dereference on create bucket failure](https://github.com/etcd-io/etcd/pull/9119).\n\n### Go\n\n- Compile with [*Go 1.8.5*](https://golang.org/doc/devel/release.html#go1.8).\n\n\n---\n\n\n## [v3.2.13](https://github.com/etcd-io/etcd/releases/tag/v3.2.13) (2018-01-02)\n\nSee [code changes](https://github.com/etcd-io/etcd/compare/v3.2.12...v3.2.13) and [v3.2 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_2/) for any breaking changes.\n\n**Again, before running upgrades from any previous release, please make sure to read change logs below and [v3.2 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_2/).**\n\n### etcd server\n\n- Remove [verbose error messages on stream cancel and gRPC info-level logs](https://github.com/etcd-io/etcd/pull/9080) in server-side.\n- Fix [gRPC server panic on `GracefulStop` TLS-enabled server](https://github.com/etcd-io/etcd/pull/8987).\n\n### Go\n\n- Compile with [*Go 1.8.5*](https://golang.org/doc/devel/release.html#go1.8).\n\n\n---\n\n\n## [v3.2.12](https://github.com/etcd-io/etcd/releases/tag/v3.2.12) (2017-12-20)\n\nSee [code changes](https://github.com/etcd-io/etcd/compare/v3.2.11...v3.2.12) and [v3.2 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_2/) for any breaking changes.\n\n**Again, before running upgrades from any previous release, please make sure to read change logs below and [v3.2 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_2/).**\n\n### Dependency\n\n- Upgrade [`google.golang.org/grpc`](https://github.com/grpc/grpc-go/releases/tag) from [**`v1.7.4`**](https://github.com/grpc/grpc-go/releases/tag/v1.7.4) to [**`v1.7.5`**](https://github.com/grpc/grpc-go/releases/tag/v1.7.5).\n- Upgrade [`github.com/grpc-ecosystem/grpc-gateway`](https://github.com/grpc-ecosystem/grpc-gateway/releases) from [**`v1.3`**](https://github.com/grpc-ecosystem/grpc-gateway/releases/tag/v1.3) to [**`v1.3.0`**](https://github.com/grpc-ecosystem/grpc-gateway/releases/tag/v1.3.0).\n\n### etcd server\n\n- Fix [error message of `Revision` compactor](https://github.com/etcd-io/etcd/pull/8999) in server-side.\n\n### client v3\n\n- Add [`MaxCallSendMsgSize` and `MaxCallRecvMsgSize`](https://github.com/etcd-io/etcd/pull/9047) fields to [`clientv3.Config`](https://godoc.org/github.com/etcd-io/etcd/clientv3#Config).\n  -

For instance, if peer cert contains only DNS names (no IP addresses) in Subject Alternative Name (SAN) field, server first reverse-lookups the remote IP address to get a list of names mapping to that address (e.g. `nslookup IPADDR`). Then accepts the connection if those names have a matching name with peer cert's DNS names (either by exact or wildcard match). If none is matched, server forward-lookups each DNS entry in peer cert (e.g. look up `example.default.svc` when the entry is `*.example.default.svc`), and accepts connection only when the host's resolved addresses have the matching IP address with the peer's remote IP address. For example, peer B's CSR (with `cfssl`) SAN field is `[\"*.example.default.svc\", \"*.example.default.svc.cluster.local\"]` when peer B's remote IP address is `10.138.0.2`. When peer B tries to join the cluster, peer A reverse-lookup the IP `10.138.0.2` to get the list of host names. And either exact or wildcard match the host names with peer B's cert DNS names in Subject Alternative Name (SAN) field. If none of reverse/forward lookups worked, it returns an error `\"tls: \"10.138.0.2\" does not match any of DNSNames [\"*.example.default.svc\",\"*.example.default.svc.cluster.local\"]`.

This is useful when replacing expiry certs without stopping etcd servers; it can be done by overwriting old certs with new ones. Refreshing certs for every connection should not have too much overhead, but can be improved in the future, with caching layer. Example tests can be found [here](https://github.com/etcd-io/etcd/blob/b041ce5d514a4b4aaeefbffb008f0c7570a18986/integration/v3_grpc_test.go#L1601-L1757).\n- [Server denies incoming peer certs with wrong IP `SAN`](https://github.com/etcd-io/etcd/pull/7687). For instance, if peer cert contains any IP addresses in Subject Alternative Name (SAN) field, server authenticates a peer only when the remote IP address matches one of those IP addresses. This is to prevent unauthorized endpoints from joining the cluster.  For example, peer B's CSR (with `cfssl`) SAN field is `[\"*.example.default.svc\", \"*.example.default.svc.cluster.local\", \"10.138.0.27\"]` when peer B's actual IP address is `10.138.0.2`, not `10.138.0.27`. When peer B tries to join the cluster, peer A will reject B with the error `x509: certificate is valid for 10.138.0.27, not 10.138.0.2`, because B's remote IP address does not match the one in Subject Alternative Name (SAN) field.\n- [Server resolves TLS `DNSNames` when checking `SAN`](https://github.com/etcd-io/etcd/pull/7767). For instance, if peer cert contains only DNS names (no IP addresses) in Subject Alternative Name (SAN) field, server authenticates a peer only when forward-lookups (`dig b.com`) on those DNS names have matching IP with the remote IP address.  For example, peer B's CSR (with `cfssl`) SAN field is `[\"b.com\"]` when peer B's remote IP address is `10.138.0.2`. When peer B tries to join the cluster, peer A looks up the incoming host `b.com` to get the list of IP addresses (e.g. `dig b.com`). And rejects B if the list does not contain the IP `10.138.0.2`, with the error `tls: 10.138.0.2 does not match any of DNSNames [\"b.com\"]`.\n- Auth support JWT token.\n\n### etcd server\n\n- RPCs\n  - Add Election, Lock service.\n- Native client `etcdserver/api/v3client`\n  - client \"embedded\" in the server.\n- Logging, monitoring\n  - Server warns large snapshot operations.\n- Add `etcd --enable-v2` flag to enable v2 API server.\n  - `etcd --enable-v2=true` by default.\n- Add `etcd --auth-token` flag.\n- v3.2 compactor runs [every hour](https://github.com/etcd-io/etcd/pull/7875).\n  - Compactor only supports periodic compaction.\n  - Compactor continues to record latest revisions every 5-minute.\n  - For every hour, it uses the last revision that was fetched before compaction period, from the revision records that were collected every 5-minute.\n  - That is, for every hour, compactor discards historical data created before compaction period.\n  - The retention window of compaction period moves to next hour.\n  - For instance, when hourly writes are 100 and `--auto-compaction-retention=10`, v3.1 compacts revision 1000, 2000, and 3000 for every 10-hour, while v3.2 compacts revision 1000, 1100, and 1200 for every 1-hour.\n  - If compaction succeeds or requested revision has already been compacted, it resets period timer and removes used compacted revision from historical revision records (e.g. start next revision collect and compaction from previously collected revisions).\n  - If compaction fails, it retries in 5 minutes.\n- Allow snapshot over 512MB.\n\n### client v3\n\n- STM prefetching.\n- Add namespace feature.\n- Add `ErrOldCluster` with server version checking.\n- Translate `WithPrefix()` into `WithFromKey()` for empty key.\n\n### etcdctl v3\n\n- Add `check perf` command.\n- Add `etcdctl --from-key` flag to role grant-permission command.\n- `lock` command takes an optional command to execute.\n\n### gRPC Proxy\n\n- Proxy endpoint discovery.\n- Namespaces.\n- Coalesce lease requests.\n\n### etcd gateway\n\n- Support [DNS SRV priority](https://github.com/etcd-io/etcd/pull/7882) for [smart proxy routing](https://github.com/etcd-io/etcd/issues/4378).\n\n### Other\n\n- v3 client\n  - concurrency package's elections updated to match RPC interfaces.\n  - let client dial endpoints not in the balancer.\n- Release\n  - Annotate acbuild with supports-systemd-notify.\n  - Add `nsswitch.conf` to Docker container image.\n  - Add ppc64le, arm64(experimental) builds.\n\n### Go\n\n- Compile with [*Go 1.8.3*](https://golang.org/doc/devel/release.html#go1.8).\n\n\n---\n\n"

This release fixes [\"kube-apiserver 1.13.x refuses to work when first etcd-server is not available\" (kubernetes#72102)](https://github.com/kubernetes/kubernetes/issues/72102).\n\n### Breaking Changes\n\n- Rewrite [client balancer](https://github.com/etcd-io/etcd/pull/9860) with [new gRPC balancer interface](https://github.com/etcd-io/etcd/issues/9106).\n  - Upgrade [gRPC to v1.23.0](https://github.com/etcd-io/etcd/pull/10911).\n  - Improve [client balancer failover against secure endpoints](https://github.com/etcd-io/etcd/pull/10911).\n    - Fix [\"kube-apiserver 1.13.x refuses to work when first etcd-server is not available\" (kubernetes#72102)](https://github.com/kubernetes/kubernetes/issues/72102).\n  - [The new client balancer](https://etcd.io/docs/latest/learning/design-client/) uses an asynchronous resolver to pass endpoints to the gRPC dial function. to block until the underlying connection is up, pass `grpc.WithBlock()` to `clientv3.Config.DialOptions`.\n- Require [*Go 1.12+*](https://github.com/etcd-io/etcd/pull/10045).\n- Compile with [*Go 1.12.9*](https://golang.org/doc/devel/release.html#go1.12) including [*Go 1.12.8*](https://groups.google.com/d/msg/golang-announce/65QixT3tcmg/DrFiG6vvCwAJ) security fixes.\n- Migrate dependency management tool from `glide` to [Go module](https://github.com/etcd-io/etcd/pull/10063).\n  - <= 3.3 puts `vendor` directory under `cmd/vendor` directory to [prevent conflicting transitive dependencies](https://github.com/etcd-io/etcd/issues/4913).\n  - 3.4 moves `cmd/vendor` directory to `vendor` at repository root.\n  - Remove recursive symlinks in `cmd` directory.\n  - Now `go get/install/build` on `etcd` packages (e.g. `clientv3`, `tools/benchmark`) enforce builds with etcd `vendor` directory.\n- Deprecated `latest` [release container](https://console.cloud.google.com/gcr/images/etcd-development/GLOBAL/etcd) tag.\n  - **`docker pull gcr.io/etcd-development/etcd:latest` would not be up-to-date**.\n- Deprecated [minor](https://semver.org/) version [release container](https://console.cloud.google.com/gcr/images/etcd-development/GLOBAL/etcd) tags.\n  - `docker pull gcr.io/etcd-development/etcd:v3.3` would still work but may be stale.\n  - **`docker pull gcr.io/etcd-development/etcd:v3.4` would not work**.\n  - Use **`docker pull gcr.io/etcd-development/etcd:v3.3.14`** instead, with the exact patch version.\n- Deprecated [ACIs from official release](https://github.com/etcd-io/etcd/pull/9059).\n  - [AppC was officially suspended](https://github.com/appc/spec#-disclaimer-), as of late 2016.\n  - [`acbuild`](https://github.com/containers/build#this-project-is-currently-unmaintained) is not maintained anymore.\n  - `*.aci` files are not available from `v3.4` release.\n\n### etcd server\n\n- Add [`rpctypes.ErrLeaderChanged`](https://github.com/etcd-io/etcd/pull/10094).\n  - Now linearizable requests with read index would fail fast when there is a leadership change, instead of waiting until context timeout.\n- Fix [race condition in `rafthttp` transport pause/resume](https://github.com/etcd-io/etcd/pull/10826).\n\n### API\n\n- Add [`watch_id` field to `etcdserverpb.WatchCreateRequest`](https://github.com/etcd-io/etcd/pull/9065) to allow user-provided watch ID to `mvcc`.\n  - Corresponding `watch_id` is returned via `etcdserverpb.WatchResponse`, if any.\n- Add [`fragment` field to `etcdserverpb.WatchCreateRequest`](https://github.com/etcd-io/etcd/pull/9291) to request etcd server to [split watch events](https://github.com/etcd-io/etcd/issues/9294) when the total size of events exceeds `etcd --max-request-bytes` flag value plus gRPC-overhead 512 bytes.\n  - The default server-side request bytes limit is `embed.DefaultMaxRequestBytes` which is 1.5 MiB plus gRPC-overhead 512 bytes.\n  - If watch response events exceed this server-side request limit and watch request is created with `fragment` field `true`, the server will split watch events into a set of chunks, each of which is a subset of watch events below server-side request limit.\n  - Useful when client-side has limited bandwidths.\n  - For example, watch response contains 10 events, where each event is 1 MiB. And server `etcd --max-request-bytes` flag value is 1 MiB. Then, server will send 10 separate fragmented events to the client.\n  - For example, watch response contains 5 events, where each event is 2 MiB. And server `etcd --max-request-bytes` flag value is 1 MiB and `clientv3.Config.MaxCallRecvMsgSize` is 1 MiB. Then, server will try to send 5 separate fragmented events to the client, and the client will error with `\"code = ResourceExhausted desc = grpc: received message larger than max (...)\"`.\n  - Client must implement fragmented watch event merge (which `clientv3` does in etcd v3.4).\n- Add [`WatchRequest.WatchProgressRequest`](https://github.com/etcd-io/etcd/pull/9869).\n  - To manually trigger broadcasting watch progress event (empty watch response with latest header) to all associated watch streams.\n  - Think of it as `WithProgressNotify` that can be triggered manually.\n\n### Metrics, Monitoring\n\nSee [List of metrics](https://github.com/etcd-io/etcd/tree/main/Documentation/metrics) for all metrics per release.\n\nNote that any `etcd_debugging_*` metrics are experimental and subject to change.\n\n- Add [`etcd_network_snapshot_send_inflights_total`](https://github.com/etcd-io/etcd/pull/11009) Prometheus metric.\n- Add [`etcd_network_snapshot_receive_inflights_total`](https://github.com/etcd-io/etcd/pull/11009) Prometheus metric.\n- Add [`etcd_server_snapshot_apply_in_progress_total`](https://github.com/etcd-io/etcd/pull/11009) Prometheus metric.\n\n### client v3\n\n- Fix [gRPC panic \"send on closed channel](https://github.com/etcd-io/etcd/issues/9956) by upgrading [`google.golang.org/grpc`](https://github.com/grpc/grpc-go/releases) from [**`v1.7.5`**](https://github.com/grpc/grpc-go/releases/tag/v1.7.5) to [**`v1.23.0`**](https://github.com/grpc/grpc-go/releases/tag/v1.23.0).\n- Rewrite [client balancer](https://github.com/etcd-io/etcd/pull/9860) with [new gRPC balancer interface](https://github.com/etcd-io/etcd/issues/9106).\n  - Upgrade [gRPC to v1.23.0](https://github.com/etcd-io/etcd/pull/10911).\n  - Improve [client balancer failover against secure endpoints](https://github.com/etcd-io/etcd/pull/10911).\n    - Fix [\"kube-apiserver 1.13.x refuses to work when first etcd-server is not available\" (kubernetes#72102)](https://github.com/kubernetes/kubernetes/issues/72102).\n  - [The new client balancer](https://etcd.io/docs/latest/learning/design-client/) uses an asynchronous resolver to pass endpoints to the gRPC dial function. to block until the underlying connection is up, pass `grpc.WithBlock()` to `clientv3.Config.DialOptions`.\n\n### etcdctl v3\n\n- Add [`etcdctl endpoint health --write-out` support](https://github.com/etcd-io/etcd/pull/9540).\n  - Previously, [`etcdctl endpoint health --write-out json` did not work](https://github.com/etcd-io/etcd/issues/9532).\n  - The command output is changed. Previously, if endpoint is unreachable, the command output is\n  \"\\<endpoint\\> is unhealthy: failed to connect: \\<error message\\>\". This change unified the error message, all error types\n  now have the same output \"\\<endpoint\\> is unhealthy: failed to commit proposal: \\<error message\\>\".\n- Add [missing newline in `etcdctl endpoint health`](https://github.com/etcd-io/etcd/pull/10793).\n\n### Package `pkg/adt`\n\n- Change [`pkg/adt.IntervalTree` from `struct` to `interface`](https://github.com/etcd-io/etcd/pull/10959).\n  - See [`pkg/adt` README](https://github.com/etcd-io/etcd/tree/main/pkg/adt) and [`pkg/adt` godoc](https://godoc.org/go.etcd.io/etcd/pkg/adt).\n- Improve [`pkg/adt.IntervalTree` test coverage](https://github.com/etcd-io/etcd/pull/10959).\n  - See [`pkg/adt` README](https://github.com/etcd-io/etcd/tree/main/pkg/adt) and [`pkg/adt` godoc](https://godoc.org/go.etcd.io/etcd/pkg/adt).\n- Fix [Red-Black tree to maintain black-height property](https://github.com/etcd-io/etcd/pull/10978).\n  - Previously, delete operation violates [black-height property](https://github.com/etcd-io/etcd/issues/10965).\n\n### Go\n\n- Require [*Go 1.12+*](https://github.com/etcd-io/etcd/pull/10045).\n- Compile with [*Go 1.12.9*](https://golang.org/doc/devel/release.html#go1.12) including [*Go 1.12.8*](https://groups.google.com/d/msg/golang-announce/65QixT3tcmg/DrFiG6vvCwAJ) security fixes.\n\n\n---\n\n\n## [v3.3.13](https://github.com/etcd-io/etcd/releases/tag/v3.3.13) (2019-05-02)\n\nSee [code changes](https://github.com/etcd-io/etcd/compare/v3.3.12...v3.3.13) and [v3.3 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_3/) for any breaking changes.\n\n**Again, before running upgrades from any previous release, please make sure to read change logs below and [v3.3 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_3/).**\n\n### Improved\n\n- Improve [heartbeat send failure logging](https://github.com/etcd-io/etcd/pull/10663).\n- Add [`Verify` function to perform corruption check on WAL contents](https://github.com/etcd-io/etcd/pull/10603).\n\n### Metrics, Monitoring\n\nSee [List of metrics](https://github.com/etcd-io/etcd/tree/main/Documentation/metrics) for all metrics per release.\n\nNote that any `etcd_debugging_*` metrics are experimental and subject to change.\n\n- Fix bug where [db_compaction_total_duration_milliseconds metric incorrectly measured duration as 0](https://github.com/etcd-io/etcd/pull/10646).\n\n### client v3\n\n- Fix [`(*Client).Endpoints()` method race condition](https://github.com/etcd-io/etcd/pull/10595).\n\n### Package `wal`\n\n- Add [`Verify` function to perform corruption check on WAL contents](https://github.com/etcd-io/etcd/pull/10603).\n\n### Dependency\n\n- Migrate [`github.com/ugorji/go/codec`](https://github.com/ugorji/go/releases) to [**`github.com/json-iterator/go`**](https://github.com/json-iterator/go) (See [#10667](https://github.com/etcd-io/etcd/pull/10667) for more).\n- Migrate [`github.com/ghodss/yaml`](https://github.com/ghodss/yaml/releases) to [**`sigs.k8s.io/yaml`**](https://github.com/kubernetes-sigs/yaml) (See [#10718](https://github.com/etcd-io/etcd/pull/10718) for more).\n\n### Go\n\n- Compile with [*Go 1.10.8*](https://golang.org/doc/devel/release.html#go1.10).\n\n\n---\n\n\n## [v3.3.12](https://github.com/etcd-io/etcd/releases/tag/v3.3.12) (2019-02-07)\n\nSee [code changes](https://github.com/etcd-io/etcd/compare/v3.3.11...v3.3.12) and [v3.3 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_3/) for any breaking changes.\n\n**Again, before running upgrades from any previous release, please make sure to read change logs below and [v3.3 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_3/).**\n\n### etcdctl v3\n\n- [Strip out insecure endpoints from DNS SRV records when using discovery](https://github.com/etcd-io/etcd/pull/10443) with etcdctl v2\n\n### Go\n\n- Compile with [*Go 1.10.8*](https://golang.org/doc/devel/release.html#go1.10).\n\n\n---\n\n\n## [v3.3.11](https://github.com/etcd-io/etcd/releases/tag/v3.3.11) (2019-01-11)\n\nSee [code changes](https://github.com/etcd-io/etcd/compare/v3.3.10...v3.3.11) and [v3.3 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_3/) for any breaking changes.\n\n**Again, before running upgrades from any previous release, please make sure to read change logs below and [v3.3 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_3/).**\n\n### gRPC Proxy\n\n- Fix [memory leak in cache layer](https://github.com/etcd-io/etcd/pull/10327).\n\n### Security, Authentication\n\n- Disable [CommonName authentication for gRPC-gateway](https://github.com/etcd-io/etcd/pull/10366) gRPC-gateway proxy requests to etcd server use the etcd client server TLS certificate.

Let's assume that a watcher had been requested with a future revision X and sent to node A that became network-partitioned thereafter. Meanwhile, cluster makes progress. Then when the partition gets removed, the leader sends a snapshot to node A. Previously if the snapshot's latest revision is still lower than the watch revision X,  **etcd server panicked** during snapshot restore operation.\n  - Now, this server-side panic has been fixed.\n\n### Go\n\n- Compile with [*Go 1.9.6*](https://golang.org/doc/devel/release.html#go1.9).\n\n\n---\n\n\n## [v3.3.5](https://github.com/etcd-io/etcd/releases/tag/v3.3.5) (2018-05-09)\n\nSee [code changes](https://github.com/etcd-io/etcd/compare/v3.3.4...v3.3.5) and [v3.3 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_3/) for any breaking changes.\n\n**Again, before running upgrades from any previous release, please make sure to read change logs below and [v3.3 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_3/).**\n\n### etcdctl v3\n\n- Fix [`etcdctl watch [key] [range_end] -- [exec-command…]`](https://github.com/etcd-io/etcd/pull/9688) parsing.\n  - Previously,  `ETCDCTL_API=3 ./bin/etcdctl watch foo -- echo watch event received` panicked.\n\n### Go\n\n- Compile with [*Go 1.9.6*](https://golang.org/doc/devel/release.html#go1.9).\n\n\n---\n\n\n## [v3.3.4](https://github.com/etcd-io/etcd/releases/tag/v3.3.4) (2018-04-24)\n\nSee [code changes](https://github.com/etcd-io/etcd/compare/v3.3.3...v3.3.4) and [v3.3 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_3/) for any breaking changes.\n\n**Again, before running upgrades from any previous release, please make sure to read change logs below and [v3.3 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_3/).**\n\n### Metrics, Monitoring\n\nSee [List of metrics](https://github.com/etcd-io/etcd/tree/main/Documentation/metrics) for all metrics per release.\n\nNote that any `etcd_debugging_*` metrics are experimental and subject to change.\n\n- Add [`etcd_server_is_leader`](https://github.com/etcd-io/etcd/pull/9587) Prometheus metric.\n- Fix [`etcd_debugging_server_lease_expired_total`](https://github.com/etcd-io/etcd/pull/9557) Prometheus metric.\n- Fix [race conditions in v2 server stat collecting](https://github.com/etcd-io/etcd/pull/9562).\n\n### Security, Authentication\n\n- Fix [TLS reload](https://github.com/etcd-io/etcd/pull/9570) when [certificate SAN field only includes IP addresses but no domain names](https://github.com/etcd-io/etcd/issues/9541).\n  - In Go, server calls `(*tls.Config).GetCertificate` for TLS reload if and only if server's `(*tls.Config).Certificates` field is not empty, or `(*tls.ClientHelloInfo).ServerName` is not empty with a valid SNI from the client. Previously, etcd always populates `(*tls.Config).Certificates` on the initial client TLS handshake, as non-empty. Thus, client was always expected to supply a matching SNI in order to pass the TLS verification and to trigger `(*tls.Config).GetCertificate` to reload TLS assets.\n  - However, a certificate whose SAN field does [not include any domain names but only IP addresses](https://github.com/etcd-io/etcd/issues/9541) would request `*tls.ClientHelloInfo` with an empty `ServerName` field, thus failing to trigger the TLS reload on initial TLS handshake; this becomes a problem when expired certificates need to be replaced online.\n  - Now, `(*tls.Config).Certificates` is created empty on initial TLS client handshake, first to trigger `(*tls.Config).GetCertificate`, and then to populate rest of the certificates on every new TLS connection, even when client SNI is empty (e.g. cert only includes IPs).\n\n### etcd server\n\n- Add [`etcd --initial-election-tick-advance`](https://github.com/etcd-io/etcd/pull/9591) flag to configure initial election tick fast-forward.\n  - By default, `etcd --initial-election-tick-advance=true`, then local member fast-forwards election ticks to speed up \"initial\" leader election trigger.\n  - This benefits the case of larger election ticks. For instance, cross datacenter deployment may require longer election timeout of 10-second. If true, local node does not need wait up to 10-second. Instead, forwards its election ticks to 8-second, and have only 2-second left before leader election.\n  - Major assumptions are that: cluster has no active leader thus advancing ticks enables faster leader election. Or cluster already has an established leader, and rejoining follower is likely to receive heartbeats from the leader after tick advance and before election timeout.\n  - However, when network from leader to rejoining follower is congested, and the follower does not receive leader heartbeat within left election ticks, disruptive election has to happen thus affecting cluster availabilities.\n  - Now, this can be disabled by setting `--initial-election-tick-advance=false`.\n  - Disabling this would slow down initial bootstrap process for cross datacenter deployments. Make tradeoffs by configuring `etcd --initial-election-tick-advance` at the cost of slow initial bootstrap.\n  - If single-node, it advances ticks regardless.\n  - Address [disruptive rejoining follower node](https://github.com/etcd-io/etcd/issues/9333).\n\n### Package `embed`\n\n- Add [`embed.Config.InitialElectionTickAdvance`](https://github.com/etcd-io/etcd/pull/9591) to enable/disable initial election tick fast-forward.\n  - `embed.NewConfig()` would return `*embed.Config` with `InitialElectionTickAdvance` as true by default.\n\n### Go\n\n- Compile with [*Go 1.9.5*](https://golang.org/doc/devel/release.html#go1.9).\n\n\n---\n\n\n## [v3.3.3](https://github.com/etcd-io/etcd/releases/tag/v3.3.3) (2018-03-29)\n\nSee [code changes](https://github.com/etcd-io/etcd/compare/v3.3.2...v3.3.3) and [v3.3 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_3/) for any breaking changes.\n\n**Again, before running upgrades from any previous release, please make sure to read change logs below and [v3.3 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_3/).**\n\n### Improved\n\n- Adjust [election timeout on server restart](https://github.com/etcd-io/etcd/pull/9415) to reduce [disruptive rejoining servers](https://github.com/etcd-io/etcd/issues/9333).\n  - Previously, etcd fast-forwards election ticks on server start, with only one tick left for leader election. This is to speed up start phase, without having to wait until all election ticks elapse. Advancing election ticks is useful for cross datacenter deployments with larger election timeouts. However, it was affecting cluster availability if the last tick elapses before leader contacts the restarted node.\n  - Now, when etcd restarts, it adjusts election ticks with more than one tick left, thus more time for leader to prevent disruptive restart.\n- Adjust [periodic compaction retention window](https://github.com/etcd-io/etcd/pull/9485).\n  - e.g. `etcd --auto-compaction-mode=revision --auto-compaction-retention=1000` automatically `Compact` on `\"latest revision\" - 1000` every 5-minute (when latest revision is 30000, compact on revision 29000).\n  - e.g. Previously, `etcd --auto-compaction-mode=periodic --auto-compaction-retention=72h` automatically `Compact` with 72-hour retention windown for every 7.2-hour. **Now, `Compact` happens, for every 1-hour but still with 72-hour retention window.**\n  - e.g. Previously, `etcd --auto-compaction-mode=periodic --auto-compaction-retention=30m` automatically `Compact` with 30-minute retention windown for every 3-minute. **Now, `Compact` happens, for every 30-minute but still with 30-minute retention window.**\n  - Periodic compactor keeps recording latest revisions for every compaction period when given period is less than 1-hour, or for every 1-hour when given compaction period is greater than 1-hour (e.g. 1-hour when `etcd --auto-compaction-mode=periodic --auto-compaction-retention=24h`).\n  - For every compaction period or 1-hour, compactor uses the last revision that was fetched before compaction period, to discard historical data.\n  - The retention window of compaction period moves for every given compaction period or hour.\n  - For instance, when hourly writes are 100 and `etcd --auto-compaction-mode=periodic --auto-compaction-retention=24h`, `v3.2.x`, `v3.3.0`, `v3.3.1`, and `v3.3.2` compact revision 2400, 2640, and 2880 for every 2.4-hour, while `v3.3.3` *or later* compacts revision 2400, 2500, 2600 for every 1-hour.\n  - Furthermore, when `etcd --auto-compaction-mode=periodic --auto-compaction-retention=30m` and writes per minute are about 1000, `v3.3.0`, `v3.3.1`, and `v3.3.2` compact revision 30000, 33000, and 36000, for every 3-minute, while `v3.3.3` *or later* compacts revision 30000, 60000, and 90000, for every 30-minute.\n\n### Metrics, Monitoring\n\nSee [List of metrics](https://github.com/etcd-io/etcd/tree/main/Documentation/metrics) for all metrics per release.\n\nNote that any `etcd_debugging_*` metrics are experimental and subject to change.\n\n- Add missing [`etcd_network_peer_sent_failures_total` count](https://github.com/etcd-io/etcd/pull/9437).\n\n### Go\n\n- Compile with [*Go 1.9.5*](https://golang.org/doc/devel/release.html#go1.9).\n\n\n---\n\n\n## [v3.3.2](https://github.com/etcd-io/etcd/releases/tag/v3.3.2) (2018-03-08)\n\nSee [code changes](https://github.com/etcd-io/etcd/compare/v3.3.1...v3.3.2) and [v3.3 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_3/) for any breaking changes.\n\n**Again, before running upgrades from any previous release, please make sure to read change logs below and [v3.3 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_3/).**\n\n### etcd server\n\n- Fix [server panic on invalid Election Proclaim/Resign HTTP(S) requests](https://github.com/etcd-io/etcd/pull/9379).\n  - Previously, wrong-formatted HTTP requests to Election API could trigger panic in etcd server.\n  - e.g. `curl -L http://localhost:2379/v3/election/proclaim -X POST -d '{\"value\":\"\"}'`, `curl -L http://localhost:2379/v3/election/resign -X POST -d '{\"value\":\"\"}'`.\n- Fix [revision-based compaction retention parsing](https://github.com/etcd-io/etcd/pull/9339).\n  - Previously, `etcd --auto-compaction-mode revision --auto-compaction-retention 1` was [translated to revision retention 3600000000000](https://github.com/etcd-io/etcd/issues/9337).\n  - Now, `etcd --auto-compaction-mode revision --auto-compaction-retention 1` is correctly parsed as revision retention 1.\n- Prevent [overflow by large `TTL` values for `Lease` `Grant`](https://github.com/etcd-io/etcd/pull/9399).\n  - `TTL` parameter to `Grant` request is unit of second.\n  - Leases with too large `TTL` values exceeding `math.MaxInt64` [expire in unexpected ways](https://github.com/etcd-io/etcd/issues/9374).\n  - Server now returns `rpctypes.ErrLeaseTTLTooLarge` to client, when the requested `TTL` is larger than *9,000,000,000 seconds* (which is >285 years).\n  - Again, etcd `Lease` is meant for short-periodic keepalives or sessions, in the range of seconds or minutes.

When applying this snapshot, etcd watch storage moves current synced watchers to unsynced since sync watchers might have become stale during network partition. And reset synced watcher group to restart watcher routines. Previously, there was a bug when moving from synced watcher group to unsynced, thus client would miss events when the watcher was requested to the network-partitioned node.\n\n### Go\n\n- Compile with [*Go 1.9.4*](https://golang.org/doc/devel/release.html#go1.9).\n\n\n---\n\n\n## [v3.3.0](https://github.com/etcd-io/etcd/releases/tag/v3.3.0) (2018-02-01)\n\nSee [code changes](https://github.com/etcd-io/etcd/compare/v3.2.0...v3.3.0) and [v3.3 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_3/) for any breaking changes.\n\n- [v3.3.0](https://github.com/etcd-io/etcd/releases/tag/v3.3.0) (2018-02-01), see [code changes](https://github.com/etcd-io/etcd/compare/v3.3.0-rc.4...v3.3.0).\n- [v3.3.0-rc.4](https://github.com/etcd-io/etcd/releases/tag/v3.3.0-rc.4) (2018-01-22), see [code changes](https://github.com/etcd-io/etcd/compare/v3.3.0-rc.3...v3.3.0-rc.4).\n- [v3.3.0-rc.3](https://github.com/etcd-io/etcd/releases/tag/v3.3.0-rc.3) (2018-01-17), see [code changes](https://github.com/etcd-io/etcd/compare/v3.3.0-rc.2...v3.3.0-rc.3).\n- [v3.3.0-rc.2](https://github.com/etcd-io/etcd/releases/tag/v3.3.0-rc.2) (2018-01-11), see [code changes](https://github.com/etcd-io/etcd/compare/v3.3.0-rc.1...v3.3.0-rc.2).\n- [v3.3.0-rc.1](https://github.com/etcd-io/etcd/releases/tag/v3.3.0-rc.1) (2018-01-02), see [code changes](https://github.com/etcd-io/etcd/compare/v3.3.0-rc.0...v3.3.0-rc.1).\n- [v3.3.0-rc.0](https://github.com/etcd-io/etcd/releases/tag/v3.3.0-rc.0) (2017-12-20), see [code changes](https://github.com/etcd-io/etcd/compare/v3.2.0...v3.3.0-rc.0).\n\n**Again, before running upgrades from any previous release, please make sure to read change logs below and [v3.3 upgrade guide](https://etcd.io/docs/latest/upgrades/upgrade_3_3/).**\n\n### Improved\n\n- Use [`coreos/bbolt`](https://github.com/coreos/bbolt/releases) to replace [`boltdb/bolt`](https://github.com/boltdb/bolt#project-status).\n  -

To address [\"username and password specified in the request should take priority over CN in the cert\"](https://github.com/etcd-io/etcd/issues/8584).\n- Protect [lease revoke with auth](https://github.com/etcd-io/etcd/pull/8031).\n- Provide user's role on [auth permission error](https://github.com/etcd-io/etcd/pull/8164).\n- Fix [auth store panic with disabled token](https://github.com/etcd-io/etcd/pull/8695).\n\n### etcd server\n\n- Add [`etcd --experimental-initial-corrupt-check`](https://github.com/etcd-io/etcd/pull/8554) flag to [check cluster database hashes before serving client/peer traffic](https://github.com/etcd-io/etcd/issues/8313).\n  - `etcd --experimental-initial-corrupt-check=false` by default.\n  - v3.4 will enable `--initial-corrupt-check=true` by default.\n- Add [`etcd --experimental-corrupt-check-time`](https://github.com/etcd-io/etcd/pull/8420) flag to [raise corrupt alarm monitoring](https://github.com/etcd-io/etcd/issues/7125).\n  - `etcd --experimental-corrupt-check-time=0s` disabled by default.\n- Add [`etcd --experimental-enable-v2v3`](https://github.com/etcd-io/etcd/pull/8407) flag to [emulate v2 API with v3](https://github.com/etcd-io/etcd/issues/6925).\n  - `etcd --experimental-enable-v2v3=false` by default.\n- Add [`etcd --max-txn-ops`](https://github.com/etcd-io/etcd/pull/7976) flag to [configure maximum number operations in transaction](https://github.com/etcd-io/etcd/issues/7826).\n- Add [`etcd --max-request-bytes`](https://github.com/etcd-io/etcd/pull/7968) flag to [configure maximum client request size](https://github.com/etcd-io/etcd/issues/7923).\n  - If not configured, it defaults to 1.5 MiB.\n- Add [`etcd --client-crl-file`, `--peer-crl-file`](https://github.com/etcd-io/etcd/pull/8124) flags for [Certificate revocation list](https://github.com/etcd-io/etcd/issues/4034).\n- Add [`etcd --peer-cert-allowed-cn`](https://github.com/etcd-io/etcd/pull/8616) flag to support [CN-based auth for inter-peer connection](https://github.com/etcd-io/etcd/issues/8262).\n- Add [`etcd --listen-metrics-urls`](https://github.com/etcd-io/etcd/pull/8242) flag for additional `/metrics` and `/health` endpoints.\n  - Support [additional (non) TLS `/metrics` endpoints for a TLS-enabled cluster](https://github.com/etcd-io/etcd/pull/8282).\n  - e.g. `etcd --listen-metrics-urls=https://localhost:2378,http://localhost:9379` to serve `/metrics` and `/health` on secure port 2378 and insecure port 9379.\n  - Useful for [bypassing critical APIs when monitoring etcd](https://github.com/etcd-io/etcd/issues/8060).\n- Add [`etcd --auto-compaction-mode`](https://github.com/etcd-io/etcd/pull/8123) flag to [support revision-based compaction](https://github.com/etcd-io/etcd/issues/8098).\n- Change `etcd --auto-compaction-retention` flag to [accept string values](https://github.com/etcd-io/etcd/pull/8563) with [finer granularity](https://github.com/etcd-io/etcd/issues/8503).\n  - Now that `etcd --auto-compaction-retention` accepts string values, etcd configuration YAML file `auto-compaction-retention` field must be changed to `string` type.\n  - Previously, `etcd --config-file etcd.config.yaml` can have `auto-compaction-retention: 24` field, now must be `auto-compaction-retention: \"24\"` or `auto-compaction-retention: \"24h\"`.\n  - If configured as `--auto-compaction-mode periodic --auto-compaction-retention \"24h\"`, the time duration value for `etcd --auto-compaction-retention` flag must be valid for [`time.ParseDuration`](https://golang.org/pkg/time/#ParseDuration) function in Go.\n  - e.g. `etcd --auto-compaction-mode=revision --auto-compaction-retention=1000` automatically `Compact` on `\"latest revision\" - 1000` every 5-minute (when latest revision is 30000, compact on revision 29000).\n  - e.g. `etcd --auto-compaction-mode=periodic --auto-compaction-retention=72h` automatically `Compact` with 72-hour retention windown, for every 7.2-hour.\n  - e.g. `etcd --auto-compaction-mode=periodic --auto-compaction-retention=30m` automatically `Compact` with 30-minute retention windown, for every 3-minute.\n  - Periodic compactor continues to record latest revisions for every 1/10 of given compaction period (e.g. 1-hour when `etcd --auto-compaction-mode=periodic --auto-compaction-retention=10h`).\n  - For every 1/10 of given compaction period, compactor uses the last revision that was fetched before compaction period, to discard historical data.\n  - The retention window of compaction period moves for every 1/10 of given compaction period.\n  - For instance, when hourly writes are 100 and `--auto-compaction-retention=10`, v3.1 compacts revision 1000, 2000, and 3000 for every 10-hour, while v3.2.x, v3.3.0, v3.3.1, and v3.3.2 compact revision 1000, 1100, and 1200 for every 1-hour. Furthermore, when writes per minute are 1000, v3.3.0, v3.3.1, and v3.3.2 with `--auto-compaction-mode=periodic --auto-compaction-retention=30m` compact revision 30000, 33000, and 36000, for every 3-minute with more finer granularity.\n  - Whether compaction succeeds or not, this process repeats for every 1/10 of given compaction period. If compaction succeeds, it just removes compacted revision from historical revision records.\n- Add [`etcd --grpc-keepalive-min-time`, `etcd --grpc-keepalive-interval`, `etcd --grpc-keepalive-timeout`](https://github.com/etcd-io/etcd/pull/8535) flags to configure server-side keepalive policies.\n- Serve [`/health` endpoint as unhealthy](https://github.com/etcd-io/etcd/pull/8272) when [alarm (e.g. `NOSPACE`) is raised or there's no leader](https://github.com/etcd-io/etcd/issues/8207).\n  - Define [`etcdhttp.Health`](https://godoc.org/github.com/coreos/etcd/etcdserver/api/etcdhttp#Health) struct with JSON encoder.\n  - Note that `\"health\"` field is [`string` type, not `bool`](https://github.com/etcd-io/etcd/pull/9143).\n    - e.g. `{\"health\":\"false\"}`, `{\"health\":\"true\"}`\n  - [Remove `\"errors\"` field](https://github.com/etcd-io/etcd/pull/9162) since `v3.3.0-rc.3` (did exist only in `v3.3.0-rc.0`, `v3.3.0-rc.1`, `v3.3.0-rc.2`).\n- Move [logging setup to embed package](https://github.com/etcd-io/etcd/pull/8810)\n  - Disable gRPC server info-level logs by default (can be enabled with `etcd --debug` flag).\n- Use [monotonic time in Go 1.9](https://github.com/etcd-io/etcd/pull/8507) for `lease` package.\n- Warn on [empty hosts in advertise URLs](https://github.com/etcd-io/etcd/pull/8384).\n  - Address [advertise client URLs accepts empty hosts](https://github.com/etcd-io/etcd/issues/8379).\n  - etcd v3.4 will exit on this error.\n    - e.g. `etcd --advertise-client-urls=http://:2379`.\n- Warn on [shadowed environment variables](https://github.com/etcd-io/etcd/pull/8385).\n  - Address [error on shadowed environment variables](https://github.com/etcd-io/etcd/issues/8380).\n  - etcd v3.4 will exit on this error.\n\n### API\n\n- Support [ranges in transaction comparisons](https://github.com/etcd-io/etcd/pull/8025) for [disconnected linearized reads](https://github.com/etcd-io/etcd/issues/7924).\n- Add [nested transactions](https://github.com/etcd-io/etcd/pull/8102) to extend [proxy use cases](https://github.com/etcd-io/etcd/issues/7857).\n- Add [lease comparison target in transaction](https://github.com/etcd-io/etcd/pull/8324).\n- Add [lease list](https://github.com/etcd-io/etcd/pull/8358).\n- Add [hash by revision](https://github.com/etcd-io/etcd/pull/8263) for [better corruption checking against boltdb](https://github.com/etcd-io/etcd/issues/8016).\n\n### client v3\n\n- Add [health balancer](https://github.com/etcd-io/etcd/pull/8545) to fix [watch API hangs](https://github.com/etcd-io/etcd/issues/7247), improve [endpoint switch under network faults](https://github.com/etcd-io/etcd/issues/7941).\n- [Refactor balancer](https://github.com/etcd-io/etcd/pull/8840) and add [client-side keepalive pings](https://github.com/etcd-io/etcd/pull/8199) to handle [network partitions](https://github.com/etcd-io/etcd/issues/8711).\n- Add [`MaxCallSendMsgSize` and `MaxCallRecvMsgSize`](https://github.com/etcd-io/etcd/pull/9047) fields to [`clientv3.Config`](https://godoc.org/github.com/coreos/etcd/clientv3#Config).\n  - Fix [exceeded response size limit error in client-side](https://github.com/etcd-io/etcd/issues/9043).\n  - Address [kubernetes#51099](https://github.com/kubernetes/kubernetes/issues/51099).\n    - In previous versions(v3.2.10, v3.2.11), client response size was limited to only 4 MiB.\n  - `MaxCallSendMsgSize` default value is 2 MiB, if not configured.\n  - `MaxCallRecvMsgSize` default value is `math.MaxInt32`, if not configured.\n- Accept [`Compare_LEASE`](https://github.com/etcd-io/etcd/pull/8324) in [`clientv3.Compare`](https://godoc.org/github.com/coreos/etcd/clientv3#Compare).\n- Add [`LeaseValue` helper](https://github.com/etcd-io/etcd/pull/8488) to `Cmp` `LeaseID` values in `Txn`.\n- Add [`MoveLeader`](https://github.com/etcd-io/etcd/pull/8153) to `Maintenance`.\n- Add [`HashKV`](https://github.com/etcd-io/etcd/pull/8351) to `Maintenance`.\n- Add [`Leases`](https://github.com/etcd-io/etcd/pull/8358) to `Lease`.\n- Add [`clientv3/ordering`](https://github.com/etcd-io/etcd/pull/8092) for enforce [ordering in serialized requests](https://github.com/etcd-io/etcd/issues/7623).\n- Fix [\"put at-most-once\" violation](https://github.com/etcd-io/etcd/pull/8335).\n- Fix [`WatchResponse.Canceled`](https://github.com/etcd-io/etcd/pull/8283) on [compacted watch request](https://github.com/etcd-io/etcd/issues/8231).\n- Fix [`concurrency/stm` `Put` with serializable snapshot](https://github.com/etcd-io/etcd/pull/8439).\n  -

To deprecate [`/v3alpha`](https://github.com/etcd-io/etcd/issues/8125) in v3.4.\n  - In v3.3, `curl -L http://localhost:2379/v3alpha/kv/put -X POST -d '{\"key\": \"Zm9v\", \"value\": \"YmFy\"}'` still works as a fallback to `curl -L http://localhost:2379/v3beta/kv/put -X POST -d '{\"key\": \"Zm9v\", \"value\": \"YmFy\"}'`, but `curl -L http://localhost:2379/v3alpha/kv/put -X POST -d '{\"key\": \"Zm9v\", \"value\": \"YmFy\"}'` won't work in v3.4. Use `curl -L http://localhost:2379/v3beta/kv/put -X POST -d '{\"key\": \"Zm9v\", \"value\": \"YmFy\"}'` instead.\n- Support [\"authorization\" token](https://github.com/etcd-io/etcd/pull/7999).\n- Support [websocket for bi-directional streams](https://github.com/etcd-io/etcd/pull/8257).\n  - Fix [`Watch` API with gRPC gateway](https://github.com/etcd-io/etcd/issues/8237).\n- Upgrade gRPC gateway to [v1.3.0](https://github.com/etcd-io/etcd/issues/8838).\n\n### etcd server\n\n- Fix [backend database in-memory index corruption](https://github.com/etcd-io/etcd/pull/8127) issue on restore (only 3.2.0 is affected).\n- Fix [watch restore from snapshot](https://github.com/etcd-io/etcd/pull/8427).\n- Fix [`mvcc/backend.defragdb` nil-pointer dereference on create bucket failure](https://github.com/etcd-io/etcd/pull/9119).\n- Fix [server crash](https://github.com/etcd-io/etcd/pull/8010) on [invalid transaction request from gRPC gateway](https://github.com/etcd-io/etcd/issues/7889).\n- Prevent [server panic from member update/add](https://github.com/etcd-io/etcd/pull/9174) with [wrong scheme URLs](https://github.com/etcd-io/etcd/issues/9173).\n- Make [peer dial timeout longer](https://github.com/etcd-io/etcd/pull/8599).\n  - See [coreos/etcd-operator#1300](https://github.com/etcd-io/etcd-operator/issues/1300) for more detail.\n- Make server [wait up to request time-out](https://github.com/etcd-io/etcd/pull/8267) with [pending RPCs](https://github.com/etcd-io/etcd/issues/8224).\n- Fix [`grpc.Server` panic on `GracefulStop`](https://github.com/etcd-io/etcd/pull/8987) with [TLS-enabled server](https://github.com/etcd-io/etcd/issues/8916).\n- Fix [\"multiple peer URLs cannot start\" issue](https://github.com/etcd-io/etcd/issues/8383).\n- Fix server-side auth so [concurrent auth operations do not return old revision error](https://github.com/etcd-io/etcd/pull/8442).\n- Handle [WAL renaming failure on Windows](https://github.com/etcd-io/etcd/pull/8286).\n- Upgrade [`coreos/go-systemd`](https://github.com/coreos/go-systemd/releases) to `v15` (see https://github.com/coreos/go-systemd/releases/tag/v15).\n- [Put back `/v2/machines`](https://github.com/etcd-io/etcd/pull/8062) endpoint for python-etcd wrapper.\n\n### client v2\n\n- [Fail-over v2 client](https://github.com/etcd-io/etcd/pull/8519) to next endpoint on [oneshot failure](https://github.com/etcd-io/etcd/issues/8515).\n\n### Package `raft`\n\n- Add [non-voting member](https://github.com/etcd-io/etcd/pull/8751).\n  - To implement [Raft thesis 4.2.1 Catching up new servers](https://github.com/etcd-io/etcd/issues/8568).\n  - `Learner` node does not vote or promote itself.\n\n### Other\n\n- Support previous two minor versions (see our [new release policy](https://github.com/etcd-io/etcd/pull/8805)).\n- `v3.3.x` is the last release cycle that supports `ACI`.\n  - [AppC was officially suspended](https://github.com/appc/spec#-disclaimer-), as of late 2016.\n  - [`acbuild`](https://github.com/containers/build#this-project-is-currently-unmaintained) is not maintained anymore.\n  - `*.aci` files won't be available from etcd v3.4 release.\n- Add container registry [`gcr.io/etcd-development/etcd`](https://gcr.io/etcd-development/etcd).\n  - [quay.io/coreos/etcd](https://quay.io/coreos/etcd) is still supported as secondary.\n\n### Go\n\n- Require [*Go 1.9+*](https://github.com/etcd-io/etcd/issues/6174).\n- Compile with [*Go 1.9.3*](https://golang.org/doc/devel/release.html#go1.9).\n- Deprecate [`golang.org/x/net/context`](https://github.com/etcd-io/etcd/pull/8511).\n\n\n---\n\n"

This is to speed up start phase, without having to wait until all election ticks elapse. Advancing election ticks is useful for cross datacenter deployments with larger election timeouts. However, it was affecting cluster availability if the last tick elapses before leader contacts the restarted node.\n  - Now, when etcd restarts, it adjusts election ticks with more than one tick left, thus more time for leader to prevent disruptive restart.\n- Add [Raft Pre-Vote feature](https://github.com/etcd-io/etcd/pull/9352) to reduce [disruptive rejoining servers](https://github.com/etcd-io/etcd/issues/9333).\n  - For instance, a flaky(or rejoining) member may drop in and out, and start campaign. This member will end up with a higher term, and ignore all incoming messages with lower term. In this case, a new leader eventually need to get elected, thus disruptive to cluster availability. Raft implements Pre-Vote phase to prevent this kind of disruptions. If enabled, Raft runs an additional phase of election to check if pre-candidate can get enough votes to win an election.\n- Adjust [periodic compaction retention window](https://github.com/etcd-io/etcd/pull/9485).\n  - e.g. `etcd --auto-compaction-mode=revision --auto-compaction-retention=1000` automatically `Compact` on `\"latest revision\" - 1000` every 5-minute (when latest revision is 30000, compact on revision 29000).\n  - e.g. Previously, `etcd --auto-compaction-mode=periodic --auto-compaction-retention=24h` automatically `Compact` with 24-hour retention windown for every 2.4-hour. Now, `Compact` happens for every 1-hour.\n  - e.g. Previously, `etcd --auto-compaction-mode=periodic --auto-compaction-retention=30m` automatically `Compact` with 30-minute retention windown for every 3-minute. Now, `Compact` happens for every 30-minute.\n  - Periodic compactor keeps recording latest revisions for every compaction period when given period is less than 1-hour, or for every 1-hour when given compaction period is greater than 1-hour (e.g. 1-hour when `etcd --auto-compaction-mode=periodic --auto-compaction-retention=24h`).\n  - For every compaction period or 1-hour, compactor uses the last revision that was fetched before compaction period, to discard historical data.\n  - The retention window of compaction period moves for every given compaction period or hour.\n  - For instance, when hourly writes are 100 and `etcd --auto-compaction-mode=periodic --auto-compaction-retention=24h`, `v3.2.x`, `v3.3.0`, `v3.3.1`, and `v3.3.2` compact revision 2400, 2640, and 2880 for every 2.4-hour, while `v3.3.3` *or later* compacts revision 2400, 2500, 2600 for every 1-hour.\n  - Furthermore, when `etcd --auto-compaction-mode=periodic --auto-compaction-retention=30m` and writes per minute are about 1000, `v3.3.0`, `v3.3.1`, and `v3.3.2` compact revision 30000, 33000, and 36000, for every 3-minute, while `v3.3.3` *or later* compacts revision 30000, 60000, and 90000, for every 30-minute.\n- Improve [lease expire/revoke operation performance](https://github.com/etcd-io/etcd/pull/9418), address [lease scalability issue](https://github.com/etcd-io/etcd/issues/9496).\n- Make [Lease `Lookup` non-blocking with concurrent `Grant`/`Revoke`](https://github.com/etcd-io/etcd/pull/9229).\n- Make etcd server return `raft.ErrProposalDropped` on internal Raft proposal drop in [v3 applier](https://github.com/etcd-io/etcd/pull/9549) and [v2 applier](https://github.com/etcd-io/etcd/pull/9558).\n  - e.g. a node is removed from cluster, or [`raftpb.MsgProp` arrives at current leader while there is an ongoing leadership transfer](https://github.com/etcd-io/etcd/issues/8975).\n- Add [`snapshot`](https://github.com/etcd-io/etcd/pull/9118) package for easier snapshot workflow (see [`godoc.org/github.com/etcd/clientv3/snapshot`](https://godoc.org/github.com/etcd-io/etcd/clientv3/snapshot) for more).\n- Improve [functional tester](https://github.com/etcd-io/etcd/tree/main/functional) coverage: [proxy layer to run network fault tests in CI](https://github.com/etcd-io/etcd/pull/9081), [TLS is enabled both for server and client](https://github.com/etcd-io/etcd/pull/9534), [liveness mode](https://github.com/etcd-io/etcd/issues/9230), [shuffle test sequence](https://github.com/etcd-io/etcd/issues/9381), [membership reconfiguration failure cases](https://github.com/etcd-io/etcd/pull/9564), [disastrous quorum loss and snapshot recover from a seed member](https://github.com/etcd-io/etcd/pull/9565), [embedded etcd](https://github.com/etcd-io/etcd/pull/9572).\n- Improve [index compaction blocking](https://github.com/etcd-io/etcd/pull/9511) by using a copy on write clone to avoid holding the lock for the traversal of the entire index.\n- Update [JWT methods](https://github.com/etcd-io/etcd/pull/9883) to allow for use of any supported signature method/algorithm.\n- Add [Lease checkpointing](https://github.com/etcd-io/etcd/pull/9924) to persist remaining TTLs to the consensus log periodically so that long lived leases progress toward expiry in the presence of leader elections and server restarts.\n  - Enabled by experimental flag \"--experimental-enable-lease-checkpoint\".\n- Add [gRPC interceptor for debugging logs](https://github.com/etcd-io/etcd/pull/9990); enable `etcd --debug` flag to see per-request debug information.\n- Add [consistency check in snapshot status](https://github.com/etcd-io/etcd/pull/10109). If consistency check on snapshot file fails, `snapshot status` returns `\"snapshot file integrity check failed...\"` error.\n- Add [`Verify` function to perform corruption check on WAL contents](https://github.com/etcd-io/etcd/pull/10603).\n- Improve [heartbeat send failure logging](https://github.com/etcd-io/etcd/pull/10663).\n- Support [users with no password](https://github.com/etcd-io/etcd/pull/9817) for reducing security risk introduced by leaked password. The users can only be authenticated with `CommonName` based auth.\n- Add `etcd --experimental-peer-skip-client-san-verification` to [skip verification of peer client address](https://github.com/etcd-io/etcd/pull/10524).\n- Add `etcd --experimental-compaction-batch-limit` to [sets the maximum revisions deleted in each compaction batch](https://github.com/etcd-io/etcd/pull/11034).\n- Reduced default compaction batch size from 10k revisions to 1k revisions to improve p99 latency during compactions and reduced wait between compactions from 100ms to 10ms.\n\n### Breaking Changes\n\n- Rewrite [client balancer](https://github.com/etcd-io/etcd/pull/9860) with [new gRPC balancer interface](https://github.com/etcd-io/etcd/issues/9106).\n  - Upgrade [gRPC to v1.23.0](https://github.com/etcd-io/etcd/pull/10911).\n  - Improve [client balancer failover against secure endpoints](https://github.com/etcd-io/etcd/pull/10911).\n    - Fix [\"kube-apiserver 1.13.x refuses to work when first etcd-server is not available\" (kubernetes#72102)](https://github.com/kubernetes/kubernetes/issues/72102).\n  - Fix [gRPC panic \"send on closed channel](https://github.com/etcd-io/etcd/issues/9956).\n  - [The new client balancer](https://etcd.io/docs/latest/learning/design-client/) uses an asynchronous resolver to pass endpoints to the gRPC dial function.

Then, all HTTP endpoints of etcd server listening on `\"localhost\"` becomes accessible, thus vulnerable to [DNS rebinding attacks (CVE-2018-5702)](https://bugs.chromium.org/p/project-zero/issues/detail?id=1447#c2).\n  - Client origin enforce policy works as follow:\n    - If client connection is secure via HTTPS, allow any hostnames..\n    - If client connection is not secure and `\"HostWhitelist\"` is not empty, only allow HTTP requests whose Host field is listed in whitelist.\n  - By default, `\"HostWhitelist\"` is `\"*\"`, which means insecure server allows all client HTTP requests.\n  - Note that the client origin policy is enforced whether authentication is enabled or not, for tighter controls.\n  - When specifying hostnames, loopback addresses are not added automatically. To allow loopback interfaces, add them to whitelist manually (e.g. `\"localhost\"`, `\"127.0.0.1\"`, etc.).\n  - e.g. `etcd --host-whitelist example.com`, then the server will reject all HTTP requests whose Host field is not `example.com` (also rejects requests to `\"localhost\"`).\n- Support [`etcd --cors`](https://github.com/etcd-io/etcd/pull/9490) in v3 HTTP requests (gRPC gateway).\n- Support [`ttl` field for `etcd` Authentication JWT token](https://github.com/etcd-io/etcd/pull/8302).\n  - e.g. `etcd --auth-token jwt,pub-key=<pub key path>,priv-key=<priv key path>,sign-method=<sign method>,ttl=5m`.\n- Allow empty token provider in [`etcdserver.ServerConfig.AuthToken`](https://github.com/etcd-io/etcd/pull/9369).\n- Fix [TLS reload](https://github.com/etcd-io/etcd/pull/9570) when [certificate SAN field only includes IP addresses but no domain names](https://github.com/etcd-io/etcd/issues/9541).\n  - In Go, server calls `(*tls.Config).GetCertificate` for TLS reload if and only if server's `(*tls.Config).Certificates` field is not empty, or `(*tls.ClientHelloInfo).ServerName` is not empty with a valid SNI from the client. Previously, etcd always populates `(*tls.Config).Certificates` on the initial client TLS handshake, as non-empty. Thus, client was always expected to supply a matching SNI in order to pass the TLS verification and to trigger `(*tls.Config).GetCertificate` to reload TLS assets.\n  - However, a certificate whose SAN field does [not include any domain names but only IP addresses](https://github.com/etcd-io/etcd/issues/9541) would request `*tls.ClientHelloInfo` with an empty `ServerName` field, thus failing to trigger the TLS reload on initial TLS handshake; this becomes a problem when expired certificates need to be replaced online.\n  - Now, `(*tls.Config).Certificates` is created empty on initial TLS client handshake, first to trigger `(*tls.Config).GetCertificate`, and then to populate rest of the certificates on every new TLS connection, even when client SNI is empty (e.g. cert only includes IPs).\n\n### etcd server\n\n- Add [`rpctypes.ErrLeaderChanged`](https://github.com/etcd-io/etcd/pull/10094).\n  - Now linearizable requests with read index would fail fast when there is a leadership change, instead of waiting until context timeout.\n- Add [`etcd --initial-election-tick-advance`](https://github.com/etcd-io/etcd/pull/9591) flag to configure initial election tick fast-forward.\n  - By default, `etcd --initial-election-tick-advance=true`, then local member fast-forwards election ticks to speed up \"initial\" leader election trigger.\n  - This benefits the case of larger election ticks. For instance, cross datacenter deployment may require longer election timeout of 10-second. If true, local node does not need wait up to 10-second. Instead, forwards its election ticks to 8-second, and have only 2-second left before leader election.\n  - Major assumptions are that: cluster has no active leader thus advancing ticks enables faster leader election. Or cluster already has an established leader, and rejoining follower is likely to receive heartbeats from the leader after tick advance and before election timeout.\n  - However, when network from leader to rejoining follower is congested, and the follower does not receive leader heartbeat within left election ticks, disruptive election has to happen thus affecting cluster availabilities.\n  - Now, this can be disabled by setting `etcd --initial-election-tick-advance=false`.\n  - Disabling this would slow down initial bootstrap process for cross datacenter deployments. Make tradeoffs by configuring `etcd --initial-election-tick-advance` at the cost of slow initial bootstrap.\n  - If single-node, it advances ticks regardless.\n  - Address [disruptive rejoining follower node](https://github.com/etcd-io/etcd/issues/9333).\n- Add [`etcd --pre-vote`](https://github.com/etcd-io/etcd/pull/9352) flag to enable to run an additional Raft election phase.\n  - For instance, a flaky(or rejoining) member may drop in and out, and start campaign. This member will end up with a higher term, and ignore all incoming messages with lower term. In this case, a new leader eventually need to get elected, thus disruptive to cluster availability. Raft implements Pre-Vote phase to prevent this kind of disruptions. If enabled, Raft runs an additional phase of election to check if pre-candidate can get enough votes to win an election.\n  - `etcd --pre-vote=false` by default.\n  - v3.5 will enable `etcd --pre-vote=true` by default.\n- Add `etcd --experimental-compaction-batch-limit` to [sets the maximum revisions deleted in each compaction batch](https://github.com/etcd-io/etcd/pull/11034).\n- Reduced default compaction batch size from 10k revisions to 1k revisions to improve p99 latency during compactions and reduced wait between compactions from 100ms to 10ms.\n- Add [`etcd --discovery-srv-name`](https://github.com/etcd-io/etcd/pull/8690) flag to support custom DNS SRV name with discovery.\n  - If not given, etcd queries `_etcd-server-ssl._tcp.[YOUR_HOST]` and `_etcd-server._tcp.[YOUR_HOST]`.\n  - If `etcd --discovery-srv-name=\"foo\"`, then query `_etcd-server-ssl-foo._tcp.[YOUR_HOST]` and `_etcd-server-foo._tcp.[YOUR_HOST]`.\n  - Useful for operating multiple etcd clusters under the same domain.\n- Support TLS cipher suite whitelisting.\n  - To block [weak cipher suites](https://github.com/etcd-io/etcd/issues/8320).\n  - TLS handshake fails when client hello is requested with invalid cipher suites.\n  - Add [`etcd --cipher-suites`](https://github.com/etcd-io/etcd/pull/9801) flag.\n  - If empty, Go auto-populates the list.\n- Support [`etcd --cors`](https://github.com/etcd-io/etcd/pull/9490) in v3 HTTP requests (gRPC gateway).\n- Rename [`etcd --log-output` to `etcd --log-outputs`](https://github.com/etcd-io/etcd/pull/9624) to support multiple log outputs.\n  - **`etcd --log-output` will be deprecated in v3.5**.\n- Add [`etcd --logger`](https://github.com/etcd-io/etcd/pull/9572) flag to support [structured logger and multiple log outputs](https://github.com/etcd-io/etcd/issues/9438) in server-side.\n  - **`etcd --logger=capnslog` will be deprecated in v3.5**.\n  - Main motivation is to promote automated etcd monitoring, rather than looking back server logs when it starts breaking. Future development will make etcd log as few as possible, and make etcd easier to monitor with metrics and alerts.\n  - `etcd --logger=capnslog --log-outputs=default` is the default setting and same as previous etcd server logging format.\n  - `etcd --logger=zap --log-outputs=default` is not supported when `etcd --logger=zap`.\n    - Use `etcd --logger=zap --log-outputs=stderr` instead.\n    - Or, use `etcd --logger=zap --log-outputs=systemd/journal` to send logs to the local systemd journal.\n    - Previously, if etcd parent process ID (PPID) is 1 (e.g. run with systemd), `etcd --logger=capnslog --log-outputs=default` redirects server logs to local systemd journal. And if write to journald fails, it writes to `os.Stderr` as a fallback.\n    - However, even with PPID 1, it can fail to dial systemd journal (e.g. run embedded etcd with Docker container). Then, [every single log write will fail](https://github.com/etcd-io/etcd/pull/9729) and fall back to `os.Stderr`, which is inefficient.\n    - To avoid this problem, systemd journal logging must be configured manually.\n  - `etcd --logger=zap --log-outputs=stderr` will log server operations in [JSON-encoded format](https://godoc.org/go.uber.org/zap#NewProductionEncoderConfig) and writes logs to `os.Stderr`. Use this to override journald log redirects.\n  - `etcd --logger=zap --log-outputs=stdout` will log server operations in [JSON-encoded format](https://godoc.org/go.uber.org/zap#NewProductionEncoderConfig) and writes logs to `os.Stdout` Use this to override journald log redirects.\n  - `etcd --logger=zap --log-outputs=a.log` will log server operations in [JSON-encoded format](https://godoc.org/go.uber.org/zap#NewProductionEncoderConfig) and writes logs to the specified file `a.log`.\n  - `etcd --logger=zap --log-outputs=a.log,b.log,c.log,stdout` [writes server logs to multiple files `a.log`, `b.log` and `c.log` at the same time](https://github.com/etcd-io/etcd/pull/9579) and outputs to `os.Stderr`, in [JSON-encoded format](https://godoc.org/go.uber.org/zap#NewProductionEncoderConfig).\n  - `etcd --logger=zap --log-outputs=/dev/null` will discard all server logs.\n- Add [`etcd --log-level`](https://github.com/etcd-io/etcd/pull/10947) flag to support log level.\n  - v3.5 will deprecate `etcd --debug` flag in favor of `etcd --log-level=debug`.\n- Add [`etcd --backend-batch-limit`](https://github.com/etcd-io/etcd/pull/10283) flag.\n- Add [`etcd --backend-batch-interval`](https://github.com/etcd-io/etcd/pull/10283) flag.\n- Fix [`mvcc` \"unsynced\" watcher restore operation](https://github.com/etcd-io/etcd/pull/9281).\n  - \"unsynced\" watcher is watcher that needs to be in sync with events that have happened.\n  - That is, \"unsynced\" watcher is the slow watcher that was requested on old revision.\n  - \"unsynced\" watcher restore operation was not correctly populating its underlying watcher group.\n  - Which possibly causes [missing events from \"unsynced\" watchers](https://github.com/etcd-io/etcd/issues/9086).\n  - A node gets network partitioned with a watcher on a future revision, and falls behind receiving a leader snapshot after partition gets removed. When applying this snapshot, etcd watch storage moves current synced watchers to unsynced since sync watchers might have become stale during network partition. And reset synced watcher group to restart watcher routines. Previously, there was a bug when moving from synced watcher group to unsynced, thus client would miss events when the watcher was requested to the network-partitioned node.\n- Fix [`mvcc` server panic from restore operation](https://github.com/etcd-io/etcd/pull/9775).\n  - Let's assume that a watcher had been requested with a future revision X and sent to node A that became network-partitioned thereafter. Meanwhile, cluster makes progress. Then when the partition gets removed, the leader sends a snapshot to node A. Previously if the snapshot's latest revision is still lower than the watch revision X,  **etcd server panicked** during snapshot restore operation.\n  - Now, this server-side panic has been fixed.\n- Fix [server panic on invalid Election Proclaim/Resign HTTP(S) requests](https://github.com/etcd-io/etcd/pull/9379).\n  - Previously, wrong-formatted HTTP requests to Election API could trigger panic in etcd server.\n  - e.g. `curl -L http://localhost:2379/v3/election/proclaim -X POST -d '{\"value\":\"\"}'`, `curl -L http://localhost:2379/v3/election/resign -X POST -d '{\"value\":\"\"}'`.\n- Fix [revision-based compaction retention parsing](https://github.com/etcd-io/etcd/pull/9339).\n  - Previously, `etcd --auto-compaction-mode revision --auto-compaction-retention 1` was [translated to revision retention 3600000000000](https://github.com/etcd-io/etcd/issues/9337).\n  - Now, `etcd --auto-compaction-mode revision --auto-compaction-retention 1` is correctly parsed as revision retention 1.\n- Prevent [overflow by large `TTL` values for `Lease` `Grant`](https://github.com/etcd-io/etcd/pull/9399).\n  - `TTL` parameter to `Grant` request is unit of second.\n  - Leases with too large `TTL` values exceeding `math.MaxInt64` [expire in unexpected ways](https://github.com/etcd-io/etcd/issues/9374).\n  - Server now returns `rpctypes.ErrLeaseTTLTooLarge` to client, when the requested `TTL` is larger than *9,000,000,000 seconds* (which is >285 years).\n  - Again, etcd `Lease` is meant for short-periodic keepalives or sessions, in the range of seconds or minutes. Not for hours or days!\n- Fix [expired lease revoke](https://github.com/etcd-io/etcd/pull/10693).\n  - Fix [\"the key is not deleted when the bound lease expires\"](https://github.com/etcd-io/etcd/issues/10686).\n- Enable etcd server [`raft.Config.CheckQuorum` when starting with `ForceNewCluster`](https://github.com/etcd-io/etcd/pull/9347).\n- Allow [non-WAL files in `etcd --wal-dir` directory](https://github.com/etcd-io/etcd/pull/9743).\n  - Previously, existing files such as [`lost+found`](https://github.com/etcd-io/etcd/issues/7287) in WAL directory prevent etcd server boot.\n  - Now, WAL directory that contains only `lost+found` or a file that's not suffixed with `.wal` is considered non-initialized.\n- Fix [`ETCD_CONFIG_FILE` env variable parsing in `etcd`](https://github.com/etcd-io/etcd/pull/10762).\n- Fix [race condition in `rafthttp` transport pause/resume](https://github.com/etcd-io/etcd/pull/10826).\n- Fix [server crash from creating an empty role](https://github.com/etcd-io/etcd/pull/10907).\n  - Previously, creating a role with an empty name crashed etcd server with an error code `Unavailable`.\n  - Now, creating a role with an empty name is not allowed with an error code `InvalidArgument`.\n\n### API\n\n- Add `isLearner` field to `etcdserverpb.Member`, `etcdserverpb.MemberAddRequest` and `etcdserverpb.StatusResponse` as part of [raft learner implementation](https://github.com/etcd-io/etcd/pull/10725).\n- Add `MemberPromote` rpc to `etcdserverpb.Cluster` interface and the corresponding `MemberPromoteRequest` and `MemberPromoteResponse` as part of [raft learner implementation](https://github.com/etcd-io/etcd/pull/10725).\n- Add [`snapshot`](https://github.com/etcd-io/etcd/pull/9118) package for snapshot restore/save operations (see [`godoc.org/github.com/etcd/clientv3/snapshot`](https://godoc.org/github.com/coreos/etcd/clientv3/snapshot) for more).\n- Add [`watch_id` field to `etcdserverpb.WatchCreateRequest`](https://github.com/etcd-io/etcd/pull/9065) to allow user-provided watch ID to `mvcc`.\n  - Corresponding `watch_id` is returned via `etcdserverpb.WatchResponse`, if any.\n- Add [`fragment` field to `etcdserverpb.WatchCreateRequest`](https://github.com/etcd-io/etcd/pull/9291) to request etcd server to [split watch events](https://github.com/etcd-io/etcd/issues/9294) when the total size of events exceeds `etcd --max-request-bytes` flag value plus gRPC-overhead 512 bytes.\n  - The default server-side request bytes limit is `embed.DefaultMaxRequestBytes` which is 1.5 MiB plus gRPC-overhead 512 bytes.\n  - If watch response events exceed this server-side request limit and watch request is created with `fragment` field `true`, the server will split watch events into a set of chunks, each of which is a subset of watch events below server-side request limit.\n  - Useful when client-side has limited bandwidths.\n  - For example, watch response contains 10 events, where each event is 1 MiB. And server `etcd --max-request-bytes` flag value is 1 MiB. Then, server will send 10 separate fragmented events to the client.\n  - For example, watch response contains 5 events, where each event is 2 MiB. And server `etcd --max-recv-bytes` flag value is 1 MiB and `clientv3.Config.MaxCallRecvMsgSize` is 1 MiB. Then, server will try to send 5 separate fragmented events to the client, and the client will error with `\"code = ResourceExhausted desc = grpc: received message larger than max (...)\"`.\n  - Client must implement fragmented watch event merge (which `clientv3` does in etcd v3.4).\n- Add [`raftAppliedIndex` field to `etcdserverpb.StatusResponse`](https://github.com/etcd-io/etcd/pull/9176) for current Raft applied index.\n- Add [`errors` field to `etcdserverpb.StatusResponse`](https://github.com/etcd-io/etcd/pull/9206) for server-side error.\n  - e.g. `\"etcdserver: no leader\", \"NOSPACE\", \"CORRUPT\"`\n- Add [`dbSizeInUse` field to `etcdserverpb.StatusResponse`](https://github.com/etcd-io/etcd/pull/9256) for actual DB size after compaction.\n- Add [`WatchRequest.WatchProgressRequest`](https://github.com/etcd-io/etcd/pull/9869).\n  - To manually trigger broadcasting watch progress event (empty watch response with latest header) to all associated watch streams.\n  - Think of it as `WithProgressNotify` that can be triggered manually.\n\nNote: **v3.5 will deprecate `etcd --log-package-levels` flag for `capnslog`**; `etcd --logger=zap --log-outputs=stderr` will the default. **v3.5 will deprecate `[CLIENT-URL]/config/local/log` endpoint.**\n\n### Package `embed`\n\n- Add [`embed.Config.CipherSuites`](https://github.com/etcd-io/etcd/pull/9801) to specify a list of supported cipher suites for TLS handshake between client/server  and peers.\n  - If empty, Go auto-populates the list.\n  - Both `embed.Config.ClientTLSInfo.CipherSuites` and `embed.Config.CipherSuites` cannot be non-empty at the same time.\n  - If not empty, specify either `embed.Config.ClientTLSInfo.CipherSuites` or `embed.Config.CipherSuites`.\n- Add [`embed.Config.InitialElectionTickAdvance`](https://github.com/etcd-io/etcd/pull/9591) to enable/disable initial election tick fast-forward.\n  - `embed.NewConfig()` would return `*embed.Config` with `InitialElectionTickAdvance` as true by default.\n- Define [`embed.CompactorModePeriodic`](https://godoc.org/github.com/etcd-io/etcd/embed#pkg-variables) for `compactor.ModePeriodic`.\n- Define [`embed.CompactorModeRevision`](https://godoc.org/github.com/etcd-io/etcd/embed#pkg-variables) for `compactor.ModeRevision`.\n- Change [`embed.Config.CorsInfo` in `*cors.CORSInfo` type to `embed.Config.CORS` in `map[string]struct{}` type](https://github.com/etcd-io/etcd/pull/9490).\n- Remove [`embed.Config.SetupLogging`](https://github.com/etcd-io/etcd/pull/9572).\n  - Now logger is set up automatically based on [`embed.Config.Logger`, `embed.Config.LogOutputs`, `embed.Config.Debug` fields](https://github.com/etcd-io/etcd/pull/9572).\n- Add [`embed.Config.Logger`](https://github.com/etcd-io/etcd/pull/9518) to support [structured logger `zap`](https://github.com/uber-go/zap) in server-side.\n- Add [`embed.Config.LogLevel`](https://github.com/etcd-io/etcd/pull/10947).\n- Rename `embed.Config.SnapCount` field to [`embed.Config.SnapshotCount`](https://github.com/etcd-io/etcd/pull/9745), to be consistent with the flag name `etcd --snapshot-count`.\n- Rename [**`embed.Config.LogOutput`** to **`embed.Config.LogOutputs`**](https://github.com/etcd-io/etcd/pull/9624) to support multiple log outputs.\n- Change [**`embed.Config.LogOutputs`** type from `string` to `[]string`](https://github.com/etcd-io/etcd/pull/9579) to support multiple log outputs.\n- Add [`embed.Config.BackendBatchLimit`](https://github.com/etcd-io/etcd/pull/10283) field.\n- Add [`embed.Config.BackendBatchInterval`](https://github.com/etcd-io/etcd/pull/10283) field.\n- Make [`embed.DefaultEnableV2` `false` default](https://github.com/etcd-io/etcd/pull/10935).\n\n### Package `pkg/adt`\n\n- Change [`pkg/adt.IntervalTree` from `struct` to `interface`](https://github.com/etcd-io/etcd/pull/10959).\n  - See [`pkg/adt` README](https://github.com/etcd-io/etcd/tree/main/pkg/adt) and [`pkg/adt` godoc](https://godoc.org/go.etcd.io/etcd/pkg/adt).\n- Improve [`pkg/adt.IntervalTree` test coverage](https://github.com/etcd-io/etcd/pull/10959).\n  - See [`pkg/adt` README](https://github.com/etcd-io/etcd/tree/main/pkg/adt) and [`pkg/adt` godoc](https://godoc.org/go.etcd.io/etcd/pkg/adt).\n- Fix [Red-Black tree to maintain black-height property](https://github.com/etcd-io/etcd/pull/10978).\n  - Previously, delete operation violates [black-height property](https://github.com/etcd-io/etcd/issues/10965).\n\n### Package `integration`\n\n- Add [`CLUSTER_DEBUG` to enable test cluster logging](https://github.com/etcd-io/etcd/pull/9678).\n  - Deprecated `capnslog` in integration tests.\n\n### client v3\n\n- Add [`MemberAddAsLearner`](https://github.com/etcd-io/etcd/pull/10725) to `Clientv3.Cluster` interface. This API is used to add a learner member to etcd cluster.\n- Add [`MemberPromote`](https://github.com/etcd-io/etcd/pull/10727) to `Clientv3.Cluster` interface. This API is used to promote a learner member in etcd cluster.\n- Client may receive [`rpctypes.ErrLeaderChanged`](https://github.com/etcd-io/etcd/pull/10094) from server.\n  - Now linearizable requests with read index would fail fast when there is a leadership change, instead of waiting until context timeout.\n- Add [`WithFragment` `OpOption`](https://github.com/etcd-io/etcd/pull/9291) to support [watch events fragmentation](https://github.com/etcd-io/etcd/issues/9294) when the total size of events exceeds `etcd --max-request-bytes` flag value plus gRPC-overhead 512 bytes.\n  - Watch fragmentation is disabled by default.\n  - The default server-side request bytes limit is `embed.DefaultMaxRequestBytes` which is 1.5 MiB plus gRPC-overhead 512 bytes.\n  - If watch response events exceed this server-side request limit and watch request is created with `fragment` field `true`, the server will split watch events into a set of chunks, each of which is a subset of watch events below server-side request limit.\n  - Useful when client-side has limited bandwidths.\n  - For example, watch response contains 10 events, where each event is 1 MiB. And server `etcd --max-request-bytes` flag value is 1 MiB. Then, server will send 10 separate fragmented events to the client.\n  - For example, watch response contains 5 events, where each event is 2 MiB. And server `etcd --max-request-bytes` flag value is 1 MiB and `clientv3.Config.MaxCallRecvMsgSize` is 1 MiB. Then, server will try to send 5 separate fragmented events to the client, and the client will error with `\"code = ResourceExhausted desc = grpc: received message larger than max (...)\"`.\n- Add [`Watcher.RequestProgress` method](https://github.com/etcd-io/etcd/pull/9869).\n  - To manually trigger broadcasting watch progress event (empty watch response with latest header) to all associated watch streams.\n  - Think of it as `WithProgressNotify` that can be triggered manually.\n- Fix [lease keepalive interval updates when response queue is full](https://github.com/etcd-io/etcd/pull/9952).\n  - If `<-chan *clientv3LeaseKeepAliveResponse` from `clientv3.Lease.KeepAlive` was never consumed or channel is full, client was [sending keepalive request every 500ms](https://github.com/etcd-io/etcd/issues/9911) instead of expected rate of every \"TTL / 3\" duration.\n- Change [snapshot file permissions](https://github.com/etcd-io/etcd/pull/9977): On Linux, the snapshot file changes from readable by all (mode 0644) to readable by the user only (mode 0600).\n- Client may choose to send keepalive pings to server using [`PermitWithoutStream`](https://github.com/etcd-io/etcd/pull/10146).\n  - By setting `PermitWithoutStream` to true, client can send keepalive pings to server without any active streams(RPCs). In other words, it allows sending keepalive pings with unary or simple RPC calls.\n  - `PermitWithoutStream` is set to false by default.\n- Fix logic on [release lock key if cancelled](https://github.com/etcd-io/etcd/pull/10153) in `clientv3/concurrency` package.\n- Fix [`(*Client).Endpoints()` method race condition](https://github.com/etcd-io/etcd/pull/10595).\n- Deprecated [`grpc.ErrClientConnClosing`](https://github.com/etcd-io/etcd/pull/10981).\n  - `clientv3` and `proxy/grpcproxy` now does not return `grpc.ErrClientConnClosing`.\n  - `grpc.ErrClientConnClosing` has been [deprecated in gRPC >= 1.10](https://github.com/grpc/grpc-go/pull/1854).\n  - Use `clientv3.IsConnCanceled(error)` or `google.golang.org/grpc/status.FromError(error)` instead.\n\n### etcdctl v3\n\n- Make [`ETCDCTL_API=3 etcdctl` default](https://github.com/etcd-io/etcd/issues/9600).\n  - Now, `etcdctl set foo bar` must be `ETCDCTL_API=2 etcdctl set foo bar`.\n  - Now, `ETCDCTL_API=3 etcdctl put foo bar` could be just `etcdctl put foo bar`.\n- Add [`etcdctl member add --learner` and `etcdctl member promote`](https://github.com/etcd-io/etcd/pull/10725) to add and promote raft learner member in etcd cluster.\n- Add [`etcdctl --password`](https://github.com/etcd-io/etcd/pull/9730) flag.\n  - To support [`:` character in user name](https://github.com/etcd-io/etcd/issues/9691).\n  - e.g. `etcdctl --user user --password password get foo`\n- Add [`etcdctl user add --new-user-password`](https://github.com/etcd-io/etcd/pull/9730) flag.\n- Add [`etcdctl check datascale`](https://github.com/etcd-io/etcd/pull/9185) command.\n- Add [`etcdctl check datascale --auto-compact, --auto-defrag`](https://github.com/etcd-io/etcd/pull/9351) flags.\n- Add [`etcdctl check perf --auto-compact, --auto-defrag`](https://github.com/etcd-io/etcd/pull/9330) flags.\n- Add [`etcdctl defrag --cluster`](https://github.com/etcd-io/etcd/pull/9390) flag.\n- Add [\"raft applied index\" field to `endpoint status`](https://github.com/etcd-io/etcd/pull/9176).\n- Add [\"errors\" field to `endpoint status`](https://github.com/etcd-io/etcd/pull/9206).\n- Add [`etcdctl endpoint health --write-out` support](https://github.com/etcd-io/etcd/pull/9540).\n  - Previously, [`etcdctl endpoint health --write-out json` did not work](https://github.com/etcd-io/etcd/issues/9532).\n- Add [missing newline in `etcdctl endpoint health`](https://github.com/etcd-io/etcd/pull/10793).\n- Fix [`etcdctl watch [key] [range_end] -- [exec-command…]`](https://github.com/etcd-io/etcd/pull/9688) parsing.\n  - Previously,  `ETCDCTL_API=3 etcdctl watch foo -- echo watch event received` panicked.\n- Fix [`etcdctl move-leader` command for TLS-enabled endpoints](https://github.com/etcd-io/etcd/pull/9807).\n- Add [`progress` command to `etcdctl watch --interactive`](https://github.com/etcd-io/etcd/pull/9869).\n  - To manually trigger broadcasting watch progress event (empty watch response with latest header) to all associated watch streams.\n  - Think of it as `WithProgressNotify` that can be triggered manually.\n- Add [timeout](https://github.com/etcd-io/etcd/pull/10301) to `etcdctl snapshot\n  save`.\n  - User can specify timeout of `etcdctl snapshot save` command using flag `--command-timeout`.\n  - Fix etcdctl to [strip out insecure endpoints from DNS SRV records when using discovery](https://github.com/etcd-io/etcd/pull/10443)\n\n### gRPC proxy\n\n- Fix [etcd server panic from restore operation](https://github.com/etcd-io/etcd/pull/9775).\n  - Let's assume that a watcher had been requested with a future revision X and sent to node A that became network-partitioned thereafter. Meanwhile, cluster makes progress. Then when the partition gets removed, the leader sends a snapshot to node A. Previously if the snapshot's latest revision is still lower than the watch revision X,  **etcd server panicked** during snapshot restore operation.\n  - Especially, gRPC proxy was affected, since it detects a leader loss with a key `\"proxy-namespace__lostleader\"` and a watch revision `\"int64(math.MaxInt64 - 2)\"`.\n  - Now, this server-side panic has been fixed.\n- Fix [memory leak in cache layer](https://github.com/etcd-io/etcd/pull/10327).\n- Change [gRPC proxy to expose etcd server endpoint /metrics](https://github.com/etcd-io/etcd/pull/10618).\n  - The metrics that were exposed via the proxy were not etcd server members but instead the proxy itself.\n\n### gRPC gateway\n\n- Replace [gRPC gateway](https://github.com/grpc-ecosystem/grpc-gateway) endpoint `/v3beta` with [`/v3`](https://github.com/etcd-io/etcd/pull/9298).\n  - Deprecated [`/v3alpha`](https://github.com/etcd-io/etcd/pull/9298).\n  - To deprecate [`/v3beta`](https://github.com/etcd-io/etcd/issues/9189) in v3.5.\n  - In v3.4, `curl -L http://localhost:2379/v3beta/kv/put -X POST -d '{\"key\": \"Zm9v\", \"value\": \"YmFy\"}'` still works as a fallback to `curl -L http://localhost:2379/v3/kv/put -X POST -d '{\"key\": \"Zm9v\", \"value\": \"YmFy\"}'`, but `curl -L http://localhost:2379/v3beta/kv/put -X POST -d '{\"key\": \"Zm9v\", \"value\": \"YmFy\"}'` won't work in v3.5. Use `curl -L http://localhost:2379/v3/kv/put -X POST -d '{\"key\": \"Zm9v\", \"value\": \"YmFy\"}'` instead.\n- Add API endpoints [`/{v3beta,v3}/lease/leases, /{v3beta,v3}/lease/revoke, /{v3beta,v3}/lease/timetolive`](https://github.com/etcd-io/etcd/pull/9450).\n  - To deprecate [`/{v3beta,v3}/kv/lease/leases, /{v3beta,v3}/kv/lease/revoke, /{v3beta,v3}/kv/lease/timetolive`](https://github.com/etcd-io/etcd/issues/9430) in v3.5.\n- Support [`etcd --cors`](https://github.com/etcd-io/etcd/pull/9490) in v3 HTTP requests (gRPC gateway).\n\n### Package `raft`\n\n- Fix [deadlock during PreVote migration process](https://github.com/etcd-io/etcd/pull/8525).\n- Add [`raft.ErrProposalDropped`](https://github.com/etcd-io/etcd/pull/9067).\n  - Now [`(r *raft) Step` returns `raft.ErrProposalDropped`](https://github.com/etcd-io/etcd/pull/9137) if a proposal has been ignored.\n  - e.g. a node is removed from cluster, or [`raftpb.MsgProp` arrives at current leader while there is an ongoing leadership transfer](https://github.com/etcd-io/etcd/issues/8975).\n- Improve [Raft `becomeLeader` and `stepLeader`](https://github.com/etcd-io/etcd/pull/9073) by keeping track of latest `pb.EntryConfChange` index.\n  - Previously record `pendingConf` boolean field scanning the entire tail of the log, which can delay heartbeat send.\n- Fix [missing learner nodes on `(n *node) ApplyConfChange`](https://github.com/etcd-io/etcd/pull/9116).\n- Add [`raft.Config.MaxUncommittedEntriesSize`](https://github.com/etcd-io/etcd/pull/10167) to limit the total size of the uncommitted entries in bytes.\n  - Once exceeded, raft returns `raft.ErrProposalDropped` error.\n  - Prevent [unbounded Raft log growth](https://github.com/cockroachdb/cockroach/issues/27772).\n  - There was a bug in [PR#10167](https://github.com/etcd-io/etcd/pull/10167) but fixed via [PR#10199](https://github.com/etcd-io/etcd/pull/10199).\n- Add [`raft.Ready.CommittedEntries` pagination using `raft.Config.MaxSizePerMsg`](https://github.com/etcd-io/etcd/pull/9982).\n  - This prevents out-of-memory errors if the raft log has become very large and commits all at once.\n  - Fix [correctness bug in CommittedEntries pagination](https://github.com/etcd-io/etcd/pull/10063).\n- Optimize [message send flow control](https://github.com/etcd-io/etcd/pull/9985).\n  - Leader now sends more append entries if it has more non-empty entries to send after updating flow control information.\n  - Now, Raft allows multiple in-flight append messages.\n- Optimize [memory allocation when boxing slice in `maybeCommit`](https://github.com/etcd-io/etcd/pull/10679).\n  - By boxing a heap-allocated slice header instead of the slice header on the stack, we can avoid an allocation when passing through the sort.Interface interface.\n- Avoid [memory allocation in Raft entry `String` method](https://github.com/etcd-io/etcd/pull/10680).\n- Avoid [multiple memory allocations when merging stable and unstable log](https://github.com/etcd-io/etcd/pull/10684).\n- Extract [progress tracking into own component](https://github.com/etcd-io/etcd/pull/10683).\n  - Add [package `raft/tracker`](https://github.com/etcd-io/etcd/pull/10807).\n  - Optimize [string representation of `Progress`](https://github.com/etcd-io/etcd/pull/10882).\n- Make [relationship between `node` and `RawNode` explicit](https://github.com/etcd-io/etcd/pull/10803).\n- Prevent [learners from becoming leader](https://github.com/etcd-io/etcd/pull/10822).\n- Add [package `raft/quorum` to reason about committed indexes as well as vote outcomes for both majority and joint quorums](https://github.com/etcd-io/etcd/pull/10779).\n  - Bundle [Voters and Learner into `raft/tracker.Config` struct](https://github.com/etcd-io/etcd/pull/10865).\n- Use [membership sets in progress tracking](https://github.com/etcd-io/etcd/pull/10779).\n- Implement [joint quorum computation](https://github.com/etcd-io/etcd/pull/10779).\n- Refactor [`raft/node.go` to centralize configuration change application](https://github.com/etcd-io/etcd/pull/10865).\n- Allow [voter to become learner through snapshot](https://github.com/etcd-io/etcd/pull/10864).\n- Add [package `raft/confchange` to internally support joint consensus](https://github.com/etcd-io/etcd/pull/10779).\n- Use [`RawNode` for node's event loop](https://github.com/etcd-io/etcd/pull/10892).\n- Add [`RawNode.Bootstrap` method](https://github.com/etcd-io/etcd/pull/10892).\n- Add [`raftpb.ConfChangeV2` to use joint quorums](https://github.com/etcd-io/etcd/pull/10914).\n  - `raftpb.ConfChange` continues to work as today: it allows carrying out a single configuration change. A `pb.ConfChange` proposal gets added to the Raft log as such and is thus also observed by the app during Ready handling, and fed back to ApplyConfChange.\n  - `raftpb.ConfChangeV2` allows joint configuration changes but will continue to carry out configuration changes in \"one phase\" (i.e. without ever entering a joint config) when this is possible.\n  - `raftpb.ConfChangeV2` messages initiate configuration changes. They support both the simple \"one at a time\" membership change protocol and full Joint Consensus allowing for arbitrary changes in membership.\n- Change [`raftpb.ConfState.Nodes` to `raftpb.ConfState.Voters`](https://github.com/etcd-io/etcd/pull/10914).\n- Allow [learners to vote, but still learners do not count in quorum](https://github.com/etcd-io/etcd/pull/10998).\n  - necessary in the situation in which a learner has been promoted (i.e. is now a voter) but has not learned about this yet.\n- Fix [restoring joint consensus](https://github.com/etcd-io/etcd/pull/11003).\n- Visit [`Progress` in stable order](https://github.com/etcd-io/etcd/pull/11004).\n- Proactively [probe newly added followers](https://github.com/etcd-io/etcd/pull/11037).\n  - The general expectation in `tracker.Progress.Next == c.LastIndex` is that the follower has no log at all (and will thus likely need a snapshot), though the app may have applied a snapshot out of band before adding the replica (thus making the first index the better choice).\n  - Previously, when the leader applied a new configuration that added voters, it would not immediately probe these voters, delaying when they would be caught up.\n\n### Package `wal`\n\n- Add [`Verify` function to perform corruption check on WAL contents](https://github.com/etcd-io/etcd/pull/10603).\n- Fix [`wal` directory cleanup on creation failures](https://github.com/etcd-io/etcd/pull/10689).\n\n### Tooling\n\n- Add [`etcd-dump-logs --entry-type`](https://github.com/etcd-io/etcd/pull/9628) flag to support WAL log filtering by entry type.\n- Add [`etcd-dump-logs --stream-decoder`](https://github.com/etcd-io/etcd/pull/9790) flag to support custom decoder.\n- Add [`SHA256SUMS`](https://github.com/etcd-io/etcd/pull/11087) file to release assets.\n  - etcd maintainers are a distributed team, this change allows for releases to be cut and validation provided without requiring a signing key.\n\n### Go\n\n- Require [*Go 1.12+*](https://github.com/etcd-io/etcd/pull/10045).\n- Compile with [*Go 1.12.9*](https://golang.org/doc/devel/release.html#go1.12) including [*Go 1.12.8*](https://groups.google.com/d/msg/golang-announce/65QixT3tcmg/DrFiG6vvCwAJ) security fixes.\n\n### Dockerfile\n\n- [Rebase etcd image from Alpine to Debian](https://github.com/etcd-io/etcd/pull/10805) to improve security and maintenance effort for etcd release.\n\n---\n\n"

guide](https://etcd.io/docs/latest/upgrades/upgrade_3_5/).**\n\n### Breaking Changes\n\n- `go.etcd.io/etcd` Go packages have moved to `go.etcd.io/etcd/{api,pkg,raft,client,etcdctl,server,raft,tests}/v3` to follow the [Go modules](https://github.com/golang/go/wiki/Modules) conventions\n- `go.etcd.io/clientv3/snapshot` SnapshotManager class have moved to `go.etcd.io/clientv3/etcdctl`.\n   The method `snapshot.Save` to download a snapshot from the remote server was preserved in 'go.etcd.io/clientv3/snapshot`.\n- `go.etcd.io/client' package got migrated to 'go.etcd.io/client/v2'.\n- Changed behavior of clientv3 API [MemberList](https://github.com/etcd-io/etcd/pull/11639).\n  - Previously, it is directly served with server's local data, which could be stale.\n  - Now, it is served with linearizable guarantee. If the server is disconnected from quorum, `MemberList` call will fail.\n- [gRPC gateway](https://github.com/grpc-ecosystem/grpc-gateway) only supports [`/v3`](TODO) endpoint.\n  - Deprecated [`/v3beta`](https://github.com/etcd-io/etcd/pull/9298).\n  - `curl -L http://localhost:2379/v3beta/kv/put -X POST -d '{\"key\": \"Zm9v\", \"value\": \"YmFy\"}'` doesn't work in v3.5. Use `curl -L http://localhost:2379/v3/kv/put -X POST -d '{\"key\": \"Zm9v\", \"value\": \"YmFy\"}'` instead.\n- **`etcd --experimental-enable-v2v3` flag remains experimental and to be deprecated.**\n  - v2 storage emulation feature will be deprecated in the next release.\n  - etcd 3.5 is the last version that supports V2 API. Flags `--enable-v2` and `--experimental-enable-v2v3` [are now deprecated](https://github.com/etcd-io/etcd/pull/12940) and will be removed in etcd v3.6 release.\n- **`etcd --experimental-backend-bbolt-freelist-type` flag has been deprecated.** Use **`etcd --backend-bbolt-freelist-type`** instead. The default type is hashmap and it is stable now.\n- **`etcd --debug` flag has been deprecated.** Use **`etcd --log-level=debug`** instead.\n- Remove [`embed.Config.Debug`](https://github.com/etcd-io/etcd/pull/10947).\n- **`etcd --log-output` flag has been deprecated.** Use **`etcd --log-outputs`** instead.\n- **`etcd --logger=zap --log-outputs=stderr`** is now the default.\n- **`etcd --logger=capnslog` flag value has been deprecated.**\n- **`etcd --logger=zap --log-outputs=default` flag value is not supported.**.\n  - Use `etcd --logger=zap --log-outputs=stderr`.\n  - Or, use `etcd --logger=zap --log-outputs=systemd/journal` to send logs to the local systemd journal.\n  - Previously, if etcd parent process ID (PPID) is 1 (e.g. run with systemd), `etcd --logger=capnslog --log-outputs=default` redirects server logs to local systemd journal. And if write to journald fails, it writes to `os.Stderr` as a fallback.\n  - However, even with PPID 1, it can fail to dial systemd journal (e.g. run embedded etcd with Docker container). Then, [every single log write will fail](https://github.com/etcd-io/etcd/pull/9729) and fall back to `os.Stderr`, which is inefficient.\n  - To avoid this problem, systemd journal logging must be configured manually.\n- **`etcd --log-outputs=stderr`** is now the default.\n- **`etcd --log-package-levels` flag for `capnslog` has been deprecated.** Now, **`etcd --logger=zap --log-outputs=stderr`** is the default.\n- **`[CLIENT-URL]/config/local/log` endpoint has been deprecated, as is `etcd --log-package-levels` flag.**\n  - `curl http://127.0.0.1:2379/config/local/log -XPUT -d '{\"Level\":\"DEBUG\"}'` won't work.\n  - Please use `etcd --logger=zap --log-outputs=stderr` instead.\n- Deprecated `etcd_debugging_mvcc_db_total_size_in_bytes` Prometheus metric. Use `etcd_mvcc_db_total_size_in_bytes` instead.\n- Deprecated `etcd_debugging_mvcc_put_total` Prometheus metric. Use `etcd_mvcc_put_total` instead.\n- Deprecated `etcd_debugging_mvcc_delete_total` Prometheus metric.

Each patch release only includes changes against previous patch release.\nFor example, the change log of v3.5.5 should only include items which are new to v3.5.4.\n2. For the first release (e.g. 3.4.0, 3.5.0, 3.6.0, 4.0.0 etc.) for each minor or major \nversion, it only includes changes which are new to the first release of previous minor\nor major version.

[These](https://github.com/etcd-io/etcd/issues?q=is%3Aissue+is%3Aopen+label%3Atype%2Fflake) are the currently open flaky test issues.\n\nFor more, because etcd uses Kubernetes' prow infrastructure to run CI jobs, the past test results can be viewed at [testgrid](https://testgrid.k8s.io/sig-etcd).\n\n| Tests  | Status  |\n| -----  | ------  |\n| periodics e2e-amd64  | [![sig-etcd-periodics/ci-etcd-e2e-amd64](https://testgrid.k8s.io/q/summary/sig-etcd-periodics/ci-etcd-e2e-amd64/tests_status?style=svg)](https://testgrid.k8s.io/q/summary/sig-etcd-periodics/ci-etcd-e2e-amd64)  |\n| presubmit build      | [![sig-etcd-presubmits/pull-etcd-build](https://testgrid.k8s.io/q/summary/sig-etcd-presubmits/pull-etcd-build/tests_status?style=svg)](https://testgrid.k8s.io/q/summary/sig-etcd-presubmits/pull-etcd-build)  |\n| presubmit e2e-amd64  | [![sig-etcd-presubmits/pull-etcd-e2e-amd64](https://testgrid.k8s.io/q/summary/sig-etcd-presubmits/pull-etcd-e2e-amd64/tests_status?style=svg)](https://testgrid.k8s.io/q/summary/sig-etcd-presubmits/pull-etcd-e2e-amd64)  |\n| presubmit unit-test-amd64  | [![sig-etcd-presubmits/pull-etcd-unit-test-amd64](https://testgrid.k8s.io/q/summary/sig-etcd-presubmits/pull-etcd-unit-test-amd64/tests_status?style=svg)](https://testgrid.k8s.io/q/summary/sig-etcd-presubmits/pull-etcd-unit-test-amd64)  |\n| presubmit verify     | [![sig-etcd-presubmits/pull-etcd-verify](https://testgrid.k8s.io/q/summary/sig-etcd-presubmits/pull-etcd-verify/tests_status?style=svg)](https://testgrid.k8s.io/q/summary/sig-etcd-presubmits/pull-etcd-verify)  |\n| postsubmit build     | [![sig-etcd-postsubmits/post-etcd-build](https://testgrid.k8s.io/q/summary/sig-etcd-postsubmits/post-etcd-build/tests_status?style=svg)](https://testgrid.k8s.io/q/summary/sig-etcd-postsubmits/post-etcd-build)  |\n\nIf you find any flaky tests on testgrid, please\n\n1. Check [existing issues](https://github.com/etcd-io/etcd/issues?q=is%3Aissue+is%3Aopen+label%3Atype%2Fflake) to see if an issue has already been opened for this test. If not, open an issue with the `type/flake` label.\n2. Try to reproduce the flaky test on your machine via [`stress`](https://pkg.go.dev/golang.org/x/tools/cmd/stress), for example, to reproduce the failure of `TestPeriodicSkipRevNotChange`:\n\n```bash\n# install the stress utility\ngo install golang.org/x/tools/cmd/stress@latest\ncd server/etcdserver/api/v3compactor\n# compile the test\ngo test -v -c -count 1\n# run the compiled test file using stress\nstress -p=8 ./v3compactor.test -test.run “^TestPeriodicSkipRevNotChange$”\n```\n3. Fix it.\n\n## Set up development environment\n\nThe etcd project supports two options for development:\n\n 1. Manually set up the local environment.\n 2. Automatically set up [devcontainer](https://containers.dev).\n\nFor both options, the only supported architecture is `linux-amd64`. Bug reports for other environments will generally be ignored. Supporting new environments requires the introduction of proper tests and maintainer support that is currently lacking in the etcd project.\n\nIf you would like etcd to support your preferred environment you can [file an issue].\n\n### Option 1 - Manually set up the local environment\n\nThis is the original etcd development environment, is most supported, and is backward compatible for the development of older etcd versions.\n\nFollow the steps below to set up the environment:\n\n- [Clone the repository](https://docs.github.com/en/repositories/creating-and-managing-repositories/cloning-a-repository)\n- Install Go by following [installation](https://go.dev/doc/install). Please check the minimal go version in [go.mod file](./go.mod#L3).\n- Install build tools:\n  - [`make`](https://www.gnu.org/software/make/): For Debian-based distributions\n    you can run `sudo apt-get install build-essential`\n  - [`protoc`](https://protobuf.dev/): You can download it for your os. Use\n    version\n    [`v3.20.3`](https://github.com/protocolbuffers/protobuf/releases/tag/v3.20.3).\n  - [`yamllint`](https://www.yamllint.com/): For Debian-based distribution you\n    can run `sudo apt-get install yamllint`\n  - [`jq`](https://jqlang.github.io/jq/): For Debian-based distribution you can\n    run `sudo apt-get install jq`\n  - [`xz`](https://tukaani.org/xz/): For Debian-based distribution you can run\n    `sudo apt-get install xz-utils`\n- Verify that everything is installed by running `make build`\n\nNote: `make build` runs with `-v`. Other build flags can be added through env `GO_BUILD_FLAGS`, **if required**. Eg.,\n```console\nGO_BUILD_FLAGS=\"-buildmode=pie\" make build\n```\n\n### Option 2 - Automatically set up devcontainer\n\nThis is a more recently added environment that aims to make it faster for new contributors to get started with etcd. This option is supported for etcd versions 3.6 onwards.\n\nThis option can be [used locally](https://code.visualstudio.com/docs/devcontainers/tutorial) on a system running Visual Studio Code and Docker, or in a remote cloud-based [Codespaces](https://github.com/features/codespaces) environment.\n\nTo get started, create a codespace for this repository by clicking this 👇\n\n[![Open in GitHub Codespaces](https://github.com/codespaces/badge.svg)](https://github.com/codespaces/new?hide_repo_select=true&ref=main&repo=11225014)\n\nA codespace will open in a web-based version of Visual Studio Code. The [dev container](.devcontainer/devcontainer.json) is fully configured with the software needed for this project.\n\n**Note**: Dev containers is an open spec which is supported by [GitHub Codespaces](https://github.com/codespaces) and [other tools](https://containers.dev/supporting).\n\n[file an issue]: https://github.com/etcd-io/etcd/issues/new/choose\n\n## Implement your change\n\netcd code should follow the coding style suggested by the Golang community.\nSee the [style doc](https://go.dev/wiki/CodeReviewComments) for details.\n\nPlease ensure that your change passes static analysis (requires\n[golangci-lint](https://golangci-lint.run/welcome/install/)):\n- `make verify` to verify if all checks pass.\n- `make verify-*` to verify a single check, for example, `make verify-bom` to verify if `bill-of-materials.json` file is up-to-date.\n- `make fix` to fix all checks.\n- `make fix-*` to fix a single check, for example, `make fix-bom` to update `bill-of-materials.json`.\n\nPlease ensure that your change passes tests.\n- `make test-unit` to run unit tests.\n- `make test-integration` to run integration tests.\n- `make test-e2e` to run e2e tests.\n\nAll changes are expected to come with a unit test.\nAll new features are expected to have either e2e or integration tests.\n\n## Commit your change\n\netcd follows a rough convention for commit messages:\n* First line:\n  * Should start with the name of the package (for example `etcdserver`, `etcdctl`) followed by the `:` character.\n  * Describe the `what` behind the change\n* Optionally, the author might provide the `why` behind the change in the main commit message body.\n* Last line should be `Signed-off-by: firstname lastname <email@example.com>` (can be automatically generate by providing `--signoff` to git commit command).\n\nExample of commit message:\n```\netcdserver: add grpc interceptor to log info on incoming requests\n\nTo improve debuggability of etcd v3. Added a grpc interceptor to log\ninfo on incoming requests to etcd server. The log output includes\nremote client info, request content (with value field redacted), request\nhandling latency, response size, etc. Uses zap logger if available,\notherwise uses capnslog.\n\nSigned-off-by: FirstName LastName <github@github.com>\n```\n\n## Create a pull request\n\nPlease follow the [making a pull request](https://docs.github.com/en/get-started/quickstart/contributing-to-projects#making-a-pull-request) guide.\n\nIf you are still working on the pull request, you can convert it to a draft by clicking `Convert to draft` link just below the list of reviewers.\n\nMultiple small PRs are preferred over single large ones (>500 lines of code).\n\nPlease make sure there is an associated issue for each PR you submit. Create one if it doesn't exist yet, and close the issue\nonce the PR gets merged and has been backported to previous stable releases, if necessary. If there are multiple PRs linked to\nthe same issue, refrain from closing the issue until all PRs have been merged and, if needed, backported to previous stable\nreleases.\n\n## Get your pull request reviewed\n\nBefore requesting review please ensure that all GitHub and Prow checks are successful. In some cases your pull request may have the label `needs-ok-to-test`. If so an `etcd-io` organisation member will leave a comment on your pull request with `/ok-to-test` to trigger all checks to be run.\n\nIt might happen that some unrelated tests on your PR are failing, due to their flakiness.\nIn such cases please [file an issue] to deflake the problematic test and ask one of [maintainers] to rerun the tests.\n\nIf all checks were successful feel free to reach out for review from people that were involved in the original discussion or [maintainers].\nDepending on the complexity of the PR it might require between 1 and 2 maintainers to approve your change before merging.\n\nThanks for contributing!\n"

All new features land here first.\n\nTo try new and experimental features, pull `main` and play with it. Note that `main` may not be stable because new features may introduce bugs.\n\nBefore the release of the next stable version, feature PRs will be frozen. A [release manager](./release.md#release-management) will be assigned to the major/minor version and will lead the etcd community in testing, bug-fix, and documentation of the release for one to two weeks.\n\n### Stable branches\n\nAll branches with the prefix `release-` are considered _stable_ branches.\n\nAfter every minor release ([semver.org](https://semver.org/)), we will have a new stable branch for that release, managed by a [patch release manager](./release.md#release-management). We will keep fixing the backward-compatible bugs for the latest two stable releases. A _patch_ release to each supported release branch, incorporating any bug fixes, will be once every two weeks, given any patches.\n\n[main]: https://github.com/etcd-io/etcd/tree/main\n"

Get all the etcd modules used in Kubernetes.\n\n    ```bash\n    $ grep 'go.etcd.io/etcd/' go.mod | awk '{print $1}'\n    go.etcd.io/etcd/api/v3\n    go.etcd.io/etcd/client/pkg/v3\n    go.etcd.io/etcd/client/v3\n    go.etcd.io/etcd/client/v2\n    go.etcd.io/etcd/pkg/v3\n    go.etcd.io/etcd/raft/v3\n    go.etcd.io/etcd/server/v3\n    ```\n\n2. For each module, in the root directory of the `kubernetes/kubernetes` repository, fetch the new version in `go.mod` using the following command (using `client/v3` as an example):\n\n    ```bash\n    hack/pin-dependency.sh go.etcd.io/etcd/client/v3 NEW_VERSION\n    ```\n\n3. Rebuild the `vendor` directory and update the `go.mod` files for all staging repositories using the command below. This automatically updates the licenses.\n\n    ```bash\n    hack/update-vendor.sh\n    ```\n\n4. Check if the new dependency requires newer versions of existing dependencies we have pinned. You can check this by:\n\n    * Running `hack/lint-dependencies.sh` against your branch and against `master` and comparing the results.\n    * Checking if any new `replace` directives were added to `go.mod` files of components inside the staging directory.\n\n## Bump etcd image\n\n### Build etcd image\n\n> Reference: [link 1](https://github.com/kubernetes/kubernetes/pull/131105) [link 2](https://github.com/kubernetes/kubernetes/pull/131126)\n\n1.

Update `golang: etcd release version` if necessary.\n\n    ```yaml\n    - name: \"etcd-image\"\n      # version: 3.5.17\n      version: 3.5.21\n      refPaths:\n      - path: cluster/images/etcd/Makefile\n        match: BUNDLED_ETCD_VERSIONS\\?|\n    ---\n    - name: \"golang: etcd release version\"\n      # version: 1.22.9\n      version: 1.23.7 # https://github.com/etcd-io/etcd/blob/main/CHANGELOG/CHANGELOG-3.6.md\n    ```\n\n2. In `cluster/images/etcd/Makefile`, include the new version in `BUNDLED_ETCD_VERSIONS` and update the `LATEST_ETCD_VERSION` as well (the image tag will be generated from the `LATEST_ETCD_VERSION`). Update `GOLANG_VERSION` according to the version used to compile that release version (`\"golang: etcd release version\"` in step 1).\n\n    ```Makefile\n    # BUNDLED_ETCD_VERSIONS?=3.4.18 3.5.17\n    BUNDLED_ETCD_VERSIONS?=3.4.18 3.5.21\n\n    # LATEST_ETCD_VERSION?=3.5.17\n    LATEST_ETCD_VERSION?=3.5.21\n\n    # GOLANG_VERSION := 1.22.9\n    GOLANG_VERSION := 1.23.7\n    ```\n\n3.

But dependabot doesn't work well for multi-module repository like `etcd`,\nsee [dependabot-core/issues/6678](https://github.com/dependabot/dependabot-core/issues/6678).\nUsually, human intervention is required each time when dependabot automatically opens some PRs to bump dependencies.\nPlease see the guidance below.\n\n### Dependencies used in workflows\n\nThe PRs that automatically bump dependencies (see examples below) used in workflows are fine and can be approved & merged directly as long as all checks are successful.\n\n- [build(deps): bump github/codeql-action from 2.2.11 to 2.2.12](https://github.com/etcd-io/etcd/pull/15736)\n- [build(deps): bump actions/checkout from 3.5.0 to 3.5.2](https://github.com/etcd-io/etcd/pull/15735)\n- [build(deps): bump ossf/scorecard-action from 2.1.2 to 2.1.3](https://github.com/etcd-io/etcd/pull/15607)\n\n### Bumping order\n\nWhen multiple etcd modules depend on the same package, please bump the package version for all the modules in the correct order. The rule is simple:\nif module A depends on module B, then bump the dependency for module B before module A. If the two modules do not depend on each other, then\nit doesn't matter to bump which module first. For example, multiple modules depend on `github.com/spf13/cobra`, so we need to bump the dependency\nin the following order,\n\n- go.etcd.io/etcd/pkg/v3\n- go.etcd.io/etcd/server/v3\n- go.etcd.io/etcd/etcdctl/v3\n- go.etcd.io/etcd/etcdutl/v3\n- go.etcd.io/etcd/tests/v3\n- go.etcd.io/etcd/v3\n- go.etcd.io/etcd/tools/v3\nFor more details about etcd Golang modules, please check <https://etcd.io/docs/next/dev-internal/modules>\n\nNote the module `go.etcd.io/etcd/tools/v3` doesn't depend on any other modules, nor by any other modules, so it doesn't matter when to bump dependencies for it.\n\n### Steps to bump a dependency\n\nUse the `github.com/spf13/cobra` as an example, follow the steps below to bump it from 1.6.1 to 1.7.0 for module `go.etcd.io/etcd/etcdctl/v3`,\n\n```bash\ncd ${ETCD_ROOT_DIR}/etcdctl\ngo get github.com/spf13/cobra@v1.7.0\ngo mod tidy\ncd ..\nmake fix # This will update the bill of materials, Go modules and workspace, etc.\n```\n\nExecute the same steps for all other modules. When you finish bumping the dependency for all modules, then commit the change,\n\n```bash\ngit add .\ngit commit --signoff -m \"dependency: bump github.com/spf13/cobra from 1.6.1 to 1.7.0\"\n```\n\nPlease close the related PRs which were automatically opened by dependabot. \n\nWhen you bump multiple dependencies in one PR, it's recommended to create a separate commit for each dependency. But it isn't a must; for example,\nyou can get all dependencies bumping for the module `go.etcd.io/etcd/tools/v3` included in one commit.\n\n#### Alternative: Using the update_dep.sh script\n\n> Note: Please use bash shell version 5.x or higher.\n\nAs an alternative to the manual steps above, you can use the `update_dep.sh` script to automate the dependency bump process across all modules:\n\n```bash\n# Update to a specific version\n./scripts/update_dep.sh github.com/spf13/cobra v1.7.0\n\n# Update to the latest version\n./scripts/update_dep.sh github.com/spf13/cobra\n```\n\nThe script will:\n\n1. Display the current version of the dependency across all go.mod files\n2. Warn and prompt for confirmation if the dependency is purely indirect\n3. Update the dependency in all modules that depend on it\n4. Run `make fix verify-dep` to ensure consistency across all modules\n5. Display the updated versions for verification\n\nThis script handles the correct bumping order automatically and ensures version consistency across all modules.\n\n#### Troubleshooting\n\nIn an event of bumping the version of protoc, protoc plugins or grpc-gateway, it might change `*.proto` file which can result in the following error:\n\n```bash\n[0;31mFAIL: 'genproto' FAILED at Wed Jul 31 07:09:08 UTC 2024\nmake: *** [Makefile:134: verify-genproto] Error 255\n```\n\nTo fix the above error, run the following script from the root of etcd repository:\n\n```bash\n./scripts/genproto.sh\n```\n\n### Indirect dependencies\n\nUsually, we don't bump a dependency if all modules just indirectly depend on it, such as `github.com/go-logr/logr`.\n\nIf an indirect dependency (e.g. `D1`) causes any CVE or bugs that affect etcd, usually the module (e.g. `M1`, not part of etcd, but used by etcd)\nwhich depends on it should bump the dependency (`D1`), and then etcd just needs to bump `M1`. However, if the module (`M1`) somehow doesn't\nbump the problematic dependency, then etcd can still bump it (`D1`) directly following the same steps above. But as a long-term solution, etcd should\ntry to remove the dependency on such module (`M1`) that lack maintenance.\n\nFor mixed cases, in which some modules directly while others indirectly depend on a dependency, we have multiple options,\n\n- Bump the dependency for all modules, no matter it's direct or indirect dependency.\n- Bump the dependency only for modules that directly depend on it.\n\nWe should try to follow the first way, and temporarily fall back to the second one if we run into any issue on the first way. Eventually we\nshould fix the issue and ensure all modules depend on the same version of the dependency.\n\n### Known incompatible dependency updates\n\n#### arduino/setup-protoc\n\nPlease refer to [build(deps): bump arduino/setup-protoc from 1.3.0 to 2.0.0](https://github.com/etcd-io/etcd/pull/16016)\n\n### Rotation worksheet\n\nThe dependabot scheduling interval is weekly; it means dependabot will automatically raise a bunch of PRs per week.\nUsually, human intervention is required each time. We have a [rotation worksheet](https://docs.google.com/spreadsheets/d/1jodHIO7Dk2VWTs1IRnfMFaRktS9IH8XRyifOnPdSY8I/edit#gid=1394774387),\nand everyone is welcome to participate; you just need to register your name in the worksheet.\n\n## Stable branches\n\nUsually, we don't proactively bump dependencies for stable releases unless there are any CVEs or bugs that affect etcd.\n\nIf we have to do it, then follow the same guidance above. Note that there is no `./scripts/fix.sh`/`make fix` in release-3.4, so no need to\nexecute it for 3.4.\n\n## Golang versions\n\nFor all libraries that exist as independent subprojects (e.g., bbolt, raft, gofail), we should always stick\nto the oldest supported Go minor version for all branches, including main. It's up to the users of these\nlibraries to choose which [Go version](https://go.dev/dl) they want to use in their own projects.\n\nFor other subprojects that produce binaries or images (e.g. etcd, etcd-operator, auger), the main\nbranches should use the latest Go minor version for development, while stable releases should use the\nlatest patch of the previous supported Go minor version to ensure stability.\n\nSuggested steps for performing a minor version upgrade for the etcd development branch:\n\n1. Carefully review new Go version release notes and potentially related blog posts for any deprecations, performance impacts, or other considerations.\n2. Create a GitHub issue to signal intent to upgrade and invite discussion, for example, <https://github.com/etcd-io/etcd/issues/16393>.\n3. Complete the upgrade locally in your development environment by editing `.go-version` and running `make fix`.\n4. Run performance benchmarks locally to compare before and after.\n5. Raise a pull request for the changes, for example, <https://github.com/etcd-io/etcd/pull/16394>.\n\nStable etcd release branches will be maintained to stay on the latest patch release of a supported Go version. Upgrading minor versions will be completed before the minor version in use currently is no longer supported. Refer to the [Go release policy](https://go.dev/doc/devel/release).\n\nFor an example of how to update etcd to a new patch release of Go refer to issue <https://github.com/etcd-io/etcd/issues/16343> and the linked pull requests.\n\nReferences:\n\n- <https://github.com/kubernetes/sig-release/blob/master/release-engineering/handbooks/go.md>\n\n## Core dependencies mappings\n\n[bbolt](https://github.com/etcd-io/bbolt) and [raft](https://github.com/etcd-io/raft) are two core dependencies of etcd.\n\nBoth etcd 3.4.x and 3.5.x depend on bbolt 1.3.x, and etcd 3.6.x depends on bbolt 1.4.x.\n\nraft is included in the etcd repository for release-3.4 and release-3.5 branches, so etcd 3.4.x and 3.5.x do not depend on any\nexternal raft module. We moved raft into [a separate repository](https://github.com/etcd-io/raft) starting from 3.6, and the first raft\nrelease is v3.6.0, so etcd 3.6.0 depends on raft v3.6.0.\n\nPlease see the table below:\n\n| etcd versions | bbolt versions | raft versions |\n|---------------|----------------|---------------|\n| 3.4.x         | v1.3.x         | N/A           |\n| 3.5.x         | v1.3.x         | N/A           |\n| 3.6.x         | v1.4.x         | v3.6.x        |\n"

    "content": "# Features \n\nThis document provides an overview of etcd features and general development guidelines for adding and deprecating them. The project maintainers can override these guidelines per the need of the project following the project governance.\n\n## Overview\n\nThe etcd features fall into three stages: Alpha, Beta, and GA.\n\n### Alpha\n\nAny new feature is usually added as an Alpha feature. An Alpha feature is characterized as below:\n- Might be buggy due to a lack of user testing. Enabling the feature may not work as expected.\n- Disabled by default.\n- Support for such a feature may be dropped at any time without notice\n    - Feature-related issues may be given lower priorities.\n    - It can be removed in the next minor or major release without following the feature deprecation policy unless it graduates to a more stable stage.\n\n### Beta\n\nA Beta feature is characterized as below:\n- Supported as part of the supported releases of etcd.\n- Enabled by default.\n- Discontinuation of support must follow the feature deprecation policy.\n\n### GA\n\nA GA feature is characterized as below:\n- Supported as part of the supported releases of etcd.\n- Always enabled; you cannot disable it. The corresponding feature gate is no longer needed.\n- Discontinuation of support must follow the feature deprecation policy.\n\n## Development Guidelines\n\n### Adding a new feature\n\nAny new enhancements to the etcd are typically added as an Alpha feature. \n\netcd follows the Kubernetes [KEP process](https://github.com/kubernetes/enhancements/blob/master/keps/sig-architecture/0000-kep-process/README.md) for new enhancements. The general development requirements are listed below. They can be somewhat flexible depending on the scope of the feature and review discussions and will evolve over time.\n- Open a [KEP](https://github.com/kubernetes/enhancements/issues) issue\n    - It must provide a clear need for the proposed feature.\n    - It should list development work items as checkboxes. There must be one work item towards future graduation to Beta.\n    - Label the issue with `/sig etcd`.\n    - Keep the issue open for tracking purposes until a decision is made on graduation.\n- Open a [KEP](https://github.com/kubernetes/enhancements) Pull Request (PR). \n    - The KEP template can be simplified for etcd.\n    - It must provide clear graduation criteria for each stage.\n    - The KEP doc should reside in [keps/sig-etcd](https://github.com/kubernetes/enhancements/tree/master/keps/sig-etcd/)\n- Open Pull Requests (PRs) in [etcd](https://github.com/etcd-io/etcd)\n    - Provide unit tests. Integration tests are also recommended as possible.\n    - Provide robust e2e test coverage. If the feature being added is complicated or quickly needed, maintainers can decide to go with e2e tests for basic coverage initially and have robust coverage added at a later time before the feature graduation to the stable feature.\n    - Provide logs for proper debugging.\n    - Provide metrics and benchmarks as needed.\n    - Add an Alpha [feature gate](https://etcd.io/docs/v3.6/feature-gates/).\n    - Any code changes or configuration flags related to the implementation of the feature must be gated with the feature gate e.g. `if cfg.ServerFeatureGate.Enabled(features.FeatureName)`.\n    - Add a CHANGELOG entry.\n- At least two maintainers must approve the KEP and related code changes.\n\n### Graduating a feature to the next stage\n\nIt is important that features don't get stuck in one stage. They should be revisited and moved to the next stage once they meet the graduation criteria listed in the KEP. A feature should stay at one stage for at least one release before being promoted.\n\n#### Provide implementation\n\nIf a feature is found ready for graduation to the next stage, open a Pull Request (PR) with the following changes.\n- Update the feature `PreRelease` stage in `server/features/etcd_features.go`.\n- Update the status in the original KEP issue.\n\nAt least two maintainers must approve the work. Patch releases should not be considered for graduation.\n\n### Deprecating a feature\n\n#### Alpha\nAlpha features can be removed without going through the deprecation process.\n- Remove the feature gate in `server/features/etcd_features.go`, and clean up all relevant code.\n- Close the original KEP issue with reasons to drop the feature.\n\n#### Beta and GA\nAs the project evolves, a Beta/GA feature may sometimes need to be deprecated and removed. Such a situation should be handled using the steps below:\n\n- A Beta/GA feature can only be deprecated after at least 2 minor or major releases.\n- Update original KEP issue if it has not been closed or create a new etcd issue with reasons and steps to deprecate the feature.\n- Add the feature deprecation documentation in the release notes and feature gates documentation of the next minor/major release.\n- In the next minor/major release, set the feature gate to `{Default: false, PreRelease: featuregate.Deprecated, LockedToDefault: false}` in `server/features/etcd_features.go`. Deprecated feature gates must respond with a warning when used.\n    - If the feature has GAed, and the original gated codes has been cleaned up, add the disablement codes back with the feature gate.\n- In the minor/major release after the next, set the feature gate to `{Default: false, PreRelease: featuregate.Deprecated, LockedToDefault: true}` in `server/features/etcd_features.go`, and start cleaning the code.\n\nAt least two maintainers must approve the work. Patch releases should not be considered for deprecation.\n"

    "content": "# Set up the local cluster\n\nFor testing and development deployments, the quickest and easiest way is to configure a local cluster. For a production deployment, refer to the [clustering][clustering] section.\n\n## Local standalone cluster\n\n### Starting a cluster\n\nRun the following to deploy an etcd cluster as a standalone cluster:\n\n```\n$ ./etcd\n...\n```\n\nIf the `etcd` binary is not present in the current working directory, it might be located either at `$GOPATH/bin/etcd` or at `/usr/local/bin/etcd`. Run the command appropriately.\n\nThe running etcd member listens on `localhost:2379` for client requests.\n\n### Interacting with the cluster\n\nUse `etcdctl` to interact with the running cluster:\n\n1. Store an example key-value pair in the cluster:\n\n    ```\n      $ ./etcdctl put foo bar\n      OK\n    ```\n\n    If OK is printed, storing the key-value pair is successful.\n\n2. Retrieve the value of `foo`:\n\n    ```\n    $ ./etcdctl get foo\n    bar\n    ```\n\n    If `bar` is returned, interaction with the etcd cluster is working as expected.\n\n## Local multi-member cluster\n\n### Starting a cluster\n\nA `Procfile` at the base of the etcd git repository is provided to easily configure a local multi-member cluster. To start a multi-member cluster, navigate to the root of the etcd source tree and perform the following:\n\n1. Install `goreman` to control Procfile-based applications:\n\n    ```\n    $ go install github.com/mattn/goreman@latest\n    ```\n   The installation will place executables in the $GOPATH/bin. If $GOPATH environment variable is not set, the tool will be installed into the $HOME/go/bin. Make sure that $PATH is set accordingly in your environment.\n\n2. Start a cluster with `goreman` using etcd's stock Procfile:\n\n    ```\n    $ goreman -f Procfile start\n    ```\n\n    The members start running. They listen on `localhost:2379`, `localhost:22379`, and `localhost:32379` respectively for client requests.\n\n### Interacting with the cluster\n\nUse `etcdctl` to interact with the running cluster:\n\n1. Print the list of members:\n\n    ```\n    $ etcdctl --write-out=table --endpoints=localhost:2379 member list\n    ```\n    The list of etcd members is displayed as follows:\n\n    ```\n    +------------------+---------+--------+------------------------+------------------------+\n    |        ID        | STATUS  |  NAME  |       PEER ADDRS       |      CLIENT ADDRS      |\n    +------------------+---------+--------+------------------------+------------------------+\n    | 8211f1d0f64f3269 | started | infra1 | http://127.0.0.1:2380  | http://127.0.0.1:2379  |\n    | 91bc3c398fb3c146 | started | infra2 | http://127.0.0.1:22380 | http://127.0.0.1:22379 |\n    | fd422379fda50e48 | started | infra3 | http://127.0.0.1:32380 | http://127.0.0.1:32379 |\n    +------------------+---------+--------+------------------------+------------------------+\n    ```\n\n2. Store an example key-value pair in the cluster:\n\n    ```\n    $ etcdctl put foo bar\n    OK\n    ```\n\n    If OK is printed, storing the key-value pair is successful.\n\n### Testing fault tolerance\n\nTo exercise etcd's fault tolerance, kill a member and attempt to retrieve the key.\n\n1. Identify the process name of the member to be stopped.\n\n    The `Procfile` lists the properties of the multi-member cluster. For example, consider the member with the process name, `etcd2`.\n\n2. Stop the member:\n\n    ```\n    # kill etcd2\n    $ goreman run stop etcd2\n    ```\n\n3. Store a key:\n\n    ```\n    $ etcdctl put key hello\n    OK\n    ```\n\n4.  Retrieve the key that is stored in the previous step:\n\n    ```\n    $ etcdctl get key\n    hello\n    ```\n\n5. Retrieve a key from the stopped member:\n\n    ```\n    $ etcdctl --endpoints=localhost:22379 get key\n    ```\n\n    The command should display an error caused by connection failure:\n\n    ```\n    2017/06/18 23:07:35 grpc: Conn.resetTransport failed to create client transport: connection error: desc = \"transport: dial tcp 127.0.0.1:22379: getsockopt: connection refused\"; Reconnecting to \"localhost:22379\"\n    Error:  grpc: timed out trying to connect\n    ```\n6. Restart the stopped member:\n\n    ```\n    $ goreman run restart etcd2\n    ```\n\n7. Get the key from the restarted member:\n\n    ```\n    $ etcdctl --endpoints=localhost:22379 get key\n    hello\n    ```\n\n    Restarting the member re-establishs the connection. `etcdctl` will now be able to retrieve the key successfully.

A package belongs here\n  only if it could possibly be moved out into its own repository in the future.\n  Please avoid adding here code that has a lot of dependencies on its own, as\n  they automatically become dependencies of the client library\n  (that we want to keep lightweight).\n\n  - **go.etcd.io/etcd/client/v3** - client library used to contact etcd over\n  the network (grpc). Recommended for all new usage of etcd.\n\n  - **go.etcd.io/raft/v3** - implementation of distributed consensus\n  protocol. Should have no etcd specific code. Hosted in a separate repository:\n  https://github.com/etcd-io/raft.\n\n  - **go.etcd.io/etcd/server/v3** - etcd implementation.\n  The code in this package is internal to etcd and should not be consumed\n  by external projects. The package layout and API can change within the minor versions.\n\n  - **go.etcd.io/etcd/etcdctl/v3** - a command line tool to access and manage etcd.\n\n  - **go.etcd.io/etcd/tests/v3** - a module that contains all integration tests of etcd.\n    Notice: All unit tests (fast and not requiring cross-module dependencies)\n    should be kept in the local modules of the code under the test.\n\n  - **go.etcd.io/bbolt** - implementation of persistent b-tree.\n    Hosted in a separate repository: https://github.com/etcd-io/bbolt.\n\n\n### Operations\n\n1. All etcd modules should be released in the same versions, e.g.\n   `go.etcd.io/etcd/client/v3@v3.5.10` must depend on `go.etcd.io/etcd/api/v3@v3.5.10`.\n\n   The consistent updating of versions can be performed using:\n   ```shell script\n   % DRY_RUN=false TARGET_VERSION=\"v3.5.10\" ./scripts/release_mod.sh update_versions\n   ```\n2. The released modules should be tagged according to https://golang.org/ref/mod#vcs-version rules,\n   i.e. each module should get its own tag.\n   The tagging can be performed using:\n   ```shell script\n   % DRY_RUN=false REMOTE_REPO=\"origin\" ./scripts/release_mod.sh push_mod_tags\n   ```\n\n3. All etcd modules should depend on the same versions of underlying dependencies.\n   This can be verified using:\n   ```shell script\n   % PASSES=\"dep\" ./test.sh\n   ```\n\n4.

    "content": "# Analyzing Prow Job Resource Usage\n\n## 1. Introduction to Prow\n\n[Prow](https://docs.prow.k8s.io/docs/) is a Kubernetes based CI/CD system. Jobs can be triggered by various types of events and report their status to many different services. Prow provides GitHub automation through policy enforcement and chat-ops via `/command` interactions on pull requests (e.g., `/test`, `/approve`, `/retest`), enabling contributors to trigger jobs and manage workflows directly from GitHub comments.\n\nWhen a user comments `/ok-to-test`or `/retest,` on a Pull Request, GitHub sends a webhook to Prow's Kubernetes cluster. Visit this [site](https://docs.prow.k8s.io/docs/life-of-a-prow-job/) to further understand the lifecycle of a Prow job.\nThis is where you can find all etcd Prow jobs [status](https://prow.k8s.io/?repo=etcd-io%2Fetcd)\n\n## 2. How Prow is used for etcd Testing\n\netcd's CI is managed by [kubernetes/test-infra](https://github.com/kubernetes/test-infra), running Prow.\n\nWhen a pull request is submitted, or a `/command` is issued, the CI of etcd which managed by [kubernetes/test-infra](https://github.com/kubernetes/test-infra) uses Prow to run the tests. You can view all supported Prow [commands](https://prow.k8s.io/command-help).\n\n### Jobs Types\n\nThe jobs [configuration](https://github.com/kubernetes/test-infra/tree/master/config/jobs/etcd) for etcd. Please see [ProwJob](https://docs.prow.k8s.io/docs/jobs/) docs for more info.\n\nThere are 3 different job types:\n\n- Recurring jobs that regularly run etcd performance benchmarks, specifically targeting the put API, for the amd64 architecture.[etcd-benchmarks-periodics.yaml](https://github.com/kubernetes/test-infra/blob/master/config/jobs/etcd/etcd-benchmarks-periodic.yaml)\n- Presubmits jobs: Run on pull requests before code is merged, ensuring new changes do not break the build or tests. [etcd-operator-presubmits.yaml](https://github.com/kubernetes/test-infra/blob/master/config/jobs/etcd/etcd-presubmits.yaml)\n- Postsubmits run after merging the etcd-io/etcd-operator code: [etcd-operator-postsubmits.yaml](https://github.com/kubernetes/test-infra/blob/master/config/jobs/etcd/etcd-operator-postsubmits.yaml)\n- Periodic jobs are jobs that run automatically on a fixed schedule (such as every 4 hours, once a day, etc.), regardless of code changes or pull requests. They’re designed to continuously check the stability, compatibility, or performance of the project over time. [etcd-periodics.yaml](https://github.com/kubernetes/test-infra/blob/master/config/jobs/etcd/etcd-periodics.yaml)\n- Builds the etcd project for all main and release branches before merging any PR. [etcd-presubmits.yaml](https://github.com/kubernetes/test-infra/blob/master/config/jobs/etcd/etcd-presubmits.yaml)\n- This file defines jobs that run automatically after code is merged (postsubmit) into the main or release branches of the etcd repository (etcd-io/etcd). [etcd-postsubmits.yaml](https://github.com/kubernetes/test-infra/blob/master/config/jobs/etcd/etcd-postsubmits.yaml)\n- Test pull requests for the etcd-io/raft repository on certain branches (main and release-3.6)[etcd-raft-presubmits.yaml](https://github.com/kubernetes/test-infra/blob/master/config/jobs/etcd/etcd-raft-presubmits.yaml)\n- Checks markdown formatting for website changes [etcd-website-presubmits.yaml](https://github.com/kubernetes/test-infra/blob/master/config/jobs/etcd/etcd-website-presubmits.yaml).\n- This file contains jobs that run after code is merged into the etcd-io/protodoc repository. [protodoc-presubmit.yaml](https://github.com/kubernetes/test-infra/blob/master/config/jobs/etcd/protodoc-postsubmits.yaml)\n- This file defines jobs that run on pull requests (before merge) for the etcd-io/protodoc repository.[protodoc-postsubmit.yaml](https://github.com/kubernetes/test-infra/blob/master/config/jobs/etcd/protodoc-presubmits.yaml)\n\nAs an example, `pull-etcd-e2e-amd64` is one of the [presubmits](https://github.com/kubernetes/test-infra/blob/b21a1d3a72d5715ea7c9234cade21751847cfbe5/config/jobs/etcd/etcd-presubmits.yaml#L193). The job automatically runs end-to-end (e2e) tests on the amd64 architecture for every pull request to the etcd repository targeting the main, release-3.6, release-3.5, or release-3.4 branches. This is an example to its dashboard result [graph](https://prow.k8s.io/?repo=etcd-io%2Fetcd&type=presubmit&job=pull-etcd-e2e-amd64).\n\nRefer to [the test-infra Job Types documentation](https://github.com/kubernetes/test-infra/tree/master/config/jobs#job-types) to learn more about them.\n\n### How to Trigger Prow Running Tests\n\nThese tests can be triggered when you leave a comment, like `/ok-to-test` (only triggered by an etcd-io member) or `/retest`, in PR [example](https://github.com/etcd-io/etcd/pull/20733#issuecomment-3341443205). `/ok-to-test` allows Prow to run tests on a pull request from a first-time contributor. `/retest` tells Prow to rerun any failed or flaky joobs on the pull request, useful if a previous test failed due to a transient issue.\n\nYou can find all supported [commands](https://prow.k8s.io/command-help).\n\n## 3. Navigating Performance Dashboard (Grafana)\n\nTest-infra's Prow exposes Grafana dashboards to provide visibility into build resource usage (CPU, memory, number of running builds, etc.) for the Prow build cluster’s Kubernetes jobs. It is scoped via organization, repository, build identifier and time range filters.\n\n- GKE Dashboards: [https://monitoring-gke.prow.k8s.io/d/96Q8oOOZk/builds?orgId=1&refresh=30s&var-org=etcd-io&var-repo=etcd&var-build=All&from=now-7d&to=now](https://monitoring-gke.prow.k8s.io/d/96Q8oOOZk/builds?orgId=1&refresh=30s&var-org=etcd-io&var-repo=etcd&var-build=All&from=now-7d&to=now)\n- EKS Dashboards: [https://monitoring-eks.prow.k8s.io/d/96Q8oOOZk/builds?orgId=1&refresh=30s&var-org=etcd-io&var-repo=etcd&var-build=All&from=now-7d&to=now](https://monitoring-eks.prow.k8s.io/d/96Q8oOOZk/builds?orgId=1&refresh=30s&var-org=etcd-io&var-repo=etcd&var-build=All&from=now-7d&to=now)\n\nIt is useful for a few reasons:\n\n1. Tuning resources: By drilling into each build-run, you can determine realistic memory & CPU requests and limits for that job‑type. This helps avoid waste or avoid failed builds hitting resource limits.\n\n2. Spotting anomalies: If one build suddenly used 8 GiB while normally this job uses 1 GiB, it may indicate a regression or mis‑configuration.\n\n3. Capacity planning: Seeing typical and peak usage helps cluster operators plan node sizes, scheduling, concurrency of builds, etc.\n\n4. Debugging performance issues: A build with unexpectedly high CPU or memory might be stuck, looping, or consuming resources inefficiently.\n\n### Panel: “Running / Pending Builds”\n\nShows the number of builds that are in Running vs Pending states over time.\nUse it to track build backlog or concurrency — e.g., if the “Pending” line rises, builds may be waiting for resources.\nIf the “Running” line fluctuates a lot or remains at some steady value, you can infer how many builds typically run in parallel.\n\n### Panel: “Memory Usage per Build”\n\nShows memory usage over time for each build ID (each build listed in the legend at the bottom).\nThe y‑axis shows memory use (e.g., in MiB / GiB).\nUse this to spot builds with unusually high memory usage — a spike indicates one build consumed many resources.\n\n### Panel: “CPU Usage per Build”\n\nSimilar to the memory panel but shows CPU usage per build over time. Spikes in CPU usage may indicate heavy compute jobs, inefficiencies, or need for resource tuning.\n\n### Panel: \"Resources\"\n\n- Memory panel\n\nGreen line (“used”): how much memory this build’s pod was using at each time point. Orange/Yellow line (“requested”): how much memory was requested (i.e., Kubernetes requests.memory) for that pod.\nRed line (“limit”): how much memory was limited (i.e., Kubernetes limits.memory) for that pod.\nY‑axis: shows memory (GiB, MiB) over the build runtime.\n\nX‑axis: time of day/date.\nIf the green “used” line is close to or hits the red “limit”, it means the build came close to its memory cap (risking OOM). If “used” is much lower than “requested”, you may be over‑allocating memory (waste).\nIf the “requested” line is much higher than “used”, it suggests the job’s request could be tuned downward.\n\n- CPU panel\n\nSimilar structure: green = actual usage, orange/yellow = requested CPU, red = CPU limit (if set).\nY‑axis often in number of CPU cores or fraction thereof (e.g., 1.0 = one core).\nA green line with spikes may show bursts of CPU usage (e.g., build or compile phases) while idle periods show low usage.\nIf CPU usage consistently saturates the limit, the job may be throttled or delayed. If usage is consistently far below request, tuning may reduce cost.\n\n## 3.1 Prow job categories (robustness, integration, static checks)\n\n- Static check:\n  - Description: Fast, deterministic checks (build, unit tests, linters, go vet/staticcheck, formatting, license/header checks, generated-code verification) that catch style, correctness and packaging problems early.\n  - When to run: Every PR as presubmits; quick feedback loop before running expensive tests.\n  - Example job patterns: pull-etcd-verify, pull-etcd-lint, pull-etcd-unit\n\n- Tests:\n  - Robustness:\n    - Description: Long-running, fault-injection and chaos-style end-to-end tests that validate etcd correctness and availability under failures (node crashes, network partitions, resource exhaustion, upgrades).\n    - When to run: Periodics for continuous coverage; run for PRs that touch consensus, storage, recovery, or upgrade paths.\n    - Example job patterns: pull-etcd-robustness, periodic-robustness\n\n  - Integration:\n    - Description: Functional end-to-end and cross-component tests that exercise real client/server interactions, snapshots/restore, upgrades and compatibility across OS/arch.\n    - When to run: Presubmits for PRs that change APIs, client behavior, or integration points; periodics for broad platform coverage.\n    - Example job patterns: pull-etcd-e2e-amd64, pull-etcd-integration\n\n## 4. Interpreting Metrics\n\nSome Prow components expose Prometheus metrics that can be used for monitoring and alerting. You can find metrics like the number of PRs in each Tide pool, a histogram of the number of PRs in each merge and various other metrics to this [site](https://github.com/kubernetes-sigs/prow/blob/main/site/content/en/docs/metrics/_index.md).\n"

    "path": "Documentation/contributor-guide/release.md",
    "content": "# Release\n\nThe guide talks about how to release a new version of etcd.\n\nThe procedure includes some manual steps for sanity checking, but it can probably be further scripted. Please keep this document up-to-date if making changes to the release process.\n\n## Release management\n\nUnder the leadership of **James Blair** [@jmhbnz](https://github.com/jmhbnz) and **Ivan Valdes Castillo** [@ivanvc](https://github.com/ivanvc), the following pool of release candidates manages the release of each etcd major/minor version as well as manages patches\nto each stable release branch. They are responsible for communicating the timelines and status of each release and\nfor ensuring the stability of the release branch.\n\n- Benjamin Wang [@ahrtr](https://github.com/ahrtr)\n- Fu Wei [@fuweid](https://github.com/fuweid)\n- James Blair [@jmhbnz](https://github.com/jmhbnz)\n- Ivan Valdes Castillo [@ivanvc](https://github.com/ivanvc)\n- Marek Siarkowicz [@serathius](https://github.com/serathius)\n- Sahdev Zala [@spzala](https://github.com/spzala)\n- Siyuan Zhang [@siyuanfoundation](https://github.com/siyuanfoundation)\n\nAll release version numbers follow the format of [semantic versioning 2.0.0](http://semver.org/).\n\n### Major, minor version release, or its pre-release\n\n- Ensure the relevant [milestone](https://github.com/etcd-io/etcd/milestones) on GitHub is complete. All referenced issues should be closed or moved elsewhere.\n- Ensure the latest [upgrade documentation](https://etcd.io/docs/next/upgrades) is available.\n- Bump [hardcoded MinClusterVerion in the repository](https://github.com/etcd-io/etcd/blob/v3.4.15/version/version.go#L29), if necessary.\n- Add feature capability maps for the new version, if necessary.\n\n### Patch version release\n\n- To request a backport, developers submit cherry-pick PRs targeting the release branch. The commits should not include merge commits. The commits should be restricted to bug fixes and security patches.\n- The cherrypick PRs should target the appropriate release branch (`base:release-<major>-<minor>`). The k8s infra cherry pick robot `/cherrypick <branch>` PR chatops command may be used to automatically generate cherrypick PRs.\n- The release patch manager reviews the cherrypick PRs. Please discuss carefully what is backported to the patch release. Each patch release should be strictly better than its predecessor.\n- The release patch manager will cherry-pick these commits starting from the oldest one into stable branch.\n\n## Write a release note\n\n- Write an introduction for the new release. For example, what major bug we fix, what new features we introduce, or what performance improvement we make.\n- Put `[GH XXXX]` at the head of the change line to reference the Pull Request that introduces the change. Moreover, add a link on it to jump to the Pull Request.\n- Find PRs with the `release-note` label and explain them in the `NEWS` file, as a straightforward summary of changes for end-users.\n\n## Patch release criteria\n\nThe etcd project aims to release a new patch version if any of the following conditions are met:\n\n- Fixed one or more major CVEs (>=7.5).\n- Fixed one or more critical bugs.\n- Fixed three or more major bugs.\n- Fixed five or more minor bugs.\n\n## Release guide\n\n### Prerequisites\n\nThere are some prerequisites, which should be done before the release process. These are one-time operations,\nwhich don't need to be executed before releasing each version.\n1. Generate a GPG key and add it to your GitHub account. Refer to the links on [settings](https://github.com/settings/keys).\n2. Ensure you have a Linux machine, on which the git, Golang, and docker have been installed.\n    - Ensure the Golang version matches the version defined in `.go-version` file.\n    - Ensure non-privileged users can run docker commands, refer to the [Linux postinstall](https://docs.docker.com/engine/install/linux-postinstall/).\n    - Ensure there is at least 5GB of free space on your Linux machine.\n3. Install gsutil, refer to [gsutil_install](https://cloud.google.com/storage/docs/gsutil_install). When asked about cloud project to use, pick `etcd-development`.\n4. Authenticate the image registry, refer to [Authentication methods](https://cloud.google.com/container-registry/docs/advanced-authentication).\n   - `gcloud auth login`\n   - `gcloud auth configure-docker`\n5. Install gh, refer to [GitHub's documentation](https://github.com/cli/cli#installation). Ensure that running\n   `gh auth login` succeeds for the GitHub account you use to contribute to etcd,\n   and that `gh auth status` has a clean exit and doesn't show any issues.\n\n### Release steps\n\nAt least one day before the release:\n\n1. Raise an issue to publish the release plan, e.g. [issues/17350](https://github.com/etcd-io/etcd/issues/17350).\n2. Raise a `kubernetes/org` pull request ([example PR](https://github.com/kubernetes/org/pull/5582)) to ensure members of the release team are added to the [release github team](https://github.com/orgs/etcd-io/teams/release-etcd).\n\nOn the day of the release:\n\n1. Verify you can pass the authentication to the image registries,\n   - `docker login gcr.io`\n   - `docker login quay.io`\n     - If the release person doesn't have access to 1password, one of the owners (@ahrtr, @ivanvc, @jmhbnz, @serathius) needs to share the password with them per [this guide](https://support.1password.com/share-items/). See rough steps below,\n       - [Sign in](https://team-etcd.1password.com/home) to your account on 1password.com.\n       - Click `Your Vault Items` on the right side.\n       - Select `Password of quay.io`.\n       - Click `Share` on the top right, and set expiration as `1 hour` and only available to the release person using his/her email.\n       - Click `Copy Link` then send the link to the release person via slack or email.\n2. Clone the etcd repository and checkout the target branch,\n   - `git clone --branch release-3.X git@github.com:etcd-io/etcd.git`\n3. Run the release script under the repository's root directory, replacing `${VERSION}` with a value without the `v` prefix, i.e. `3.5.13`.\n   - `DRY_RUN=false ./scripts/release.sh ${VERSION}`\n   - **NOTE:** When doing a pre-release (i.e., a version from the main branch, 3.6.0-alpha.2), you will need to explicitly set the branch to main:\n\n     ```bash\n     DRY_RUN=false BRANCH=main ./scripts/release.sh ${VERSION}\n     ```\n\n   It generates all release binaries under the directory `/tmp/etcd-release-${VERSION}/etcd/release/` and images. Binaries are pushed to the Google Cloud bucket\n   under project `etcd-development`, and images are pushed to `quay.io` and `gcr.io`.\n   - It is advisable to do a dry run before the actual release. This will create a `/tmp` directory. Do **NOT** forget to remove this directory before the actual release.\n\n      ```bash\n      DRY_RUN=true BRANCH=${BRANCH} ./scripts/release.sh ${VERSION}\n      ```\n\n4. Publish the release page on GitHub\n   - Open the **draft** release URL shown by the release script\n   - Click the pen button at the top right to edit the release\n   - Review that it looks correct, reviewing that the bottom checkboxes are checked depending on the\n     release version (v3.4 & v3.5 no checkboxes, v3.6 has the set as latest release checkbox checked,\n     v3.7 has the set as pre-release checkbox checked)\n   - Then, publish the release\n5. Announce to the etcd-dev googlegroup\n\n   Follow the format of previous release emails sent to etcd-dev@googlegroups.com, see an example below. After sending out the email, ask one of the mailing list maintainers to approve the email from the pending list. Additionally, label the release email as `Release`.\n\n   ```text\n   Hello,\n\n   etcd v3.4.30 is now public!\n\n   https://github.com/etcd-io/etcd/releases/tag/v3.4.30\n\n   Thanks to everyone who contributed to the release!\n\n   etcd team\n   ```\n\n6. Update the changelog to reflect the correct release date.\n7. Paste the release link to the issue raised in Step 1 and close the issue.\n8. Raise a follow-up `kubernetes/org` pull request to return the GitHub release team to empty, least privilege state.\n9. Crease a new stable branch through `git push origin release-${VERSION_MAJOR}.${VERSION_MINOR}` if this is a new major or minor stable release.\n10. Re-generate a new password for quay.io if needed (e.g. shared to a contributor who isn't in the release team, and we should rotate the password at least once every 3 months).\n11. Bump the new etcd release in Kubernetes, refer to [Bump etcd Version in Kubernetes](bump_etcd_version_k8s.md).\n\n- For etcd 3.6 patches, bump it to Kubernetes 1.34 and all newer minor versions (including `master` branch)\n- For etcd 3.5 patches, bump it to Kubernetes 1.33 and all older supported versions\n\n#### Release known issues\n\n1. Timeouts pushing binaries - If binaries fail to fully upload to Google Cloud storage, the script must be re-run using the same command. Any artifacts that are already pushed will be overwritten to ensure they are correct. The storage bucket does not use object versioning so incorrect files cannot remain.\n\n2. Timeouts pushing images - It is rare, although possible for connection timeouts to occur when publishing etcd release images to `quay.io` or `gcr.io`. If this occurs, it is known to be safe to rerun the release script command appending the `--no-upload` flag, and image uploads will gracefully resume.\n\n3. GPG vs SSH signing - The release scripts assume that git tags will be signed with a GPG key. Since 2022 GitHub has supported [signing commits and tags using ssh](https://github.blog/changelog/2022-08-23-ssh-commit-verification-now-supported). Until further release script updates are completed you will need to disable this feature in your `~/.gitconfig` and revert to signing via GPG to perform etcd releases.\n"

    "content": "# Issue triage guidelines\n\n## Purpose\n\nSpeed up issue management.\n\nThe `etcd` issues are listed at <https://github.com/etcd-io/etcd/issues> and are identified with labels. For example, an issue that is identified as a bug will be set to the label `type/bug`.\n\nThe etcd project uses labels to indicate common attributes such as `area`, `type`, and `priority` of incoming issues.\n\nNew issues will often start without any labels, but typically `etcd` maintainers, reviewers, and members will add labels by following these triage guidelines. The detailed list of labels can be found at <https://github.com/etcd-io/etcd/labels>.\n\n## Scope\n\nThis document serves as the primary guidelines for triaging incoming issues in `etcd`.\n\nAll contributors are encouraged and welcome to help manage issues which will help reduce the burden on project maintainers, though the work and responsibilities discussed in this document are created with `etcd` project reviewers and members in mind as these individuals will have triage access to the etcd project which is a requirement for actions like applying labels or closing issues.\n\nRefer to [etcd community membership](https://github.com/etcd-io/etcd/blob/main/Documentation/contributor-guide/community-membership.md) for guidance on becoming an etcd project member or reviewer.\n\n## Step 1 - Find an issue to triage\n\nTo get started you can use the following recommended issue searches to identify issues that are in need of triage:\n\n* [Issues that have no labels](https://github.com/etcd-io/etcd/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated+no%3Alabel)\n* [Issues created recently](https://github.com/etcd-io/etcd/issues?q=is%3Aissue+is%3Aopen+)\n* [Issues not assigned but linked pr](https://github.com/etcd-io/etcd/issues?q=is%3Aopen+is%3Aissue+no%3Aassignee+linked%3Apr)\n* [Issues with no comments](https://github.com/etcd-io/etcd/issues?q=is%3Aopen+is%3Aissue+comments%3A0+)\n* [Issues with help wanted](https://github.com/etcd-io/etcd/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22+)\n\n## Step 2 - Check the issue is valid\n\nBefore we start adding labels or trying to work out a priority, our first triage step needs to be working out if the issue actually belongs to the etcd project and is not a duplicate.\n\n### Issues that don't belong to etcd\n\nSometimes issues are reported that belong to other projects that `etcd` use. For example, `grpc` or `golang` issues. Such issues should be addressed by asking the reporter to open issues in the appropriate other projects.\n\nThese issues can generally be closed unless a maintainer and issue reporter see a need to keep it open for tracking purposes. If you have triage permissions please close it, alternatively mention the @etcd-io/members group to request a member with triage access to close the issue.\n\n### Duplicate issues\n\nIf an issue is a duplicate, add a comment stating so along with a reference for the original issue and if you have triage permissions please close it, alternatively mention the @etcd-io/members group to request a member with triage access close the issue.\n\n## Step 3 - Apply the appropriate type of label\n\nAdding a `type` label to an issue helps create visibility on the health of the project and helps contributors identify potential priorities, i.e. addressing existing bugs or test flakes before implementing new features.\n\n### Support requests\n\nAs a general rule, the focus for etcd support is to address common themes in a broad way that helps all users, i.e. through channels like known issues, frequently asked questions, and high-quality documentation. To make the best use of project members time we should avoid providing 1:1 support if a broad approach is available.\n\nSome people mistakenly use our GitHub bug report or feature request templates to file support requests. Usually, they are asking for help operating or configuring some aspect of etcd. Support requests for etcd should instead be raised as [discussions](https://github.com/etcd-io/etcd/discussions).\n\nCommon types of support requests are:\n\n 1. Questions about configuring or operating existing well-documented etcd features, for example, <https://github.com/etcd-io/etcd/issues/15945>. Note - If an existing feature is not well documented please apply the `area/documentation` label and propose documentation improvements that would prevent future users from stumbling on the problem again.\n\n 2. Bug reports or questions about unsupported versions of etcd, for example <https://github.com/etcd-io/etcd/issues/15796>. When responding to these issues please refer to our [supported versions documentation](https://etcd.io/docs/latest/op-guide/versioning) and encourage the reporter to upgrade to a recent patch release of a supported version as soon as possible. We should limit the effort supporting users that do not make the effort to run a supported version of etcd or ensure their version is patched.\n\n 3. Bug reports that do not provide a complete list of steps to reproduce the issue and/or contributors are not able to reproduce the issue, for example, <https://github.com/etcd-io/etcd/issues/15740>. We should limit the effort we put into reproducing issues ourselves and motivate users to provide the necessary information to accept the bug report.\n\n 4. General questions that are filed using feature request or bug report issue templates, for example, <https://github.com/etcd-io/etcd/issues/15914>. Note - These types of requests may surface good additions to our [frequently asked questions](https://etcd.io/docs/v3.5/faq).\n\nIf you identify that an issue is a support request please:\n\n 1. Add the `type/support` or `type/question` label.\n\n 2. Add the following comment to inform the issue creator that discussions should be used instead and that this issue will be converted to a discussion.\n\n    > Thank you for your question, this support issue will be moved to our [Discussion Forums](https://github.com/etcd-io/etcd/discussions).\n    >\n    > We are trying to consolidate the channels to which questions for help/support are posted so that we can improve our efficiency in responding to your requests, and make it easier for you to find answers to frequently asked questions and how to address common use cases.\n    >\n    > We regularly see messages posted in multiple forums, with the full response thread only in one place or, worse, spread across multiple forums. Also, the large volume of support issues on GitHub is making it difficult for us to use issues to identify real bugs.\n    >\n    > Members of the etcd community use Discussion Forums to field support requests. Before posting a new question, please search these for answers to similar questions, and also familiarize yourself with:\n    >\n    > 1. [user documentation](https://etcd.io/docs/latest)\n    > 2. [frequently asked questions](https://etcd.io/docs/v3.5/faq)\n    >  \n    > Again, thanks for using etcd and raising this question.\n    >\n    > The etcd team\n\n 3. Finally, click `Convert to discussion` on the right-hand panel, selecting the appropriate discussion category.\n\n### Bug reports\n\nIf an issue has been raised as a bug it should already have the `type/bug` label, however, if this is missing for an issue you determine to be a bug please add the label manually.\n\nThe next step is to validate if the issue is indeed a bug. If not, add a comment with the findings and close the trivial issue. For non-trivial issues, wait to hear back from the issue reporter and see if there is any objection. If the issue reporter does not reply in 30 days, close the issue.\n\nIf the problem can not be reproduced or requires more information, leave a comment for the issue reporter as soon as possible while the issue is fresh for the issue reporter.\n\n### Feature requests\n\nNew feature requests should be created via the etcd feature request template and in theory already have the `type/feature` label, however, if this is missing for an issue you determine to be a feature please add the label manually.\n\n### Test flakes\n\nTest flakes are a specific type of bug that the etcd project tracks separately as these are a priority to address. These should be created via the test flake template and in theory already have the `type/flake` label, however, if this is missing for an issue you determine to be related to a flaking test please add the label manually.\n\n## Step 4 - Define the areas impacted\n\nAdding an `area` label to an issue helps create visibility on which areas of the etcd project require attention and helps contributors find issues to work on relating to their particular skills or knowledge of the etcd codebase.\n\nIf an issue crosses multiple domains please add additional `area` labels to reflect that.\n\nBelow is a brief summary of the area labels in active use by the etcd project along with any notes on their use:\n\n| Label                   | Notes                                                         |\n| ---                     | ---                                                           |\n| area/external           | Tracking label for issues raised that are external to etcd.   |\n| area/community          |                                                               |\n| area/raft               |                                                               |\n| area/clientv3           |                                                               |\n| area/performance        |                                                               |\n| area/security           |                                                               |\n| area/tls                |                                                               |\n| area/auth               |                                                               |\n| area/etcdctl            |                                                               |\n| area/etcdutl            |                                                               |\n| area/contrib            | Not to be confused with `area/community` this label is specifically used for issues relating to community-maintained scripts or files in the `contrib/` directory which aren't part of the core etcd project. |\n| area/documentation      |                                                               |\n| area/tooling            | Generally used in relation to the third party / external utilities or tools that are used in various stages of the etcd build, test, or release process, for example, tooling to create sboms.          |\n| area/testing            |                                                               |\n| area/robustness-testing |                                                               |\n\n## Step 5 - Prioritise the issue\n\nIf an issue lacks a priority label it has not been formally prioritized yet.\n\nAdding a `priority` label helps the etcd project understand what is important and should be worked on now, and conversely, what is not as important and is on the project backlog.\n\n|Priority label|What it means|Examples|\n|---|---|---|\n| `priority/critical-urgent` | Maintainers are responsible for making sure that these issues (in their area) are being actively worked on—i.e., drop what you're doing. The stuff is burning. These should be fixed before the next release. | user-visible critical bugs in core features <br> broken builds on tier1 supported platforms <br> tests and critical security issues |\n| `priority/important-soon` | Must be staffed and worked on either currently or very soon—ideally in time for the next release. | |\n| `priority/important-longterm` | Important over the long term, but may not be currently staffed and/or may require multiple releases to complete. | |\n| `priority/backlog`  | General agreement that this is a nice-to-have, but no one's available to work on it anytime soon. Community contributions would be most welcome in the meantime, though it might take a while to get them reviewed if reviewers are fully occupied with higher-priority issues—for example, immediately before a release.| |\n| `priority/awaiting-more-evidence` | Possibly useful, but not yet enough support to actually get it done. | Mostly placeholders for potentially good ideas, so that they don't get completely forgotten, and can be referenced or deduped every time they come up |\n\n## Step 6 - Support new contributors\n\nAs part of the `etcd` triage process once the `kind` and `area` have been determined, please consider if the issue would be suitable for a less experienced contributor. The `good first issue` label is a subset of the `help wanted` label, indicating that members have committed to providing extra assistance for new contributors. All `good first issue` items also have the `help wanted` label.\n\n### Help wanted\n\nItems marked with the `help wanted` label need to ensure that they meet these criteria:\n\n* **Low Barrier to Entry** - It should be easy for new contributors.\n\n* **Clear** - The task is agreed upon and does not require further discussions in the community.\n\n* **Goldilocks priority** - The priority should not be so high that a core contributor should do it, but not too low that it isn’t useful enough for a core contributor to spend time reviewing it, answering questions, helping get it into a release, etc.\n\n### Good first issue\n\nItems marked with `good first issue` are intended for first-time contributors. It indicates that members will keep an eye out for these pull requests and shepherd it through our processes.\n\nNew contributors should not be left to find an approver, ping for reviews, decipher test commands, or identify that their build failed due to a flake. It is important to make new contributors feel welcome and valued. We should assure them that they will have an extra level of help with their first contribution.\n\nAfter a contributor has successfully completed one or two `good first issue` items, they should be ready to move on to `help wanted` items.\n\n* **No Barrier to Entry** - The task is something that a new contributor can tackle without advanced setup or domain knowledge.\n\n* **Solution Explained** - The recommended solution is clearly described in the issue.\n\n* **Gives Examples** - Link to examples of similar implementations so new contributors have a reference guide for their changes.\n\n* **Identifies Relevant Code** - The relevant code and tests to be changed should be linked in the issue.\n\n* **Ready to Test** - There should be existing tests that can be modified, or existing test cases fit to be copied. If the area of code doesn’t have tests, before labeling the issue, add a test fixture. This prep often makes a great help wanted task!\n\n## Step 7 - Follow up\n\nOnce initial triage has been completed, issues need to be re-evaluated over time to ensure they don't become stale incorrectly.\n\n### Track important issues\n\nIf an issue is at risk of being closed by the stale bot in the future, but is an important issue for the etcd project, then please apply the `stage/tracked` label and remove any `stale` labels that exist. This will ensure the project does not lose sight of the issue.\n\n### Close incomplete issues\n\nIssues that lack enough information from the issue reporter should be closed if the issue reporter does not provide information in 30 days. Issues can always be re-opened at a later date if new information is provided.\n\n### Check for incomplete work\n\nIf an issue owned by a developer has no pull request created in 30 days, contact the issue owner and kindly ask about the status of their work, or to release ownership on the issue if needed.\n"

    "content": "# PR management\n\n## Purpose\n\nSpeed up PR management.\n\nThe `etcd` PRs are listed at https://github.com/etcd-io/etcd/pulls\nA PR can have various labels, milestones, reviewers, etc. The detailed list of labels can be found at\nhttps://github.com/kubernetes/kubernetes/labels\n\nFollowing are a few example searches on PR for convenience:\n* [Open PRS for milestone etcd-v3.6](https://github.com/etcd-io/etcd/pulls?utf8=%E2%9C%93&q=is%3Apr+is%3Aopen+milestone%3Aetcd-v3.6)\n* [PRs under investigation](https://github.com/etcd-io/etcd/labels/Investigating)\n\n## Scope\n\nThese guidelines serve as a primary document for managing PRs and review policy in `etcd`. Everyone is welcome to help manage PRs but the work and responsibilities discussed in this document are created with `etcd` maintainers and active contributors in mind.\n\n## Ensure tests are run\n\nThe etcd project use Kubernetes Prow and GitHub Actions to run tests. To ensure all required tests run if a pull request is ready for testing and still has the `needs-ok-to-test` label then please comment on the pull request `/ok-to-test`.\n\n## Handle inactive PRs\nPoke PR owner if review comments are not addressed in 15 days. If the PR owner does not reply in 90 days, update the PR with a new commit if possible. If not, inactive PR should be closed after 180 days.\n\n## Poke reviewer if needed\n\nReviewers are responsive in a timely fashion, but considering everyone is busy, give them some time after requesting a review if a quick response is not provided. If the response is not provided in 10 days, feel free to contact them via adding a comment in the PR or sending an email or message on Slack.\n\n## Verify important labels are in place\n\nMake sure that appropriate reviewers are added to the PR. Also, make sure that a milestone is identified. If any of these or other important labels are missing, add them. If a correct label cannot be decided, leave a comment for the maintainers to do so as needed.\n\n## Review policy\n\nTo ensure code quality and shared ownership, this review policy applies to all pull requests (PRs).\n\n### Default rule\n\nPRs should get at least two approvals (/lgtm or GitHub review approval) before merging.\n\nNotes:\n\n* Approvals should come from a maintainer, reviewer, or submodule owner familiar with the relevant code or area.\n* If there’s disagreement, maintainers should discuss and agree before merging.\n\n### Exceptions for Less Impactful PRs\n\nFor low-risk changes — such as:\n\n* CI workflows\n* Documentation\n* Comments\n\nThe rule can be relaxed:\n\n* One approval is generally enough.\n\nHowever:\n\n* If the author is a maintainer, they should still get approval from another maintainer, reviewer, or submodule owner, even for minor changes.\n"

Independent crash could lead to committed transactions are not reflected on all the members.                                                 |\n| Impact  | No user reported problems in production as triggering the issue required frequent crashes, however issue was critical enough to motivate a public statement. Main impact comes from loosing user trust into etcd reliability. |\n\n## Background\n\netcd v3 state is preserved on disk in two forms write ahead log (WAL) and database state (DB).\netcd v3.5 also still maintains v2 state, however it's deprecated and not relevant to the issue in this postmortem.\n\nWAL stores history of changes for etcd state and database represents state at one point. \nTo know which point of history database is representing, it stores consistent index (CI).\nIt's a special metadata field that points to last entry in WAL that it has seen.\n\nWhen etcd is updating database state, it replays entries from WAL and updates the consistent index to point to new entry.\nThis operation is required to be [atomic](https://en.wikipedia.org/wiki/Atomic_commit). \nA partial fail would mean that database and WAL would no longer match, so some entries would be either skipped (if only CI is updated) or executed twice (if only changes are applied).\nThis is especially important for distributed system like etcd, where there are multiple cluster members, each applying the WAL entries to their database.\nCorrectness of the system depends on assumption that every member of the cluster, while replying WAL entries, will reach the same state.\n\n## Root cause\n\nTo simplify managing consistency index, etcd has introduced backend hooks in https://github.com/etcd-io/etcd/pull/12855.\nGoal was to ensure that consistency index is always updated, by automatically triggering update during commit.\nImplementation was as follows, before applying the WAL entries, etcd updated in memory value of consistent index. \nAs part of transaction commit process, a database hook would read the value of consistent index and store it to database. \n\nProblem is that in memory value of consistent index is shared, and there might be other in flight transactions apart from serial WAL apply flow.\nSo if we imagine scenario:\n1. etcd server starts an apply workflow, and it just sets a new consistent index value.\n2. The periodic commit is triggered, and it executes the backend hook and saves consistent index from apply workflow.\n3. etcd server finished an apply workflow, saves new changes and saves same value of consistent index again.\n\nBetween second and third point there is a very small window where consistent index is increased without applying entry from WAL.\n\n## Trigger\n\nIf etcd crashed after consistency index is saved, but before to apply workflow finished it would lead to data inconsistency.\nWhen recovering the data etcd would skip executing changes from failed apply workflow, assuming they have been already executed.\n\nThis follows the issue reports and code used to reproduce the issue where trigger was etcd crashing under high request load.\nEtcd v3.5.0 was released with bug (https://github.com/etcd-io/etcd/pull/13505) that could cause etcd to crash that was fixed in v3.5.1.\nApart from that all reports described etcd running under high memory pressure, causing it to go out of memory from time to time.\nReproduction run etcd under high stress and randomly killed one of the members using SIGKILL signal (not recoverable immediate process death). \n\n## Detection\n\nFor single member cluster it is totally undetectable. \nThere is no mechanism or tool for verifying that state database matches WAL.  \n\nIn cluster with multiple members it would mean that one of the members that crashed, will missing changes from failed apply workflow.\nThis means that it will have different state of database and will return different hash via `HashKV` grpc call.\n\nThere is an automatic mechanism to detect data inconsistency. \nIt can be executed during etcd start via `--experimental-initial-corrupt-check` and periodically via `--experimental-corrupt-check-time`.\nBoth checks however have a flaw, they depend on `HashKV` grpc method, which might fail causing the check to pass.\n\nIn multi member etcd cluster, each member can run with different performance and be at different stage of applying the WAL log.\nComparing database hashes between multiple etcd members requires all hashes to be calculated at the same change.\nThis is done by requesting hash for the same `revision` (version of key value store). \nHowever, it will not work if the provided revision is not available on the members.\nThis can happen on very slow members, or in cases where corruption has lead revision numbers to diverge.\n\nThis means that for this issue, the corrupt check is only reliable during etcd start just after etcd crashes.\n\n## Impact\n\nWe are not aware any cases of users reporting a data corruption in production environment.\n\nHowever, issue was critical enough to motivate a public statement. \nMain impact comes from loosing user trust into etcd reliability.\n\n## Lessons learned\n\n### What went well\n\n* Multiple maintainers were able to work effectively on reproducing and fixing the issue. As they are in different timezones, there was always someone working on the issue.\n* When fixing the main data inconsistency we have found multiple other edge cases that could lead to data corruption (https://github.com/etcd-io/etcd/issues/13514, https://github.com/etcd-io/etcd/issues/13922, https://github.com/etcd-io/etcd/issues/13937).\n\n### What went wrong\n\n* No users enable data corruption detection as it is still an experimental feature introduced in v3.3. All reported cases where detected manually making it almost impossible to reproduce.\n* etcd has functional tests designed to detect such problems, however they are unmaintained, flaky and are missing crucial scenarios.\n* etcd v3.5 release was not qualified as comprehensive as previous ones. Older maintainers run manual qualification process that is no longer known or executed.\n* etcd apply code is so complicated that fixing the data inconsistency took almost 2 weeks and multiple tries. Fix needed to be so complicated that we needed to develop automatic validation for it (https://github.com/etcd-io/etcd/pull/13885).\n* etcd v3.5 was recommended for production without enough insight on the production adoption. Production ready recommendations based on after some internal feedback... to get diverse usage, but the user's hold on till someone else will discover issues.\n\n### Where we got lucky\n\n* We reproduced the issue using etcd functional only because weird partition setup on workstation. Functional tests store etcd data under `/tmp` usually mounted to in memory filesystem. Problem was reproduced only because one of the maintainers has `/tmp` mounted to standard disk.\n\n## Action items\n\nAction items should directly address items listed in lessons learned. \nWe should double down on things that went well, fix things that went wrong, and stop depending on luck.\n\nAction fall under three types, and we should have at least one item per type. Types:\n* Prevent - Prevent similar issues from occurring. In this case, what testing we should introduce to find data inconsistency issues before release, preventing publishing broken release.\n* Detect - Be more effective in detecting when similar issues occur. In this case, improve mechanism to detect data inconsistency issue so users will be automatically informed.\n* Mitigate - Reduce time to recovery for users. In this case, how we ensure that users are able to quickly fix data inconsistency.\n\nActions should not be restricted to fixing the immediate issues and also propose long term strategic improvements.\nTo reflect this action items should have assigned priority: \n* P0 - Critical for reliability of the v3.5 release. Should be prioritized this over all other work and backported to v3.5.\n* P1 - Important for long term success of the project. Blocks v3.6 release.\n* P2 - Stretch  goals that would be nice to have for v3.6, however should not be blocking.\n\n| Action Item                                                                         | Type     | Priority | Bug                                          | Status |\n|-------------------------------------------------------------------------------------|----------|----------|----------------------------------------------|--------|\n| etcd testing can reproduce historical data inconsistency issues                     | Prevent  | P0       | https://github.com/etcd-io/etcd/issues/14045 | DONE   |\n| etcd detects data corruption by default                                             | Detect   | P0       | https://github.com/etcd-io/etcd/issues/14039 | DONE   |\n| etcd testing is high quality, easy to maintain and expand                           | Prevent  | P1       | https://github.com/etcd-io/etcd/issues/13637 |        |\n| etcd apply code should be easy to understand and validate correctness               | Prevent  | P1       |                                              |        |\n| Critical etcd features are not abandoned when contributors move on                  | Prevent  | P1       | https://github.com/etcd-io/etcd/issues/13775 | DONE   |\n| etcd is continuously qualified with failure injection                               | Prevent  | P1       | https://github.com/etcd-io/etcd/pull/14911   | DONE   |\n| etcd can reliably detect data corruption (hash is linearizable)                     | Detect   | P1       |                                              |        |\n| etcd checks consistency of snapshots sent between leader and followers              | Detect   | P1       | https://github.com/etcd-io/etcd/issues/13973 | DONE   |\n| etcd recovery from data inconsistency procedures are documented and tested          | Mitigate | P1       |                                              |        |\n| etcd can imminently detect and recover from data corruption (implement Merkle root) | Mitigate | P2       | https://github.com/etcd-io/etcd/issues/13839 |        |\n\n## Timeline\n\n| Date       | Event                                                                                                                 |\n|------------|-----------------------------------------------------------------------------------------------------------------------|\n| 2021-05-08 | Pull request that caused data corruption was merged - https://github.com/etcd-io/etcd/pull/12855                      |\n| 2021-06-16 | Release v3.5.0 with data corruption was published - https://github.com/etcd-io/etcd/releases/tag/v3.5.0               |\n| 2021-12-01 | Report of data corruption - https://github.com/etcd-io/etcd/issues/13514                                              |\n| 2021-01-28 | Report of data corruption - https://github.com/etcd-io/etcd/issues/13654                                              |\n| 2022-03-08 | Report of data corruption - https://github.com/etcd-io/etcd/issues/13766                                              |\n| 2022-03-25 | Corruption confirmed by one of the maintainers - https://github.com/etcd-io/etcd/issues/13766#issuecomment-1078897588 |\n| 2022-03-29 | Statement about the corruption was sent to etcd-dev@googlegroups.com and dev@kubernetes.io                            |\n| 2022-04-24 | Release v3.5.3 with fix was published - https://github.com/etcd-io/etcd/releases/tag/v3.5.3                           |\n"

Reliability is further ensured by rigorous [**robustness testing**](https://github.com/etcd-io/etcd/tree/main/tests/robustness).\n\nSee [etcdctl][etcdctl] for a simple command line client.\n\n![etcd reliability is important](logos/etcd-xkcd-2347.png)\n\n<sub>Original image credited to  xkcd.com/2347, alterations by Josh Berkus.</sub>\n\n[raft]: https://raft.github.io/\n[k8s]: http://kubernetes.io/\n[doorman]: https://github.com/youtube/doorman\n[locksmith]: https://github.com/coreos/locksmith\n[vulcand]: https://github.com/vulcand/vulcand\n[etcdctl]: https://github.com/etcd-io/etcd/tree/main/etcdctl\n\n## Documentation\n\nThe most common API documentation you'll need can be found here:\n\n* [go.etcd.io/etcd/api/v3](https://godocs.io/go.etcd.io/etcd/api/v3)\n* [go.etcd.io/etcd/client/pkg/v3](https://godocs.io/go.etcd.io/etcd/client/pkg/v3)\n* [go.etcd.io/etcd/client/v3](https://godocs.io/go.etcd.io/etcd/client/v3)\n* [go.etcd.io/etcd/etcdctl/v3](https://godocs.io/go.etcd.io/etcd/etcdctl/v3)\n* [go.etcd.io/etcd/pkg/v3](https://godocs.io/go.etcd.io/etcd/pkg/v3)\n* [go.etcd.io/etcd/raft/v3](https://godocs.io/go.etcd.io/etcd/raft/v3)\n* [go.etcd.io/etcd/server/v3](https://godocs.io/go.etcd.io/etcd/server/v3)\n\n## Maintainers\n\n[Maintainers](OWNERS) strive to shape an inclusive open source project culture where users are heard and contributors feel respected and empowered. Maintainers aim to build productive relationships across different companies and disciplines. Read more about [Maintainers role and responsibilities](Documentation/contributor-guide/community-membership.md#maintainers).\n\n## Getting started\n\n### Getting etcd\n\nThe easiest way to get etcd is to use one of the pre-built release binaries which are available for OSX, Linux, Windows, and Docker on the [release page][github-release].\n\nFor more installation guides, please check out [play.etcd.io](http://play.etcd.io) and [operating etcd](https://etcd.io/docs/latest/op-guide).\n\n[github-release]: https://github.com/etcd-io/etcd/releases\n\n### Running etcd\n\nFirst start a single-member cluster of etcd.\n\nIf etcd is installed using the [pre-built release binaries][github-release], run it from the installation location as below:\n\n```bash\n/tmp/etcd-download-test/etcd\n```\n\nThe etcd command can be simply run as such if it is moved to the system path as below:\n\n```bash\nmv /tmp/etcd-download-test/etcd /usr/local/bin/\netcd\n```\n\nThis will bring up etcd listening on port 2379 for client communication and on port 2380 for server-to-server communication.\n\nNext, let's set a single key, and then retrieve it:\n\n```bash\netcdctl put mykey \"this is awesome\"\netcdctl get mykey\n```\n\netcd is now running and serving client requests. For more, please check out:\n\n* [Interactive etcd playground](http://play.etcd.io)\n* [Animated quick demo](https://etcd.io/docs/latest/demo)\n\n### etcd TCP ports\n\nThe [official etcd ports][iana-ports] are 2379 for client requests, and 2380 for peer communication.\n\n[iana-ports]: http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.txt\n\n### Running a local etcd cluster\n\nFirst install [goreman](https://github.com/mattn/goreman), which manages Procfile-based applications.\n\nOur [Procfile script](./Procfile) will set up a local example cluster. Start it with:\n\n```bash\ngoreman start\n```\n\nThis will bring up 3 etcd members `infra1`, `infra2` and `infra3` and optionally etcd `grpc-proxy`, which runs locally and composes a cluster.\n\nEvery cluster member and proxy accepts key value reads and key value writes.\n\nFollow the comments in [Procfile script](./Procfile) to add a learner node to the cluster.\n\n### Install etcd client v3\n\n```bash\ngo get go.etcd.io/etcd/client/v3\n```\n\n### Next steps\n\nNow it's time to dig into the full etcd API and other guides.\n\n* Read the full [documentation].\n* Review etcd [frequently asked questions].\n* Explore the full gRPC [API].\n* Set up a [multi-machine cluster][clustering].\n* Learn the [config format, env variables and flags][configuration].\n* Find [language bindings and tools][integrations].\n* Use TLS to [secure an etcd cluster][security].\n* [Tune etcd][tuning].\n\n[documentation]: https://etcd.io/docs/latest\n[api]: https://etcd.io/docs/latest/learning/api\n[clustering]: https://etcd.io/docs/latest/op-guide/clustering\n[configuration]: https://etcd.io/docs/latest/op-guide/configuration\n[integrations]: https://etcd.io/docs/latest/integrations\n[security]: https://etcd.io/docs/latest/op-guide/security\n[tuning]: https://etcd.io/docs/latest/tuning\n\n## Contact\n\n* Email: [etcd-dev](https://groups.google.com/g/etcd-dev)\n* Slack: [#sig-etcd](https://kubernetes.slack.com/archives/C3HD8ARJ5) channel on Kubernetes ([get an invite](http://slack.kubernetes.io/))\n* [Community meetings](#community-meetings)\n\n### Community meetings\n\netcd contributors and maintainers meet every week at `11:00` AM (USA Pacific) on Thursday and meetings alternate between community meetings and issue triage meetings. Meeting agendas are recorded in a [shared Google doc][shared-meeting-notes] and everyone is welcome to suggest additional topics or other agendas.\n\nIssue triage meetings are aimed at getting through our backlog of PRs and Issues. Triage meetings are open to any contributor; you don't have to be a reviewer or approver to help out! They can also be a good way to get started contributing.\n\nThe meeting lead role is rotated for each meeting between etcd maintainers or sig-etcd leads and is recorded in a [shared Google sheet][shared-rotation-sheet].\n\nMeeting recordings are uploaded to the official etcd [YouTube channel].\n\nGet calendar invitations by joining [etcd-dev](https://groups.google.com/g/etcd-dev) mailing group.\n\nJoin the CNCF-funded Zoom channel: [zoom.us/my/cncfetcdproject](https://zoom.us/my/cncfetcdproject)\n\n[shared-meeting-notes]: https://docs.google.com/document/d/16XEGyPBisZvmmoIHSZzv__LoyOeluC5a4x353CX0SIM/edit\n[shared-rotation-sheet]: https://docs.google.com/spreadsheets/d/1jodHIO7Dk2VWTs1IRnfMFaRktS9IH8XRyifOnPdSY8I/edit\n[YouTube channel]: https://www.youtube.com/@etcdio\n\n## Contributing\n\nSee [CONTRIBUTING](CONTRIBUTING.md) for details on setting up your development environment, submitting patches and the contribution workflow.\n\nPlease refer to [community-membership.md](Documentation/contributor-guide/community-membership.md#member) for information on becoming an etcd project member.

paxosdb paper:\n// Our implementation hinges around a powerful primitive which we call MultiOp. All other database\n// operations except for iteration are implemented as a single call to MultiOp. A MultiOp is applied atomically\n// and consists of three components:\n// 1. A list of tests called guard. Each test in guard checks a single entry in the database. It may check\n// for the absence or presence of a value, or compare with a given value. Two different tests in the guard\n// may apply to the same or different entries in the database. All tests in the guard are applied and\n// MultiOp returns the results. If all tests are true, MultiOp executes t op (see item 2 below), otherwise\n// it executes f op (see item 3 below).\n// 2. A list of database operations called t op. Each operation in the list is either an insert, delete, or\n// lookup operation, and applies to a single database entry. Two different operations in the list may apply\n// to the same or different entries in the database. These operations are executed\n// if guard evaluates to\n// true.\n// 3. A list of database operations called f op. Like t op, but executed if guard evaluates to false.\ntype TxnRequest struct {\n\t// compare is a list of predicates representing a conjunction of terms.\n\t// If the comparisons succeed, then the success requests will be processed in order,\n\t// and the response will contain their respective responses in order.\n\t// If the comparisons fail, then the failure requests will be processed in order,\n\t// and the response will contain their respective responses in order.\n\tCompare []*Compare `protobuf:\"bytes,1,rep,name=compare,proto3\" json:\"compare,omitempty\"`\n\t// success is a list of requests which will be applied when compare evaluates to true.\n\tSuccess []*RequestOp `protobuf:\"bytes,2,rep,name=success,proto3\" json:\"success,omitempty\"`\n\t// failure is a list of requests which will be applied when compare evaluates to false.\n\tFailure              []*RequestOp `protobuf:\"bytes,3,rep,name=failure,proto3\" json:\"failure,omitempty\"`\n\tXXX_NoUnkeyedLiteral struct{}     `json:\"-\"`\n\tXXX_unrecognized     []byte       `json:\"-\"`\n\tXXX_sizecache        int32        `json:\"-\"`\n}\n\nfunc (m *TxnRequest) Reset()         { *m = TxnRequest{} }\nfunc (m *TxnRequest) String() string { return proto.CompactTextString(m) }\nfunc (*TxnRequest) ProtoMessage()    {}\nfunc (*TxnRequest) Descriptor() ([]byte, []int) {\n\treturn fileDescriptor_77a6da22d6a3feb1, []int{10}\n}\nfunc (m *TxnRequest) XXX_Unmarshal(b []byte) error {\n\treturn m.Unmarshal(b)\n}\nfunc (m *TxnRequest) XXX_Marshal(b []byte, deterministic bool) ([]byte, error) {\n\tif deterministic {\n\t\treturn xxx_messageInfo_TxnRequest.Marshal(b, m, deterministic)\n\t} else {\n\t\tb = b[:cap(b)]\n\t\tn, err := m.MarshalToSizedBuffer(b)\n\t\tif err != nil {\n\t\t\treturn nil, err\n\t\t}\n\t\treturn b[:n], nil\n\t}\n}\nfunc (m *TxnRequest) XXX_Merge(src proto.Message) {\n\txxx_messageInfo_TxnRequest.Merge(m, src)\n}\nfunc (m *TxnRequest) XXX_Size() int {\n\treturn m.Size()\n}\nfunc (m *TxnRequest) XXX_DiscardUnknown() {\n\txxx_messageInfo_TxnRequest.DiscardUnknown(m)\n}\n\nvar xxx_messageInfo_TxnRequest proto.InternalMessageInfo\n\nfunc (m *TxnRequest) GetCompare() []*Compare {\n\tif m != nil {\n\t\treturn m.Compare\n\t}\n\treturn nil\n}\n\nfunc (m *TxnRequest) GetSuccess() []*RequestOp {\n\tif m != nil {\n\t\treturn m.Success\n\t}\n\treturn nil\n}\n\nfunc (m *TxnRequest) GetFailure() []*RequestOp {\n\tif m != nil {\n\t\treturn m.Failure\n\t}\n\treturn nil\n}\n\ntype TxnResponse struct {\n\tHeader *ResponseHeader `protobuf:\"bytes,1,opt,name=header,proto3\" json:\"header,omitempty\"`\n\t// succeeded is set to true if the compare evaluated to true or false otherwise.\n\tSucceeded bool `protobuf:\"varint,2,opt,name=succeeded,proto3\" json:\"succeeded,omitempty\"`\n\t// responses is a list of responses corresponding to the results from applying\n\t// success if succeeded is true or failure if succeeded is false.\n\tResponses            []*ResponseOp `protobuf:\"bytes,3,rep,name=responses,proto3\" json:\"responses,omitempty\"`\n\tXXX_NoUnkeyedLiteral struct{}      `json:\"-\"`\n\tXXX_unrecognized     []byte        `json:\"-\"`\n\tXXX_sizecache        int32         `json:\"-\"`\n}\n\nfunc (m *TxnResponse) Reset()         { *m = TxnResponse{} }\nfunc (m *TxnResponse) String() string { return proto.CompactTextString(m) }\nfunc (*TxnResponse) ProtoMessage()    {}\nfunc (*TxnResponse) Descriptor() ([]byte, []int) {\n\treturn fileDescriptor_77a6da22d6a3feb1, []int{11}\n}\nfunc (m *TxnResponse) XXX_Unmarshal(b []byte) error {\n\treturn m.Unmarshal(b)\n}\nfunc (m *TxnResponse) XXX_Marshal(b []byte, deterministic bool) ([]byte, error) {\n\tif deterministic {\n\t\treturn xxx_messageInfo_TxnResponse.Marshal(b, m, deterministic)\n\t} else {\n\t\tb = b[:cap(b)]\n\t\tn, err := m.MarshalToSizedBuffer(b)\n\t\tif err != nil {\n\t\t\treturn nil, err\n\t\t}\n\t\treturn b[:n], nil\n\t}\n}\nfunc (m *TxnResponse) XXX_Merge(src proto.Message) {\n\txxx_messageInfo_TxnResponse.Merge(m, src)\n}\nfunc (m *TxnResponse) XXX_Size() int {\n\treturn m.Size()\n}\nfunc (m *TxnResponse) XXX_DiscardUnknown() {\n\txxx_messageInfo_TxnResponse.DiscardUnknown(m)\n}\n\nvar xxx_messageInfo_TxnResponse proto.InternalMessageInfo\n\nfunc (m *TxnResponse) GetHeader() *ResponseHeader {\n\tif m != nil {\n\t\treturn m.Header\n\t}\n\treturn nil\n}\n\nfunc (m *TxnResponse) GetSucceeded() bool {\n\tif m != nil {\n\t\treturn m.Succeeded\n\t}\n\treturn false\n}\n\nfunc (m *TxnResponse) GetResponses() []*ResponseOp {\n\tif m != nil {\n\t\treturn m.Responses\n\t}\n\treturn nil\n}\n\n// CompactionRequest compacts the key-value store up to a given revision.

All other database\n// operations except for iteration are implemented as a single call to MultiOp. A MultiOp is applied atomically\n// and consists of three components:\n// 1. A list of tests called guard. Each test in guard checks a single entry in the database. It may check\n// for the absence or presence of a value, or compare with a given value. Two different tests in the guard\n// may apply to the same or different entries in the database. All tests in the guard are applied and\n// MultiOp returns the results. If all tests are true, MultiOp executes t op (see item 2 below), otherwise\n// it executes f op (see item 3 below).\n// 2. A list of database operations called t op. Each operation in the list is either an insert, delete, or\n// lookup operation, and applies to a single database entry. Two different operations in the list may apply\n// to the same or different entries in the database. These operations are executed\n// if guard evaluates to\n// true.\n// 3.

    "content": "# etcd/client/v3\n\n[![Docs](https://img.shields.io/badge/docs-latest-green.svg)](https://etcd.io/docs)\n[![Godoc](https://img.shields.io/badge/go-documentation-blue.svg?style=flat-square)](https://godoc.org/go.etcd.io/etcd/client/v3)\n\n`etcd/clientv3` is the official Go etcd client for v3.\n\n## Install\n\n```bash\ngo get go.etcd.io/etcd/client/v3\n```\n\n## Get started\n\nCreate client using `clientv3.New`:\n\n```go\nimport clientv3 \"go.etcd.io/etcd/client/v3\"\n\nfunc main() {\n\tcli, err := clientv3.New(clientv3.Config{\n\t\tEndpoints:   []string{\"localhost:2379\", \"localhost:22379\", \"localhost:32379\"},\n\t\tDialTimeout: 5 * time.Second,\n\t})\n\tif err != nil {\n\t\t// handle error!\n\t}\n\tdefer cli.Close()\n}\n```\n\netcd v3 uses [`gRPC`](https://www.grpc.io) for remote procedure calls. And `clientv3` uses\n[`grpc-go`](https://github.com/grpc/grpc-go) to connect to etcd. Make sure to close the client after using it.\nIf the client is not closed, the connection will have leaky goroutines. To specify client request timeout,\npass `context.WithTimeout` to APIs:\n\n```go\nctx, cancel := context.WithTimeout(context.Background(), timeout)\nresp, err := cli.Put(ctx, \"sample_key\", \"sample_value\")\ncancel()\nif err != nil {\n    // handle error!\n}\n// use the response\n```\n\nFor full compatibility, it is recommended to install released versions of clients using go modules.\n\n## Error Handling\n\netcd client returns 2 types of errors:\n\n1. context error: canceled or deadline exceeded.\n2. gRPC error: see [api/v3rpc/rpctypes](https://godoc.org/go.etcd.io/etcd/api/v3rpc/rpctypes).\n\nHere is the example code to handle client errors:\n\n```go\nresp, err := cli.Put(ctx, \"\", \"\")\nif err != nil {\n\tswitch err {\n\tcase context.Canceled:\n\t\tlog.Fatalf(\"ctx is canceled by another routine: %v\", err)\n\tcase context.DeadlineExceeded:\n\t\tlog.Fatalf(\"ctx is attached with a deadline is exceeded: %v\", err)\n\tcase rpctypes.ErrEmptyKey:\n\t\tlog.Fatalf(\"client-side error: %v\", err)\n\tdefault:\n\t\tlog.Fatalf(\"bad cluster endpoints, which are not etcd servers: %v\", err)\n\t}\n}\n```\n\n## Metrics\n\nThe etcd client optionally exposes RPC metrics through [go-grpc-prometheus](https://github.com/grpc-ecosystem/go-grpc-prometheus). See the [examples](https://github.com/etcd-io/etcd/blob/main/tests/integration/clientv3/examples/example_metrics_test.go).\n\n## Namespacing\n\nThe [namespace](https://godoc.org/go.etcd.io/etcd/client/v3/namespace) package provides `clientv3` interface wrappers to transparently isolate client requests to a user-defined prefix.\n\n## Request size limit\n\nClient request size limit is configurable via `clientv3.Config.MaxCallSendMsgSize` and `MaxCallRecvMsgSize` in bytes. If none given, client request send limit defaults to 2 MiB including gRPC overhead bytes. And receive limit defaults to `math.MaxInt32`.\n\n## Examples\n\nMore code [examples](https://github.com/etcd-io/etcd/tree/main/tests/integration/clientv3/examples) can be found at [GoDoc](https://pkg.go.dev/go.etcd.io/etcd/client/v3).\n"

    "content": "# What is this?\nThis directory provides an executable example of the scenarios described in [the article by Martin Kleppmann][fencing].\n\nGenerally speaking, a lease-based lock service cannot provide mutual exclusion to processes. This is because such a lease mechanism depends on the physical clock of both the lock service and client processes. Many factors (e.g. stop-the-world GC pause of a language runtime) can cause false expiration of a granted lease as depicted in the below figure: ![unsafe lock][unsafe-lock]\n\nAs discussed in [notes on the usage of lock and lease][why], such a problem can be solved with a technique called version number validation or fencing tokens. With this technique a shared resource (storage in the figures) needs to validate requests from clients based on their tokens like this: ![fencing tokens][fencing-tokens]\n\nThis directory contains two programs: `client` and `storage`. With `etcd`, you can reproduce the expired lease problem of distributed locking and a simple example solution of the validation technique which can avoid incorrect access from a client with an expired lease.\n\n`storage` works as a very simple key value in-memory store which is accessible through HTTP and a custom JSON protocol. `client` works as client processes which tries to write a key/value to `storage` with coordination of etcd locking.\n\n## How to build\n\nFor building `client` and `storage`, just execute `go build` in each directory.\n\n## How to try\n\nAt first, you need to start an etcd cluster, which works as lock service in the figures. On top of the etcd source directory, execute commands like below:\n```\n$ make      # build etcd\n$ bin/etcd  # start etcd\n```\n\nThen run `storage` command in `storage` directory:\n```\n$ ./storage\n```\n\nNow client processes (\"Client 1\" and \"Client 2\" in the figures) can be started. At first, execute below command for starting a client process which corresponds to \"Client 1\":\n```\n$ ./client 1\n```\nIt will show an output like this:\n```\nclient 1 starts\ncreated etcd client and session\nacquired lock, version: 694d82254d5fa305\nplease manually revoke the lease using 'etcdctl lease revoke 694d82254d5fa305' or wait for it to expire, then start executing client 2 and hit any key...\n```\n\nVerify the lease was created using:\n```\n$ bin/etcdctl lease list\nfound 1 leases\n694d82254d5fa305\n```\n\nThen proceed to manually revoke the lease using:\n```\n$ bin/etcdctl lease revoke 694d82254d5fa305\nlease 694d82254d5fa305 revoked\n```\n\nNow another client process can be started like this:\n```\n$ ./client 2\nclient 2 starts\ncreated etcd client and session\nacquired lock, version: 694d82254e18770a\nthis is client 2, continuing\n```\nIf things go well the second client process invoked as `./client 2` finishes soon. It successfully writes a key to `storage` process. \n\nAfter checking this, please hit any key for `./client 1` and resume the process. It will show an output like below:\n```\nresuming client 1\nexpected fail to write to storage with old lease version: error: given version (694d82254d5fa305) is different from the existing version (694d82254e18770a)\n```\n\n[fencing]: https://martin.kleppmann.com/2016/02/08/how-to-do-distributed-locking.html\n[fencing-tokens]: https://martin.kleppmann.com/2016/02/fencing-tokens.png\n[unsafe-lock]: https://martin.kleppmann.com/2016/02/unsafe-lock.png\n[why]: https://etcd.io/docs/next/learning/why/#notes-on-the-usage-of-lock-and-lease\n"

    "content": "# raftexample\n\nraftexample is an example usage of etcd's [raft library](https://github.com/etcd-io/raft). It provides a simple REST API for a key-value store cluster backed by the [Raft][raft] consensus algorithm.\n\n[raft]: http://raftconsensus.github.io/\n\n## Getting Started\n\n### Building raftexample\n\nClone `etcd` to `<directory>/src/go.etcd.io/etcd`\n\n```sh\nexport GOPATH=<directory>\ncd <directory>/src/go.etcd.io/etcd/contrib/raftexample\ngo build -o raftexample\n```\n\n### Running single node raftexample\n\nFirst start a single-member cluster of raftexample:\n\n```sh\nraftexample --id 1 --cluster http://127.0.0.1:12379 --port 12380\n```\n\nEach raftexample process maintains a single raft instance and a key-value server.\nThe process's list of comma separated peers (--cluster), its raft ID index into the peer list (--id), and http key-value server port (--port) are passed through the command line.\n\nNext, store a value (\"hello\") to a key (\"my-key\"):\n\n```\ncurl -L http://127.0.0.1:12380/my-key -XPUT -d hello\n```\n\nFinally, retrieve the stored key:\n\n```\ncurl -L http://127.0.0.1:12380/my-key\n```\n\n### Running a local cluster\n\nFirst install [goreman](https://github.com/mattn/goreman), which manages Procfile-based applications.\n\nThe [Procfile script](./Procfile) will set up a local example cluster. Start it with:\n\n```sh\ngoreman start\n```\n\nThis will bring up three raftexample instances.\n\nNow it's possible to write a key-value pair to any member of the cluster and likewise retrieve it from any member.\n\n### Fault Tolerance\n\nTo test cluster recovery, first start a cluster and write a value \"foo\":\n```sh\ngoreman start\ncurl -L http://127.0.0.1:12380/my-key -XPUT -d foo\n```\n\nNext, remove a node and replace the value with \"bar\" to check cluster availability:\n\n```sh\ngoreman run stop raftexample2\ncurl -L http://127.0.0.1:12380/my-key -XPUT -d bar\ncurl -L http://127.0.0.1:32380/my-key\n```\n\nFinally, bring the node back up and verify it recovers with the updated value \"bar\":\n```sh\ngoreman run start raftexample2\ncurl -L http://127.0.0.1:22380/my-key\n```\n\n### Dynamic cluster reconfiguration\n\nNodes can be added to or removed from a running cluster using requests to the REST API.\n\nFor example, suppose we have a 3-node cluster that was started with the commands:\n```sh\nraftexample --id 1 --cluster http://127.0.0.1:12379,http://127.0.0.1:22379,http://127.0.0.1:32379 --port 12380\nraftexample --id 2 --cluster http://127.0.0.1:12379,http://127.0.0.1:22379,http://127.0.0.1:32379 --port 22380\nraftexample --id 3 --cluster http://127.0.0.1:12379,http://127.0.0.1:22379,http://127.0.0.1:32379 --port 32380\n```\n\nA fourth node with ID 4 can be added by issuing a POST:\n```sh\ncurl -L http://127.0.0.1:12380/4 -XPOST -d http://127.0.0.1:42379\n```\n\nThen the new node can be started as the others were, using the --join option:\n```sh\nraftexample --id 4 --cluster http://127.0.0.1:12379,http://127.0.0.1:22379,http://127.0.0.1:32379,http://127.0.0.1:42379 --port 42380 --join\n```\n\nThe new node should join the cluster and be able to service key/value requests.\n\nWe can remove a node using a DELETE request:\n```sh\ncurl -L http://127.0.0.1:12380/3 -XDELETE\n```\n\nNode 3 should shut itself down once the cluster has processed this request.\n\n## Design\n\nThe raftexample consists of three components: a raft-backed key-value store, a REST API server, and a raft consensus server based on etcd's raft implementation.\n\nThe raft-backed key-value store is a key-value map that holds all committed key-values.\nThe store bridges communication between the raft server and the REST server.\nKey-value updates are issued through the store to the raft server.\nThe store updates its map once raft reports the updates are committed.\n\nThe REST server exposes the current raft consensus by accessing the raft-backed key-value store.\nA GET command looks up a key in the store and returns the value, if any.\nA key-value PUT command issues an update proposal to the store.\n\nThe raft server participates in consensus with its cluster peers.\nWhen the REST server submits a proposal, the raft server transmits the proposal to its peers.\nWhen raft reaches a consensus, the server publishes all committed updates over a commit channel.\nFor raftexample, this commit channel is consumed by the key-value store.\n\n"

For the v2 API, make sure to set environment variable `ETCDCTL_API=2`. See also [READMEv2][READMEv2].\n\nIf using released versions earlier than v3.4, set `ETCDCTL_API=3` to use v3 API.\n\nGlobal flags (e.g., `dial-timeout`, `--cacert`, `--cert`, `--key`) can be set with environment variables:\n\n```\nETCDCTL_DIAL_TIMEOUT=3s\nETCDCTL_CACERT=/tmp/ca.pem\nETCDCTL_CERT=/tmp/cert.pem\nETCDCTL_KEY=/tmp/key.pem\n```\n\nPrefix flag strings with `ETCDCTL_`, convert all letters to upper-case, and replace dash(`-`) with underscore(`_`). Note that the environment variables with the prefix `ETCDCTL_` can only be used with the etcdctl global flags. Also, the environment variable `ETCDCTL_API` is a special case variable for etcdctl internal use only.\n\n## Key-value commands\n\n### PUT [options] \\<key\\> \\<value\\>\n\nPUT assigns the specified value with the specified key. If key already holds a value, it is overwritten.\n\nRPC: Put\n\n#### Options\n\n- lease -- lease ID (in hexadecimal) to attach to the key.\n\n- prev-kv -- return the previous key-value pair before modification.\n\n- ignore-value -- updates the key using its current value.\n\n- ignore-lease -- updates the key using its current lease.\n\n#### Output\n\n`OK`\n\n#### Examples\n\n```bash\n./etcdctl put foo bar --lease=1234abcd\n# OK\n./etcdctl get foo\n# foo\n# bar\n./etcdctl put foo --ignore-value # to detache lease\n# OK\n```\n\n```bash\n./etcdctl put foo bar --lease=1234abcd\n# OK\n./etcdctl put foo bar1 --ignore-lease # to use existing lease 1234abcd\n# OK\n./etcdctl get foo\n# foo\n# bar1\n```\n\n```bash\n./etcdctl put foo bar1 --prev-kv\n# OK\n# foo\n# bar\n./etcdctl get foo\n# foo\n# bar1\n```\n\n#### Remarks\n\nIf \\<value\\> isn't given as command line argument, this command tries to read the value from standard input.\n\nWhen \\<value\\> begins with '-', \\<value\\> is interpreted as a flag.\nInsert '--' for workaround:\n\n```bash\n./etcdctl put <key> -- <value>\n./etcdctl put -- <key> <value>\n```\n\nProviding \\<value\\> in a new line after using `carriage return` is not supported and etcdctl may hang in that case. For example, following case is not supported:\n\n```bash\n./etcdctl put <key>\\r\n<value>\n```\n\nA \\<value\\> can have multiple lines or spaces but it must be provided with a double-quote as demonstrated below:\n\n```bash\n./etcdctl put foo \"bar1 2 3\"\n```\n\n### GET [options] \\<key\\> [range_end]\n\nGET gets the key or a range of keys [key, range_end) if range_end is given.\n\nRPC: Range\n\n#### Options\n\n- hex -- print out key and value as hex encode string\n\n- limit -- maximum number of results\n\n- prefix -- get keys by matching prefix\n\n- order -- order of results; ASCEND or DESCEND\n\n- sort-by -- sort target; CREATE, KEY, MODIFY, VALUE, or VERSION\n\n- rev -- specify the kv revision\n\n- print-value-only -- print only value when used with write-out=simple\n\n- consistency -- Linearizable(l) or Serializable(s), defaults to Linearizable(l).\n\n- from-key -- Get keys that are greater than or equal to the given key using byte compare\n\n- keys-only -- Get only the keys\n\n- max-create-revision -- restrict results to kvs with create revision lower or equal than the supplied revision\n\n- min-create-revision -- restrict results to kvs with create revision greater or equal than the supplied revision\n\n- max-mod-revision -- restrict results to kvs with modified revision lower or equal than the supplied revision\n\n- min-mod-revision -- restrict results to kvs with modified revision greater or equal than the supplied revision\n\n#### Output\n\nPrints the data in format below,\n\n```\n\\<key\\>\\n\\<value\\>\\n\\<next_key\\>\\n\\<next_value\\>...\n```\n\nNote serializable requests are better for lower latency requirement, but\nstale data might be returned if serializable option (`--consistency=s`)\nis specified.\n\n#### Examples\n\nFirst, populate etcd with some keys:\n\n```bash\n./etcdctl put foo bar\n# OK\n./etcdctl put foo1 bar1\n# OK\n./etcdctl put foo2 bar2\n# OK\n./etcdctl put foo3 bar3\n# OK\n```\n\nGet the key named `foo`:\n\n```bash\n./etcdctl get foo\n# foo\n# bar\n```\n\nGet all keys:\n\n```bash\n./etcdctl get --from-key ''\n# foo\n# bar\n# foo1\n# bar1\n# foo2\n# foo2\n# foo3\n# bar3\n```\n\nGet all keys with names greater than or equal to `foo1`:\n\n```bash\n./etcdctl get --from-key foo1\n# foo1\n# bar1\n# foo2\n# bar2\n# foo3\n# bar3\n```\n\nGet keys with names greater than or equal to `foo1` and less than `foo3`:\n\n```bash\n./etcdctl get foo1 foo3\n# foo1\n# bar1\n# foo2\n# bar2\n```\n\n#### Remarks\n\nIf any key or value contains non-printable characters or control characters, simple formatted output can be ambiguous due to new lines. To resolve this issue, set `--hex` to hex encode all strings.\n\n### DEL [options] \\<key\\> [range_end]\n\nRemoves the specified key or range of keys [key, range_end) if range_end is given.\n\nRPC: DeleteRange\n\n#### Options\n\n- prefix -- delete keys by matching prefix\n\n- prev-kv -- return deleted key-value pairs\n\n- from-key -- delete keys that are greater than or equal to the given key using byte compare\n\n#### Output\n\nPrints the number of keys that were removed in decimal if DEL succeeded.\n\n#### Examples\n\n```bash\n./etcdctl put foo bar\n# OK\n./etcdctl del foo\n# 1\n./etcdctl get foo\n```\n\n```bash\n./etcdctl put key val\n# OK\n./etcdctl del --prev-kv key\n# 1\n# key\n# val\n./etcdctl get key\n```\n\n```bash\n./etcdctl put a 123\n# OK\n./etcdctl put b 456\n# OK\n./etcdctl put z 789\n# OK\n./etcdctl del --from-key a\n# 3\n./etcdctl get --from-key a\n```\n\n```bash\n./etcdctl put zoo val\n# OK\n./etcdctl put zoo1 val1\n# OK\n./etcdctl put zoo2 val2\n# OK\n./etcdctl del --prefix zoo\n# 3\n./etcdctl get zoo2\n```\n\n### TXN [options]\n\nTXN reads multiple etcd requests from standard input and applies them as a single atomic transaction.\nA transaction consists of list of conditions, a list of requests to apply if all the conditions are true, and a list of requests to apply if any condition is false.\n\nRPC: Txn\n\n#### Options\n\n- hex -- print out keys and values as hex encoded strings.\n\n- interactive -- input transaction with interactive prompting.\n\n#### Input Format\n\n```ebnf\n<Txn> ::= <CMP>* \"\\n\" <THEN> \"\\n\" <ELSE> \"\\n\"\n<CMP> ::= (<CMPCREATE>|<CMPMOD>|<CMPVAL>|<CMPVER>|<CMPLEASE>) \"\\n\"\n<CMPOP> ::= \"<\" | \"=\" | \">\"\n<CMPCREATE> := (\"c\"|\"create\")\"(\"<KEY>\")\" <CMPOP> <REVISION>\n<CMPMOD> ::= (\"m\"|\"mod\")\"(\"<KEY>\")\" <CMPOP> <REVISION>\n<CMPVAL> ::= (\"val\"|\"value\")\"(\"<KEY>\")\" <CMPOP> <VALUE>\n<CMPVER> ::= (\"ver\"|\"version\")\"(\"<KEY>\")\" <CMPOP> <VERSION>\n<CMPLEASE> ::= \"lease(\"<KEY>\")\" <CMPOP> <LEASE>\n<THEN> ::= <OP>*\n<ELSE> ::= <OP>*\n<OP> ::= ((see put, get, del etcdctl command syntax)) \"\\n\"\n<KEY> ::= (%q formatted string)\n<VALUE> ::= (%q formatted string)\n<REVISION> ::= \"\\\"\"[0-9]+\"\\\"\"\n<VERSION> ::= \"\\\"\"[0-9]+\"\\\"\"\n<LEASE> ::= \"\\\"\"[0-9]+\\\"\"\n```\n\n#### Output\n\n`SUCCESS` if etcd processed the transaction success list, `FAILURE` if etcd processed the transaction failure list. Prints the output for each command in the executed request list, each separated by a blank line.\n\n#### Examples\n\ntxn in interactive mode:\n\n```bash\n./etcdctl txn -i\n# compares:\nmod(\"key1\") > \"0\"\n\n# success requests (get, put, delete):\nput key1 \"overwrote-key1\"\n\n# failure requests (get, put, delete):\nput key1 \"created-key1\"\nput key2 \"some extra key\"\n\n# FAILURE\n\n# OK\n\n# OK\n```\n\ntxn in non-interactive mode:\n\n```bash\n./etcdctl txn <<<'mod(\"key1\") > \"0\"\n\nput key1 \"overwrote-key1\"\n\nput key1 \"created-key1\"\nput key2 \"some extra key\"\n\n'\n\n# FAILURE\n\n# OK\n\n# OK\n```\n\n#### Remarks\n\nWhen using multi-line values within a TXN command, newlines must be represented as `\\n`. Literal newlines will cause parsing failures. This differs from other commands (such as PUT) where the shell will convert literal newlines for us. For example:\n\n```bash\n./etcdctl txn <<<'mod(\"key1\") > \"0\"\n\nput key1 \"overwrote-key1\"\n\nput key1 \"created-key1\"\nput key2 \"this is\\na multi-line\\nvalue\"\n\n'\n\n# FAILURE\n\n# OK\n\n# OK\n```\n\n### COMPACTION [options] \\<revision\\>\n\nCOMPACTION discards all etcd event history prior to a given revision. Since etcd uses a multiversion concurrency control\nmodel, it preserves all key updates as event history. When the event history up to some revision is no longer needed,\nall superseded keys may be compacted away to reclaim storage space in the etcd backend database.\n\nRPC: Compact\n\n#### Options\n\n- physical -- 'true' to wait for compaction to physically remove all old revisions\n\n#### Output\n\nPrints the compacted revision.\n\n#### Example\n\n```bash\n./etcdctl compaction 1234\n# compacted revision 1234\n```\n\n### WATCH [options] [key or prefix] [range_end] [--] [exec-command arg1 arg2 ...]\n\nWatch watches events stream on keys or prefixes, [key or prefix, range_end) if range_end is given. The watch command runs until it encounters an error or is terminated by the user. If range_end is given, it must be lexicographically greater than key or \"\\x00\".\n\nRPC: Watch\n\n#### Options\n\n- hex -- print out key and value as hex encode string\n\n- interactive -- begins an interactive watch session\n\n- prefix -- watch on a prefix if prefix is set.\n\n- prev-kv -- get the previous key-value pair before the event happens.\n\n- rev -- the revision to start watching. Specifying a revision is useful for observing past events.\n\n#### Input format\n\nInput is only accepted for interactive mode.\n\n```\nwatch [options] <key or prefix>\\n\n```\n\n#### Output\n\n\\<event\\>[\\n\\<old_key\\>\\n\\<old_value\\>]\\n\\<key\\>\\n\\<value\\>\\n\\<event\\>\\n\\<next_key\\>\\n\\<next_value\\>\\n...\n\n#### Examples\n\n##### Non-interactive\n\n```bash\n./etcdctl watch foo\n# PUT\n# foo\n# bar\n```\n\n```bash\nETCDCTL_WATCH_KEY=foo ./etcdctl watch\n# PUT\n# foo\n# bar\n```\n\nReceive events and execute `echo watch event

membership.\n\n### MEMBER ADD \\<memberName\\> [options]\n\nMEMBER ADD introduces a new member into the etcd cluster as a new peer.\n\nRPC: MemberAdd\n\n#### Options\n\n- peer-urls -- comma separated list of URLs to associate with the new member.\n\n#### Output\n\nPrints the member ID of the new member and the cluster ID.\n\n#### Example\n\n```bash\n./etcdctl member add newMember --peer-urls=https://127.0.0.1:12345\n\nMember ced000fda4d05edf added to cluster 8c4281cc65c7b112\n\nETCD_NAME=\"newMember\"\nETCD_INITIAL_CLUSTER=\"newMember=https://127.0.0.1:12345,default=http://10.0.0.30:2380\"\nETCD_INITIAL_CLUSTER_STATE=\"existing\"\n```\n\n### MEMBER UPDATE \\<memberID\\> [options]\n\nMEMBER UPDATE sets the peer URLs for an existing member in the etcd cluster.\n\nRPC: MemberUpdate\n\n#### Options\n\n- peer-urls -- comma separated list of URLs to associate with the updated member.\n\n#### Output\n\nPrints the member ID of the updated member and the cluster ID.\n\n#### Example\n\n```bash\n./etcdctl member update 2be1eb8f84b7f63e

participating in cluster consensus.\n\nRPC: MemberRemove\n\n#### Output\n\nPrints the member ID of the removed member and the cluster ID.\n\n#### Example\n\n```bash\n./etcdctl member remove 2be1eb8f84b7f63e\n# Member 2be1eb8f84b7f63e removed from cluster ef37ad9dc622a7c4\n```\n\n### MEMBER LIST\n\nMEMBER LIST prints the member details for all members associated with an etcd cluster.\n\nRPC: MemberList\n\n#### Options\n\n- consistency -- Linearizable(l) or Serializable(s), defaults to Linearizable(l).\n\n#### Output\n\nPrints a humanized table of the member IDs, statuses, names, peer addresses, and client addresses.\n\nNote serializable requests are better for lower latency requirement, but\nstale member list might be returned if serializable option (`--consistency=s`)\nis specified. In some situations users may want to use serializable requests.\nFor example, when adding a new member to a one-node cluster, it's reasonable\nand safe to use serializable request before the new added member gets started.\n\n#### Examples\n\n```bash\n./etcdctl member list\n# 8211f1d0f64f3269, started, infra1, http://127.0.0.1:12380, http://127.0.0.1:2379\n# 91bc3c398fb3c146, started, infra2, http://127.0.0.1:22380, http://127.0.0.1:22379\n# fd422379fda50e48, started, infra3, http://127.0.0.1:32380, http://127.0.0.1:32379\n```\n\n```bash\n./etcdctl -w json member list\n# {\"header\":{\"cluster_id\":17237436991929493444,\"member_id\":9372538179322589801,\"raft_term\":2},\"members\":[{\"ID\":9372538179322589801,\"name\":\"infra1\",\"peerURLs\":[\"http://127.0.0.1:12380\"],\"clientURLs\":[\"http://127.0.0.1:2379\"]},{\"ID\":10501334649042878790,\"name\":\"infra2\",\"peerURLs\":[\"http://127.0.0.1:22380\"],\"clientURLs\":[\"http://127.0.0.1:22379\"]},{\"ID\":18249187646912138824,\"name\":\"infra3\",\"peerURLs\":[\"http://127.0.0.1:32380\"],\"clientURLs\":[\"http://127.0.0.1:32379\"]}]}\n```\n\n```bash\n./etcdctl -w table member list\n+------------------+---------+--------+------------------------+------------------------+\n|        ID        | STATUS  |  NAME  |       PEER ADDRS       |      CLIENT ADDRS      |\n+------------------+---------+--------+------------------------+------------------------+\n| 8211f1d0f64f3269 | started | infra1 | http://127.0.0.1:12380 | http://127.0.0.1:2379  |\n| 91bc3c398fb3c146 | started | infra2 | http://127.0.0.1:22380 | http://127.0.0.1:22379 |\n| fd422379fda50e48 | started | infra3 | http://127.0.0.1:32380 | http://127.0.0.1:32379 |\n+------------------+---------+--------+------------------------+------------------------+\n```\n\n### ENDPOINT \\<subcommand\\>\n\nENDPOINT provides commands for querying individual endpoints.\n\n#### Options\n\n- cluster -- fetch and use all endpoints from the etcd cluster member list\n\n### ENDPOINT HEALTH\n\nENDPOINT HEALTH checks the health of the list of endpoints with respect to cluster. An endpoint is unhealthy\nwhen it cannot participate in consensus with the rest of the cluster.\n\n#### Output\n\nIf an endpoint can participate in consensus, prints a message indicating the endpoint is healthy. If an endpoint fails to participate in consensus, prints a message indicating the endpoint is unhealthy.\n\n#### Example\n\nCheck the default endpoint's health:\n\n```bash\n./etcdctl endpoint

DISARM\n\n`alarm disarm` Disarms all alarms\n\nRPC: Alarm\n\n#### Output\n\n`alarm:<alarm type>` if alarm is present and disarmed.\n\n#### Examples\n\n```bash\n./etcdctl alarm disarm\n```\n\nIf NOSPACE alarm is present:\n\n```bash\n./etcdctl alarm disarm\n# alarm:NOSPACE\n```\n\n### ALARM LIST\n\n`alarm list` lists all alarms.\n\nRPC: Alarm\n\n#### Output\n\n`alarm:<alarm type>` if alarm is present, empty string if no alarms present.\n\n#### Examples\n\n```bash\n./etcdctl alarm list\n```\n\nIf NOSPACE alarm is present:\n\n```bash\n./etcdctl alarm list\n# alarm:NOSPACE\n```\n\n### DEFRAG [options]\n\nDEFRAG defragments the backend database file for a set of given endpoints while etcd is running. When an etcd member reclaims storage space from deleted and compacted keys, the space is kept in a free list and the database file remains the same size. By defragmenting the database, the etcd member releases this free space back to the file system.\n\n**Note: to defragment offline (`--data-dir` flag), use: `etcutl defrag` instead**\n\n**Note that defragmentation to a live member blocks the system from reading and writing data while rebuilding its states.**\n\n**Note that defragmentation request does not get replicated over cluster. That is, the request is only applied to the local node. Specify all members in `--endpoints` flag or `--cluster` flag to automatically find all cluster members.**\n\n#### Output\n\nFor each endpoints, prints a message indicating whether the endpoint was successfully defragmented.\n\n#### Example\n\n```bash\n./etcdctl --endpoints=localhost:2379,badendpoint:2379 defrag\n# Finished defragmenting etcd member[localhost:2379]\n# Failed to defragment etcd member[badendpoint:2379] (grpc: timed out trying to connect)\n```\n\nRun defragment operations for all endpoints in the cluster associated with the default endpoint:\n\n```bash\n./etcdctl defrag --cluster\nFinished defragmenting etcd member[http://127.0.0.1:2379]\nFinished defragmenting etcd member[http://127.0.0.1:22379]\nFinished defragmenting etcd member[http://127.0.0.1:32379]\n```\n\n#### Remarks\n\nDEFRAG returns a zero exit code only if it succeeded defragmenting all given endpoints.\n\n### SNAPSHOT \\<subcommand\\>\n\nSNAPSHOT provides commands to restore a snapshot of a running etcd server into a fresh cluster.\n\n### SNAPSHOT SAVE \\<filename\\>\n\nSNAPSHOT SAVE writes a point-in-time snapshot of the etcd backend database to a file.\n\n#### Output\n\nThe backend snapshot is written to the given file path.\n\n#### Example\n\nSave a snapshot to \"snapshot.db\":\n\n```\n./etcdctl snapshot save snapshot.db\n```\n\n### SNAPSHOT RESTORE [options] \\<filename\\>\n\nRemoved in v3.6. Use `etcdutl snapshot restore` instead.\n\n### SNAPSHOT STATUS \\<filename\\>\n\nRemoved in v3.6. Use `etcdutl snapshot status` instead.\n\n### MOVE-LEADER \\<hexadecimal-transferee-id\\>\n\nMOVE-LEADER transfers leadership from the leader to another member in the cluster.\n\n#### Example\n\n```bash\n# to choose transferee\ntransferee_id=$(./etcdctl \\\n  --endpoints localhost:2379,localhost:22379,localhost:32379 \\\n  endpoint status | grep -m 1 \"false\" | awk -F', ' '{print $2}')\necho ${transferee_id}\n# c89feb932daef420\n\n# endpoints should include leader node\n./etcdctl --endpoints ${transferee_ep} move-leader ${transferee_id}\n# Error:  no leader endpoint given at [localhost:22379 localhost:32379]\n\n# request to leader with target node ID\n./etcdctl --endpoints ${leader_ep} move-leader ${transferee_id}\n# Leadership transferred from 45ddc0e800e20b93 to c89feb932daef420\n```\n\n### DOWNGRADE \\<subcommand\\>\n\nNOTICE: Downgrades is an experimental feature in v3.6 and is not recommended for production clusters.\n\nDowngrade provides commands to downgrade cluster.\nNormally etcd members cannot be downgraded due to cluster version mechanism.\n\nAfter initial bootstrap, cluster members agree on the cluster version. Every 5 seconds, leader checks versions of all members and picks lowers minor version.\nNew members will refuse joining cluster with cluster version newer than theirs, thus preventing cluster from downgrading.\nDowngrade commands allow cluster administrator to force cluster version to be lowered to previous minor version, thus allowing to downgrade the cluster.\n\nDowngrade should be executed in stages:\n\n1. Verify that cluster is ready to be downgraded by running `etcdctl downgrade validate <TARGET_VERSION>`\n2. Start the downgrade process by running `etcdctl downgrade enable <TARGET_VERSION>`\n3. For each cluster member:\n   1. Ensure that member is ready for downgrade by confirming that it wrote `The server is ready to downgrade` log.\n   2. Replace member binary with one with older version.\n   3. Confirm that member has correctly started and joined the cluster.\n4. Ensure that downgrade process has succeeded by checking leader log for `the cluster has been downgraded`\n\nDowngrade can be canceled by running `etcdctl downgrade cancel` command.\n\nIn case of downgrade being canceled, cluster version will return to its normal behavior (pick the lowest member minor version).\nIf no members were downgraded, cluster version will return to original value.\nIf at least one member was downgraded, cluster version will stay at the `<TARGET_VALUE>` until downgraded members are upgraded back.\n\n### DOWNGRADE VALIDATE \\<TARGET_VERSION\\>\n\nDOWNGRADE VALIDATE validate downgrade capability before starting downgrade.\n\n#### Example\n\n```bash\n./etcdctl downgrade validate 3.5\nDowngrade validate success, cluster version 3.6\n\n./etcdctl downgrade validate 3.4\nError: etcdserver: invalid downgrade target version\n\n```\n\n### DOWNGRADE ENABLE \\<TARGET_VERSION\\>\n\nDOWNGRADE ENABLE starts a downgrade action to cluster.\n\n#### Example\n\n```bash\n./etcdctl downgrade enable 3.5\nDowngrade enable success, cluster version 3.6\n```\n\n### DOWNGRADE CANCEL\n\nDOWNGRADE CANCEL cancels the ongoing downgrade action to cluster.\n\n#### Example\n\n```bash\n./etcdctl downgrade cancel\nDowngrade cancel success, cluster version 3.5\n```\n\n### DIAGNOSIS\n\n`etcdctl diagnosis [flags]` - Collects and analyzes troubleshooting data from a running etcd cluster.\n\nThe `diagnosis` command gathers a concise set of diagnostic details from each cluster member by performing several checks, including:\n\n  * **Membership checks**: Verifies the cluster membership information.\n  * **Endpoint status**: Retrieves the status of each endpoint.\n  * **Serializable and linearizable reads**: Performs read operations to validate data consistency.\n  * **Metrics snapshot**: Collects a small snapshot of key metrics.\n\n#### Flags\n\n- `--cluster`: use all endpoints discovered from the cluster member list.\n- `--etcd-storage-quota-bytes`: expected etcd storage quota in bytes (value passed to etcd with `--quota-backend-bytes`).\n- `-o, --output`: optional file path to write the JSON report; by default the report is written to stdout. Logs are written to stderr.\n\nGlobal flags (like `--endpoints`, TLS, auth, and timeouts) are shared with other `etcdctl` commands. See `etcdctl options` for the full list.\n\n#### Examples\n\nTo perform analysis of a running etcd cluster, you can use the following command. This will collect and analyze data from all specified endpoints.\n\n```bash\netcdctl diagnosis --endpoints=https://10.0.1.10:2379,https://10.0.1.11:2379,https://10.0.1.12:2379 \\\n  --cacert ./ca.crt --key ./etcd-diagnosis.key --cert ./etcd-diagnosis.crt\n\n# Use cluster-discovered endpoints\netcdctl diagnosis --cluster\n\n# Write report to a file (logs still go to stderr)\netcdctl diagnosis -o report.json\n```\n\n\nExample output: see [ctlv3/command/diagnosis/examples/etcd_diagnosis_report.json](ctlv3/command/diagnosis/examples/etcd_diagnosis_report.json)\n\n## Concurrency commands\n\n### LOCK [options] \\<lockname\\> [command arg1 arg2 ...]\n\nLOCK acquires a distributed mutex with a given name. Once the lock is acquired, it will be held until etcdctl is terminated.\n\n#### Options\n\n- ttl - time out in seconds of lock session.\n\n#### Output\n\nOnce the lock is acquired but no command is given, the result for the GET on the unique lock holder key is displayed.\n\nIf a command is given, it will be executed with environment variables `ETCD_LOCK_KEY` and `ETCD_LOCK_REV` set to the lock's holder key and revision.\n\n#### Example\n\nAcquire lock with standard output display:\n\n```bash\n./etcdctl lock mylock\n# mylock/1234534535445\n```\n\nAcquire lock and execute `echo lock acquired`:\n\n```bash\n./etcdctl lock mylock echo lock acquired\n# lock acquired\n```\n\nAcquire lock and execute `etcdctl put` command\n\n```bash\n./etcdctl lock mylock ./etcdctl put foo bar\n# OK\n```\n\n#### Remarks\n\nLOCK returns a zero exit code only if it is terminated by a signal and releases the lock.\n\nIf LOCK is abnormally terminated or fails to contact the cluster to release the lock, the lock will remain held until the lease expires. Progress may be delayed by up to the default lease length of 60 seconds.\n\n### ELECT [options] \\<election-name\\> [proposal]\n\nELECT participates on a named election. A node announces its candidacy in the election by providing\na proposal value. If a node wishes to observe the election, ELECT listens for new leaders values.\nWhenever a leader is elected, its proposal is given as output.\n\n#### Options\n\n- listen -- observe the election.\n\n#### Output\n\n- If a candidate, ELECT displays the GET on the leader key once the node is elected election.\n\n- If observing, ELECT streams the result for a GET on the leader key for the current election and all future elections.\n\n#### Example\n\n```bash\n./etcdctl elect myelection foo\n# myelection/1456952310051373265\n# foo\n```\n\n#### Remarks\n\nELECT returns a zero exit code only if it is terminated by a signal and can revoke its candidacy or leadership, if any.\n\nIf a candidate is abnormally terminated, election progress may be delayed by up to the default lease length of 60 seconds.\n\n## Authentication commands\n\n### AUTH \\<enable or disable\\>\n\n`auth enable` activates authentication on an etcd cluster and `auth disable` deactivates. When authentication is enabled, etcd checks all requests for appropriate authorization.\n\nRPC: AuthEnable/AuthDisable\n\n#### Output\n\n`Authentication Enabled`.\n\n#### Examples\n\n```bash\n./etcdctl user add root\n# Password of root:#type password for root\n# Type password of root again for confirmation:#re-type password for root\n# User root created\n./etcdctl user grant-role root root\n# Role root is granted to user root\n./etcdctl user get root\n# User: root\n# Roles: root\n./etcdctl role add root\n# Role root created\n./etcdctl role get root\n# Role root\n# KV Read:\n# KV Write:\n./etcdctl auth enable\n# Authentication Enabled\n```\n\n### ROLE \\<subcommand\\>\n\nROLE is used to specify different roles which can be assigned to etcd user(s).\n\n### ROLE ADD \\<role name\\>\n\n`role add` creates a role.\n\nRPC: RoleAdd\n\n#### Output\n\n`Role <role name> created`.\n\n#### Examples\n\n```bash\n./etcdctl --user=root:123 role add myrole\n# Role myrole created\n```\n\n### ROLE GET \\<role name\\>\n\n`role get` lists detailed role information.\n\nRPC: RoleGet\n\n#### Output\n\nDetailed role information.\n\n#### Examples\n\n```bash\n./etcdctl --user=root:123 role get myrole\n# Role myrole\n# KV Read:\n# foo\n# KV Write:\n# foo\n```\n\n### ROLE DELETE \\<role name\\>\n\n`role delete` deletes a role.\n\nRPC: RoleDelete\n\n#### Output\n\n`Role <role name> deleted`.\n\n#### Examples\n\n```bash\n./etcdctl --user=root:123 role delete myrole\n# Role myrole deleted\n```\n\n### ROLE LIST \\<role name\\>\n\n`role list` lists all roles in etcd.\n\nRPC: RoleList\n\n#### Output\n\nA role per line.\n\n#### Examples\n\n```bash\n./etcdctl --user=root:123 role list\n# roleA\n# roleB\n# myrole\n```\n\n### ROLE GRANT-PERMISSION [options] \\<role name\\> \\<permission type\\> \\<key\\> [endkey]\n\n`role grant-permission` grants a key to a role.\n\nRPC: RoleGrantPermission\n\n#### Options\n\n- from-key -- grant a permission of keys that are greater than or equal to the given key using byte compare\n\n- prefix -- grant a prefix permission\n\n#### Output\n\n`Role <role name> updated`.\n\n#### Examples\n\nGrant read and write permission on the key `foo` to role `myrole`:\n\n```bash\n./etcdctl --user=root:123 role grant-permission myrole readwrite foo\n# Role myrole updated\n```\n\nGrant read permission on the wildcard key pattern `foo/*` to role `myrole`:\n\n```bash\n./etcdctl --user=root:123 role grant-permission --prefix myrole readwrite foo/\n# Role myrole updated\n```\n\n### ROLE REVOKE-PERMISSION \\<role name\\> \\<permission type\\> \\<key\\> [endkey]\n\n`role revoke-permission` revokes a key from a role.\n\nRPC: RoleRevokePermission\n\n#### Options\n\n- from-key -- revoke a permission of keys that are greater than or equal to the given key using byte compare\n\n- prefix -- revoke a prefix permission\n\n#### Output\n\n`Permission of key <key> is revoked from role <role name>` for single key. `Permission of range [<key>, <endkey>) is revoked from role <role name>` for a key range. Exit code is zero.\n\n#### Examples\n\n```bash\n./etcdctl --user=root:123 role revoke-permission myrole foo\n# Permission of key foo is revoked from role myrole\n```\n\n### USER \\<subcommand\\>\n\nUSER provides commands for managing users of etcd.\n\n### USER ADD \\<user name or user:password\\> [options]\n\n`user add` creates a user.\n\nRPC: UserAdd\n\n#### Options\n\n- interactive -- Read password from stdin instead of interactive terminal\n\n#### Output\n\n`User <user name> created`.\n\n#### Examples\n\n```bash\n./etcdctl --user=root:123 user add myuser\n# Password of myuser: #type password for my user\n# Type password of myuser again for confirmation:#re-type password for my user\n# User myuser created\n```\n\n### USER GET \\<user name\\> [options]\n\n`user get` lists detailed user information.\n\nRPC: UserGet\n\n#### Options\n\n- detail -- Show permissions of roles granted to the user\n\n#### Output\n\nDetailed user information.\n\n#### Examples\n\n```bash\n./etcdctl --user=root:123 user get myuser\n# User: myuser\n# Roles:\n```\n\n### USER DELETE \\<user name\\>\n\n`user delete` deletes a user.\n\nRPC: UserDelete\n\n#### Output\n\n`User <user name> deleted`.\n\n#### Examples\n\n```bash\n./etcdctl --user=root:123 user delete myuser\n# User myuser deleted\n```\n\n### USER LIST\n\n`user list` lists detailed user information.\n\nRPC: UserList\n\n#### Output\n\n- List of users, one per line.\n\n#### Examples\n\n```bash\n./etcdctl --user=root:123 user list\n# user1\n# user2\n# myuser\n```\n\n### USER PASSWD \\<user name\\> [options]\n\n`user passwd` changes a user's password.\n\nRPC: UserChangePassword\n\n#### Options\n\n- interactive -- if true, read password in interactive terminal\n\n#### Output\n\n`Password updated`.\n\n#### Examples\n\n```bash\n./etcdctl --user=root:123 user passwd myuser\n# Password of myuser: #type new password for my user\n# Type password of myuser again for confirmation: #re-type the new password for my user\n# Password updated\n```\n\n### USER GRANT-ROLE \\<user name\\> \\<role name\\>\n\n`user grant-role` grants a role to a user\n\nRPC: UserGrantRole\n\n#### Output\n\n`Role <role name> is granted to user <user name>`.\n\n#### Examples\n\n```bash\n./etcdctl --user=root:123 user grant-role userA roleA\n# Role roleA is granted to user userA\n```\n\n### USER REVOKE-ROLE \\<user name\\> \\<role name\\>\n\n`user revoke-role` revokes a role from a user\n\nRPC: UserRevokeRole\n\n#### Output\n\n`Role <role name> is revoked from user <user name>`.\n\n#### Examples\n\n```bash\n./etcdctl --user=root:123 user revoke-role userA roleA\n# Role roleA is revoked from user userA\n```\n\n## Utility commands\n\n### MAKE-MIRROR [options] \\<destination\\>\n\n[make-mirror][mirror] mirrors a key prefix in an etcd cluster to a destination etcd cluster.\n\n#### Options\n\n- dest-cacert -- TLS certificate authority file for destination cluster\n\n- dest-cert -- TLS certificate file for destination cluster\n\n- dest-key -- TLS key file for destination cluster\n\n- prefix -- The key-value prefix to mirror\n\n- dest-prefix -- The destination prefix to mirror a prefix to a different prefix in the destination cluster\n\n- no-dest-prefix -- Mirror key-values to the root of the destination cluster\n\n- dest-insecure-transport -- Disable transport security for client connections\n\n- max-txn-ops -- Maximum number of operations permitted in a transaction during syncing updates\n\n#### Output\n\nThe approximate total number of keys transferred to the destination cluster, updated every 30 seconds.\n\n#### Examples\n\n```\n./etcdctl make-mirror mirror.example.com:2379\n# 10\n# 18\n```\n\n[mirror]: ./doc/mirror_maker.md\n\n### VERSION\n\nPrints the version of etcdctl.\n\n#### Output\n\nPrints etcd version and API version.\n\n#### Examples\n\n```bash\n./etcdctl version\n# etcdctl version: 3.1.0-alpha.0+git\n# API version: 3.1\n```\n\n### CHECK \\<subcommand\\>\n\nCHECK provides commands for checking properties of the etcd cluster.\n\n### CHECK PERF [options]\n\nCHECK PERF checks the performance of the etcd cluster for 60 seconds. Running the `check perf` often can create a large keyspace history which can be auto compacted and defragmented using the `--auto-compact` and `--auto-defrag` options as described below.\n\nNotice that different workload models use different configurations in terms of number of clients and throughput. Here is the configuration for each load:\n\n| Load | Number of clients | Number of put requests (requests/sec) |\n|---------|------|---------|\n| Small   | 50   | 10000   |\n| Medium  | 200  | 100000  |\n| Large   | 500  | 1000000 |\n| xLarge  | 1000 | 3000000 |\n\nThe test checks for the following conditions:\n\n- The throughput should be at least 90% of the issued request\n- All the requests should be done in less than 500 ms\n- The standard deviation of the requests should be less than 100 ms\n\nHence, a workload model may work while another one might fail.\n\nRPC: CheckPerf\n\n#### Options\n\n- load -- the performance check's workload model. Accepted workloads: s(small), m(medium), l(large), xl(xLarge)\n\n- prefix -- the prefix for writing the performance check's keys.\n\n- auto-compact -- if true, compact storage with last revision after test is finished.\n\n- auto-defrag -- if true, defragment storage after test is finished.\n\n#### Output\n\nPrints the result of performance check on different criteria like throughput. Also prints an overall status of the check as pass or fail.\n\n#### Examples\n\nShows examples of both, pass and fail, status. The failure is due to the fact that a large workload was tried on a single node etcd cluster running on a laptop environment created for development and testing purpose.\n\n```bash\n./etcdctl check perf --load=\"s\"\n# 60 / 60 Booooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo! 100.00%1m0s\n# PASS: Throughput is 150 writes/s\n# PASS: Slowest request took 0.087509s\n# PASS: Stddev is 0.011084s\n# PASS\n./etcdctl check perf --load=\"l\"\n# 60 / 60 Booooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo! 100.00%1m0s\n# FAIL: Throughput too low: 6808 writes/s\n# PASS: Slowest request took 0.228191s\n# PASS: Stddev is 0.033547s\n# FAIL\n```\n\n### CHECK DATASCALE [options]\n\nCHECK DATASCALE checks the memory usage of holding data for different workloads on a given server endpoint. Running the `check datascale` often can create a large keyspace history which can be auto compacted and defragmented using the `--auto-compact` and `--auto-defrag` options as described below.\n\nRPC: CheckDatascale\n\n#### Options\n\n- load -- the datascale check's workload model. Accepted workloads: s(small), m(medium), l(large), xl(xLarge)\n\n- prefix -- the prefix for writing the datascale check's keys.\n\n- auto-compact -- if true, compact storage with last revision after test is finished.\n\n- auto-defrag -- if true, defragment storage after test is finished.\n\n#### Output\n\nPrints the system memory usage for a given workload. Also prints status of compact and defragment if related options are passed.\n\n#### Examples\n\n```bash\n./etcdctl check datascale --load=\"s\" --auto-compact=true --auto-defrag=true\n# Start data scale check for work load [10000 key-value pairs, 1024 bytes per key-value, 50 concurrent clients].\n# Compacting with revision 18346204\n# Compacted with revision 18346204\n# Defragmenting \"127.0.0.1:2379\"\n# Defragmented \"127.0.0.1:2379\"\n# PASS: Approximate system memory used : 64.30 MB.\n```\n\n## Exit codes\n\nFor all commands, a successful execution return a zero exit code. All failures will return non-zero exit codes.\n\n## Output formats\n\nAll commands accept an output format by setting `-w` or `--write-out`. All commands default to the \"simple\" output format, which is meant to be human-readable. The simple format is listed in each command's `Output` description since it is customized for each command. If a command has a corresponding RPC, it will respect all output formats.\n\nIf a command fails, returning a non-zero exit code, an error string will be written to standard error regardless of output format.\n\n### Simple\n\nA format meant to be easy to parse and human-readable. Specific to each command.\n\n### JSON\n\nThe JSON encoding of the command's [RPC response][etcdrpc]. Since etcd's RPCs use byte strings, the JSON output will encode keys and values in base64.\n\nSome commands without an RPC also support JSON; see the command's `Output` description.\n\n### Protobuf\n\nThe protobuf encoding of the command's [RPC response][etcdrpc]. If an RPC is streaming, the stream messages will be concetenated. If an RPC is not given for a command, the protobuf output is not defined.\n\n### Fields\n\nAn output format similar to JSON but meant to parse with coreutils. For an integer field named `Field`, it writes a line in the format `\"Field\" : %d` where `%d` is go's integer formatting. For byte array fields, it writes `\"Field\" : %q` where `%q` is go's quoted string formatting (e.g., `[]byte{'a', '\\n'}` is written as `\"a\\n\"`).\n\n## Compatibility Support\n\netcdctl is still in its early stage. We try out best to ensure fully compatible releases, however we might break compatibility to fix bugs or improve commands. If we intend to release a version of etcdctl with backward incompatibilities, we will provide notice prior to release and have instructions on how to upgrade.\n\n### Input Compatibility\n\nInput includes the command name, its flags, and its arguments. We ensure backward compatibility of the input of normal commands in non-interactive mode.\n\n### Output Compatibility\n\nOutput includes output from etcdctl and its exit code. etcdctl provides `simple` output format by default.\nWe ensure compatibility for the `simple` output format of normal commands in non-interactive mode. Currently, we do not ensure\nbackward compatibility for `JSON` format and the format in non-interactive mode.

    "content": "etcdctl\n========\n\n`etcdctl` is a command line client for [etcd][etcd].\nIt can be used in scripts or for administrators to explore an etcd cluster.\n\n## Getting etcdctl\n\nThe latest release is available as a binary at [Github][github-release] along with etcd.\n\netcdctl can also be built from source using the build script found in the parent directory.\n\n## Configuration\n### --debug\n+ output cURL commands which can be used to reproduce the request\n\n### --no-sync\n+ don't synchronize cluster information before sending request\n+ Use this to access non-published client endpoints\n+ Without this flag, values from `--endpoint` flag will be overwritten by etcd cluster when it does internal sync.\n\n### --output, -o\n+ output response in the given format (`simple`, `extended` or `json`)\n+ default: `\"simple\"`\n\n### --discovery-srv, -D\n+ domain name to query for SRV records describing cluster endpoints\n+ default: none\n+ env variable: ETCDCTL_DISCOVERY_SRV\n\n### --peers\n+ a comma-delimited list of machine addresses in the cluster\n+ default: `\"http://127.0.0.1:2379\"`\n+ env variable: ETCDCTL_PEERS\n\n### --endpoint\n+ a comma-delimited list of machine addresses in the cluster\n+ default: `\"http://127.0.0.1:2379\"`\n+ env variable: ETCDCTL_ENDPOINT\n+ Without `--no-sync` flag, this will be overwritten by etcd cluster when it does internal sync.\n\n### --cert-file\n+ identify HTTPS client using this SSL certificate file\n+ default: none\n+ env variable: ETCDCTL_CERT_FILE\n\n### --key-file\n+ identify HTTPS client using this SSL key file\n+ default: none\n+ env variable: ETCDCTL_KEY_FILE\n\n### --ca-file\n+ verify certificates of HTTPS-enabled servers using this CA bundle\n+ default: none\n+ env variable: ETCDCTL_CA_FILE\n\n### --username, -u\n+ provide username[:password] and prompt if password is not supplied\n+ default: none\n+ env variable: ETCDCTL_USERNAME\n\n### --timeout\n+ connection timeout per request\n+ default: `\"1s\"`\n\n### --total-timeout\n+ timeout for the command execution (except watch)\n+ default: `\"5s\"`\n\n## Usage\n\n### Setting Key Values\n\nSet a value on the `/foo/bar` key:\n\n```sh\n$ etcdctl set /foo/bar \"Hello world\"\nHello world\n```\n\nSet a value on the `/foo/bar` key with a value that expires in 60 seconds:\n\n```sh\n$ etcdctl set /foo/bar \"Hello world\" --ttl 60\nHello world\n```\n\nConditionally set a value on `/foo/bar` if the previous value was \"Hello world\":\n\n```sh\n$ etcdctl set /foo/bar \"Goodbye world\" --swap-with-value \"Hello world\"\nGoodbye world\n```\n\nConditionally set a value on `/foo/bar` if the previous etcd index was 12:\n\n```sh\n$ etcdctl set /foo/bar \"Goodbye world\" --swap-with-index 12\nGoodbye world\n```\n\nCreate a new key `/foo/bar`, only if the key did not previously exist:\n\n```sh\n$ etcdctl mk /foo/new_bar \"Hello world\"\nHello world\n```\n\nCreate a new in-order key under dir `/fooDir`:\n\n```sh\n$ etcdctl mk --in-order /fooDir \"Hello world\"\n```\n\nCreate a new dir `/fooDir`, only if the key did not previously exist:\n\n```sh\n$ etcdctl mkdir /fooDir\n```\n\nUpdate an existing key `/foo/bar`, only if the key already existed:\n\n```sh\n$ etcdctl update /foo/bar \"Hola mundo\"\nHola mundo\n```\n\nCreate or update a directory called `/mydir`:\n\n```sh\n$ etcdctl setdir /mydir\n```\n\n\n### Retrieving a key value\n\nGet the current value for a single key in the local etcd node:\n\n```sh\n$ etcdctl get /foo/bar\nHello world\n```\n\nGet the value of a key with additional metadata in a parseable format:\n\n```sh\n$ etcdctl -o extended get /foo/bar\nKey: /foo/bar\nModified-Index: 72\nTTL: 0\nEtcd-Index: 72\nRaft-Index: 5611\nRaft-Term: 1\n\nHello World\n```\n\n### Listing a directory\n\nExplore the keyspace using the `ls` command\n\n```sh\n$ etcdctl ls\n/akey\n/adir\n$ etcdctl ls /adir\n/adir/key1\n/adir/key2\n```\n\nAdd `--recursive` to recursively list subdirectories encountered.\n\n```sh\n$ etcdctl ls --recursive\n/akey\n/adir\n/adir/key1\n/adir/key2\n```\n\nDirectories can also have a trailing `/` added to output using `-p`.\n\n```sh\n$ etcdctl ls -p\n/akey\n/adir/\n```\n\n### Deleting a key\n\nDelete a key:\n\n```sh\n$ etcdctl rm /foo/bar\n```\n\nDelete an empty directory or a key-value pair\n\n```sh\n$ etcdctl rmdir /path/to/dir\n```\n\nor\n\n```sh\n$ etcdctl rm /path/to/dir --dir\n```\n\nRecursively delete a key and all child keys:\n\n```sh\n$ etcdctl rm /path/to/dir --recursive\n```\n\nConditionally delete `/foo/bar` if the previous value was \"Hello world\":\n\n```sh\n$ etcdctl rm /foo/bar --with-value \"Hello world\"\n```\n\nConditionally delete `/foo/bar` if the previous etcd index was 12:\n\n```sh\n$ etcdctl rm /foo/bar --with-index 12\n```\n\n### Watching for changes\n\nWatch for only the next change on a key:\n\n```sh\n$ etcdctl watch /foo/bar\nHello world\n```\n\nContinuously watch a key:\n\n```sh\n$ etcdctl watch /foo/bar --forever\nHello world\n.... client hangs forever until ctrl+C printing values as key change\n```\n\nContinuously watch a key, starting with a given etcd index:\n\n```sh\n$ etcdctl watch /foo/bar --forever --index 12\nHello world\n.... client hangs forever until ctrl+C printing values as key change\n```\n\nContinuously watch a key and exec a program:\n\n```sh\n$ etcdctl exec-watch /foo/bar -- sh -c \"env | grep ETCD\"\nETCD_WATCH_ACTION=set\nETCD_WATCH_VALUE=My configuration stuff\nETCD_WATCH_MODIFIED_INDEX=1999\nETCD_WATCH_KEY=/foo/bar\nETCD_WATCH_ACTION=set\nETCD_WATCH_VALUE=My new configuration stuff\nETCD_WATCH_MODIFIED_INDEX=2000\nETCD_WATCH_KEY=/foo/bar\n```\n\nContinuously and recursively watch a key and exec a program:\n```sh\n$ etcdctl exec-watch --recursive /foo -- sh -c \"env | grep ETCD\"\nETCD_WATCH_ACTION=set\nETCD_WATCH_VALUE=My configuration stuff\nETCD_WATCH_MODIFIED_INDEX=1999\nETCD_WATCH_KEY=/foo/bar\nETCD_WATCH_ACTION=set\nETCD_WATCH_VALUE=My new configuration stuff\nETCD_WATCH_MODIFIED_INDEX=2000\nETCD_WATCH_KEY=/foo/barbar\n```\n\n## Return Codes\n\nThe following exit codes can be returned from etcdctl:\n\n```\n0    Success\n1    Malformed etcdctl arguments\n2    Failed to connect to host\n3    Failed to auth (client cert rejected, ca validation failure, etc)\n4    400 error from etcd\n5    500 error from etcd\n```\n\n## Endpoint\n\nIf the etcd cluster isn't available on `http://127.0.0.1:2379`, specify a `--endpoint` flag or `ETCDCTL_ENDPOINT` environment variable. One endpoint or a comma-separated list of endpoints can be listed. This option is ignored if the `--discovery-srv` option is provided.\n\n```sh\nETCDCTL_ENDPOINT=\"http://10.0.28.1:4002\" etcdctl set my-key to-a-value\nETCDCTL_ENDPOINT=\"http://10.0.28.1:4002,http://10.0.28.2:4002,http://10.0.28.3:4002\" etcdctl set my-key to-a-value\netcdctl --endpoint http://10.0.28.1:4002 my-key to-a-value\netcdctl --endpoint http://10.0.28.1:4002,http://10.0.28.2:4002,http://10.0.28.3:4002 etcdctl set my-key to-a-value\n```\n\n## Username and Password\n\nIf the etcd cluster is protected by [authentication][authentication], specify username and password using the [`--username`][username-flag] or `ETCDCTL_USERNAME` environment variable. When `--username` flag or `ETCDCTL_USERNAME` environment variable doesn't contain password, etcdctl will prompt password in interactive mode.\n\n```sh\nETCDCTL_USERNAME=\"root:password\" etcdctl set my-key to-a-value\n```\n\n## DNS Discovery\n\nTo discover the etcd cluster through domain SRV records,  specify a `--discovery-srv` flag or `ETCDCTL_DISCOVERY_SRV` environment variable. This option takes precedence over the `--endpoint` flag.\n\n```sh\nETCDCTL_DISCOVERY_SRV=\"some-domain\" etcdctl set my-key to-a-value\netcdctl --discovery-srv some-domain set my-key to-a-value\n```\n\n## Project Details\n\n### Versioning\n\netcdctl uses [semantic versioning][semver].\nReleases will follow lockstep with the etcd release cycle.\n\n### License\n\netcdctl is under the Apache 2.0 license.

    "content": "## Mirror Maker\n\nMirror maker mirrors a prefix in the key-value space of an etcd cluster into another prefix in another cluster. Mirroring is designed for copying configuration to various clusters distributed around the world. Mirroring usually has very low latency once it completes synchronizing with the initial state. Mirror maker utilizes the etcd watcher facility to immediately inform the mirror of any key modifications. Based on our experiments, the network latency between the mirror maker and the two clusters accounts for most of the latency. If the network is healthy, copying configuration held in etcd to the mirror should take under one second even for a world-wide deployment.\n\nIf the mirror maker fails to connect to one of the clusters, the mirroring will pause. Mirroring can  be resumed automatically once connectivity is reestablished.\n\nThe mirroring mechanism is unidirectional. Changing the value on the mirrored cluster won't reflect the value back to the origin cluster. The mirror maker only mirrors key-value pairs; metadata, such as version number or modification revision, is discarded. However, mirror maker still attempts to preserve update ordering during normal operation, but there is no ordering guarantee during initial sync nor during failure recovery following network interruption. As a rule of thumb, the ordering of the updates on the mirror should not be considered reliable.\n\n```\n+-------------+\n|             |\n|  source     |      +-----------+\n|  cluster    +----> |  mirror   |\n|             |      |  maker    |\n+-------------+      +---+-------+\n                         |\n                         v\n               +-------------+\n               |             |\n               |    mirror  |\n               |    cluster  |\n               |             |\n               +-------------+\n\n```\n\nMirror-maker is a built-in feature of [etcdctl][etcdctl].\n\n[etcdctl]: ../README.md\n"

    "content": "# etcdutl\n\n`etcdutl` is a command line administration utility for [etcd][etcd].\n\nIt's designed to operate directly on etcd data files.\nFor operations over a network, please use `etcdctl`.\n\n### DEFRAG [options]\n\nDEFRAG directly defragments an etcd data directory while etcd is not running.\nWhen an etcd member reclaims storage space from deleted and compacted keys, the space is kept in a free list and the database file remains the same size. By defragmenting the database, the etcd member releases this free space back to the file system.\n\nIn order to defrag a live etcd instances over the network, please use `etcdctl defrag` instead.\n\n#### Options\n\n- data-dir -- Optional. If present, defragments a data directory not in use by etcd.\n\n#### Output\n\nExit status '0' when the process was successful.\n\n#### Example\n\nTo defragment a data directory directly, use the `--data-dir` flag:\n\n``` bash\n# Defragment while etcd is not running\n./etcdutl defrag --data-dir default.etcd\n# success (exit status 0)\n# Error: cannot open database at default.etcd/member/snap/db\n```\n\n#### Remarks\n\nDEFRAG returns a zero exit code only if it succeeded in defragmenting all given endpoints.\n\n### SNAPSHOT RESTORE [options] \\<filename\\>\n\nSNAPSHOT RESTORE creates an etcd data directory for an etcd cluster member from a backend database snapshot and a new cluster configuration. Restoring the snapshot into each member for a new cluster configuration will initialize a new etcd cluster preloaded by the snapshot data.\n\n#### Options\n\nThe snapshot restore options closely resemble to those used in the `etcd` command for defining a cluster.\n\n- data-dir -- Path to the data directory. Uses \\<name\\>.etcd if none given.\n\n- wal-dir -- Path to the WAL directory. Uses data directory if none given.\n\n- initial-cluster -- The initial cluster configuration for the restored etcd cluster.\n\n- initial-cluster-token -- Initial cluster token for the restored etcd cluster.\n\n- initial-advertise-peer-urls -- List of peer URLs for the member being restored.\n\n- name -- Human-readable name for the etcd cluster member being restored.\n\n- skip-hash-check -- Ignore snapshot integrity hash value (required if copied from data directory)\n\n- bump-revision -- How much to increase the latest revision after restore\n\n- mark-compacted -- Mark the latest revision after restore as the point of scheduled compaction (required if --bump-revision > 0, disallowed otherwise)\n\n#### Output\n\nA new etcd data directory initialized with the snapshot.\n\n#### Example\n\nSave a snapshot, restore into a new 3 node cluster, and start the cluster:\n```\n# save snapshot\n./etcdctl snapshot save snapshot.db\n\n# restore members\n./etcdutl snapshot restore snapshot.db --initial-cluster-token etcd-cluster-1 --initial-advertise-peer-urls http://127.0.0.1:12380  --name sshot1 --initial-cluster 'sshot1=http://127.0.0.1:12380,sshot2=http://127.0.0.1:22380,sshot3=http://127.0.0.1:32380'\n./etcdutl snapshot restore snapshot.db --initial-cluster-token etcd-cluster-1 --initial-advertise-peer-urls http://127.0.0.1:22380  --name sshot2 --initial-cluster 'sshot1=http://127.0.0.1:12380,sshot2=http://127.0.0.1:22380,sshot3=http://127.0.0.1:32380'\n./etcdutl snapshot restore snapshot.db --initial-cluster-token etcd-cluster-1 --initial-advertise-peer-urls http://127.0.0.1:32380  --name sshot3 --initial-cluster 'sshot1=http://127.0.0.1:12380,sshot2=http://127.0.0.1:22380,sshot3=http://127.0.0.1:32380'\n\n# launch members\n./etcd --name sshot1 --listen-client-urls http://127.0.0.1:2379 --advertise-client-urls http://127.0.0.1:2379 --listen-peer-urls http://127.0.0.1:12380 &\n./etcd --name sshot2 --listen-client-urls http://127.0.0.1:22379 --advertise-client-urls http://127.0.0.1:22379 --listen-peer-urls http://127.0.0.1:22380 &\n./etcd --name sshot3 --listen-client-urls http://127.0.0.1:32379 --advertise-client-urls http://127.0.0.1:32379 --listen-peer-urls http://127.0.0.1:32380 &\n```\n\n### SNAPSHOT STATUS \\<filename\\>\n\nSNAPSHOT STATUS lists information about a given backend database snapshot file.\n\n#### Output\n\n##### Simple format\n\nPrints a humanized table of the database hash, revision, total keys, and size.\n\n##### JSON format\n\nPrints a line of JSON encoding the database hash, revision, total keys, and size.\n\n#### Examples\n```bash\n./etcdutl snapshot status file.db\n# cf1550fb, 3, 3, 25 kB\n```\n\n```bash\n./etcdutl --write-out=json snapshot status file.db\n# {\"hash\":3474280699,\"revision\":3,\"totalKey\":3,\"totalSize\":24576}\n```\n\n```bash\n./etcdutl --write-out=table snapshot status file.db\n+----------+----------+------------+------------+\n|   HASH   | REVISION | TOTAL KEYS | TOTAL SIZE |\n+----------+----------+------------+------------+\n| cf1550fb |        3 |          3 | 25 kB      |\n+----------+----------+------------+------------+\n```\n\n### HASHKV [options] \\<filename\\>\n\nHASHKV prints hash of keys and values up to given revision.\n\n#### Options\n\n- rev -- Revision number.

All failures will return non-zero exit codes.\n\n## Output formats\n\nAll commands accept an output format by setting `-w` or `--write-out`. All commands default to the \"simple\" output format, which is meant to be human-readable. The simple format is listed in each command's `Output` description since it is customized for each command. If a command has a corresponding RPC, it will respect all output formats.\n\nIf a command fails, returning a non-zero exit code, an error string will be written to standard error regardless of output format.\n\n### Simple\n\nA format meant to be easy to parse and human-readable. Specific to each command.\n\n### JSON\n\nThe JSON encoding of the command's [RPC response][etcdrpc]. Since etcd's RPCs use byte strings, the JSON output will encode keys and values in base64.\n\nSome commands without an RPC also support JSON; see the command's `Output` description.\n\n### Protobuf\n\nThe protobuf encoding of the command's [RPC response][etcdrpc]. If an RPC is streaming, the stream messages will be concatenated. If an RPC is not given for a command, the protobuf output is not defined.\n\n### Fields\n\nAn output format similar to JSON but meant to parse with coreutils. For an integer field named `Field`, it writes a line in the format `\"Field\" : %d` where `%d` is go's integer formatting. For byte array fields, it writes `\"Field\" : %q` where `%q` is go's quoted string formatting (e.g., `[]byte{'a', '\\n'}` is written as `\"a\\n\"`).\n\n## Compatibility Support\n\netcdutl is still in its early stage. We try out best to ensure fully compatible releases, however we might break compatibility to fix bugs or improve commands. If we intend to release a version of etcdutl with backward incompatibilities, we will provide notice prior to release and have instructions on how to upgrade.\n\n### Input Compatibility\n\nInput includes the command name, its flags, and its arguments. We ensure backward compatibility of the input of normal commands in non-interactive mode.\n\n### Output Compatibility\nCurrently, we do not ensure backward compatibility of utility commands.\n\n### TODO: compatibility with etcd server\n\n[etcd]: https://github.com/coreos/etcd\n[READMEv2]: READMEv2.md\n[v2key]: ../store/node_extern.go#L28-L37\n[v3key]: ../api/mvccpb/kv.proto#L12-L29\n[etcdrpc]: ../api/etcdserverpb/rpc.proto\n[storagerpc]: ../api/mvccpb/kv.proto\n"

All reports are thoroughly investigated by a dedicated committee of community volunteers called [Product Security Committee](security-release-process.md#product-security-committee).\n\nTo make a report, please email the private [security@etcd.io](mailto:security@etcd.io) list with the security details and the details expected for [all etcd bug reports](https://github.com/etcd-io/etcd/blob/main/Documentation/contributor-guide/reporting_bugs.md).\n\n### When Should I Report a Vulnerability?\n\n- When discovered a potential security vulnerability in etcd\n- When unsure how a vulnerability affects etcd\n- When discovered a vulnerability in another project that etcd depends on\n\n### When Should I NOT Report a Vulnerability?\n\n- Need help tuning etcd for security\n- Need help applying security related updates\n- When an issue is not security related\n\n## Security Vulnerability Response\n\nEach report is acknowledged and analyzed by Product Security Committee members within 3 working days. This will set off the [Security Release Process](security-release-process.md).\n\nAny vulnerability information shared with Product Security Committee stays within etcd project and will not be disseminated to other projects unless it is necessary to get the issue fixed.\n\nAs the security issue moves from triage, to identified fix, to release planning we will keep the reporter updated.\n\n## Public Disclosure Timing\n\nA public disclosure date is negotiated by the etcd Product Security Committee and the bug reporter. We prefer to fully disclose the bug as soon as possible once user mitigation is available. It is reasonable to delay disclosure when the bug or the fix is not yet fully understood, the solution is not well-tested, or for vendor coordination. The timeframe for disclosure is from immediate (especially if it's already publicly known) to a few weeks. As a basic default, we expect report date to disclosure date to be on the order of 7 days. The etcd Product Security Committee holds the final say when setting a disclosure date.\n\n## Security Audit\n\nA third party security audit was performed by Trail of Bits, find the full report [here](SECURITY_AUDIT.pdf).\nA third party fuzzing audit was performed by Ada Logics, find the full report [here](FUZZING_AUDIT_2022.PDF).\n\n"

The etcd community has adopted this security disclosures and response policy to ensure we responsibly handle critical issues.\n\n## Product Security Committee (PSC)\n\nSecurity vulnerabilities should be handled quickly and sometimes privately. The primary goal of this process is to reduce the total time users are vulnerable to publicly known exploits.\n\nThe PSC is responsible for organizing the entire response including internal communication and external disclosure but will need help from relevant developers and release leads to successfully run this process.\n\nThe PSC consists of the following:\n\n- Maintainers\n- Volunteer members as described in the [Product Security Committee Membership](#Product-Security-Committee-Membership)\n\nThe PSC members will share various tasks as listed below:\n\n- Triage: make sure the people who should be in \"the know\" (aka notified) are notified, also responds to issues that are not actually issues and let the etcd maintainers know that. This person is the escalation path for a bug if it is one. \n- Infra: make sure we can test the fixes appropriately.\n- Disclosure: handles public messaging around the bug. Documentation on how to upgrade. Changelog. Explaining to public the severity. notifications of bugs sent to mailing lists etc. Requests CVEs.\n- Release: Create new release addressing a security fix.\n\n### Contacting the Product Security Committee\n\nContact the team by sending email to [security@etcd.io](mailto:security@etcd.io).\n\n### Product Security Committee Membership\n\n#### Joining\n\nNew potential members to the PSC can express their interest to the PSC members. These individuals can be nominated by PSC members or etcd maintainers.\n\nIf representation changes due to job shifts then PSC members are encouraged to grow the team or replace themselves through mentoring new members.\n\n##### Product Security Committee Lazy Consensus Selection\n\nSelection of new members will be done by lazy consensus amongst members for adding new people with fallback on majority vote.\n\n#### Stepping Down\n\nMembers may step down at any time and propose a replacement from existing active contributors of etcd.\n\n#### Responsibilities\n\n- Members must remain active and responsive.\n- Members taking an extended leave of two weeks or more should coordinate with other members to ensure the role is adequately staffed during the leave.\n- Members going on leave for 1-3 months may identify a temporary replacement.\n- Members of a role should remove any other members that have not communicated a leave of absence and either cannot be reached for more than 1 month or are not fulfilling their documented responsibilities for more than 1 month. This may be done through a super-majority vote of members.\n\n## Disclosures\n\n### Private Disclosure Processes\n\nThe etcd Community asks that all suspected vulnerabilities be privately and responsibly disclosed as explained in the [README](README.md).\n\n### Public Disclosure Processes\n\nIf anyone knows of a publicly disclosed security vulnerability please IMMEDIATELY email [security@etcd.io](mailto:security@etcd.io) to inform the PSC about the vulnerability so they may start the patch, release, and communication process.\n\nIf possible the PSC will ask the person making the public report if the issue can be handled via a private disclosure process. If the reporter denies the PSC will move swiftly with the fix and release process. In extreme cases GitHub can be asked to delete the issue but this generally isn't necessary and is unlikely to make a public disclosure less damaging.\n\n## Patch, Release, and Public Communication\n\nFor each vulnerability, the PSC members will coordinate to create the fix and release, and sending email to the rest of the community. \n\nAll of the timelines below are suggestions and assume a Private Disclosure.\nThe PSC drives the schedule using their best judgment based on severity,\ndevelopment time, and release work. If the PSC is dealing with\na Public Disclosure all timelines become ASAP. If the fix relies on another\nupstream project's disclosure timeline, that will adjust the process as well.\nWe will work with the upstream project to fit their timeline and best protect\netcd users.\n\n### Fix Team Organization\n\nThese steps should be completed within the first 24 hours of Disclosure.\n\n- The PSC will work quickly to identify relevant engineers from the affected projects and packages and CC those engineers into the disclosure thread. These selected developers are the Fix Team. A best guess is to invite all maintainers.\n\n### Fix Development Process\n\nThese steps should be completed within the 1-7 days of Disclosure.\n\n- The PSC and the Fix Team will create a [CVSS](https://www.first.org/cvss/specification-document) using the [CVSS Calculator](https://www.first.org/cvss/calculator/3.0) to determine the effect and severity of the bug. The PSC makes the final call on the calculated risk; it is better to move quickly than make the perfect assessment.\n- The PSC will request a [CVE](https://cveform.mitre.org/).\n- The Fix Team will notify the PSC that work on the fix branch is complete once there are LGTMs on all commits from one or more maintainers.\n\nIf the CVSS score is under ~4.0\n([a low severity score](https://www.first.org/cvss/specification-document#i5)) or the assessed risk is low the Fix Team can decide to slow the release process down in the face of holidays, developer bandwidth, etc.\n\nNote: CVSS is convenient but imperfect. Ultimately, the PSC has discretion on classifying the severity of a vulnerability.\n\nThe severity of the bug and related handling decisions must be discussed on the [security@etcd.io](mailto:security@etcd.io) mailing list.\n\n### Fix Disclosure Process\n\nWith the Fix Development underway, the PSC needs to come up with an overall communication plan for the wider community. This Disclosure process should begin after the Fix Team has developed a Fix or mitigation so that a realistic timeline can be communicated to users.\n\n**Fix Release Day** (Completed within 1-21 days of Disclosure)\n\n- The PSC will cherry-pick the patches onto the main branch and all relevant release branches. The Fix Team will `lgtm` and `approve`.\n- The etcd maintainers will merge these PRs as quickly as possible.\n- The PSC will ensure all the binaries are built, publicly available, and functional.\n- The PSC will announce the new releases, the CVE number, severity, and impact, and the location of the binaries to get wide distribution and user action. As much as possible this announcement should be actionable, and include any mitigating steps users can take prior to upgrading to a fixed version. The recommended target time is 4pm UTC on a non-Friday weekday. This means the announcement will be seen morning Pacific, early evening Europe, and late evening Asia. The announcement will be sent via the following channels:\n  - etcd-dev@googlegroups.com\n  - [Kubernetes announcement slack channel](https://kubernetes.slack.com/messages/C9T0QMNG4)\n  - [sig-etcd slack channel](https://kubernetes.slack.com/archives/C3HD8ARJ5)\n\n## Retrospective\n\nThese steps should be completed 1-3 days after the Release Date. The retrospective process [should be blameless](https://landing.google.com/sre/book/chapters/postmortem-culture.html).\n\n- The PSC will send a retrospective of the process to etcd-dev@googlegroups.com including details on everyone involved, the timeline of the process, links to relevant PRs that introduced the issue, if relevant, and any critiques of the response and release process.\n- The PSC and Fix Team are also encouraged to send their own feedback on the process to etcd-dev@googlegroups.com. Honest critique is the only way we are going to get good at this as a community.\n"

Each\nrecord is 8-byte aligned so that the length field is never torn. The CRC contains the CRC32\nvalue of all record protobufs preceding the current record.\n\nWAL files are placed inside the directory in the following format:\n$seq-$index.wal\n\nThe first WAL file to be created will be 0000000000000000-0000000000000000.wal\nindicating an initial sequence of 0 and an initial raft index of 0. The first\nentry written to WAL MUST have raft index 0.\n\nWAL will cut its current tail wal file if its size exceeds 64 MB. This will increment an internal\nsequence number and cause a new file to be created. If the last raft index saved\nwas 0x20 and this is the first time cut has been called on this WAL then the sequence will\nincrement from 0x0 to 0x1. The new file will be: 0000000000000001-0000000000000021.wal.\nIf a second cut issues 0x10 entries with incremental index later, then the file will be called:\n0000000000000002-0000000000000031.wal.\n\nAt a later time a WAL can be opened at a particular snapshot. If there is no\nsnapshot, an empty snapshot should be passed in.\n\n\tindex := uint64(10)\n\tterm := uint64(2)\n\tw, err := wal.Open(\"/var/lib/etcd\", walpb.Snapshot{Index: &index, Term: &term})\n\t...\n\nThe snapshot must have been written to the WAL.\n\nAdditional items cannot be Saved to this WAL until all the items from the given\nsnapshot to the end of the WAL are read first:\n\n\tmetadata, state, ents, err := w.ReadAll()\n\nThis will give you the metadata, the last raft.State and the slice of\nraft.Entry items in the log.\n*/\npackage wal\n"

    "content": "# etcd Antithesis tests\n\nThis document describes the etcd test integration with [Antithesis].\nAntithesis provides a testing platform that allows you to explore edge cases, race conditions, and rare\nbugs that are difficult or impossible to reproduce in a normal environment.\n\n[Antithesis]: https://antithesis.com/\n\n## Robustness vs Antithesis tests\n\n[Antithesis] runs the robustness tests inside their\n[deterministic simulation testing](https://antithesis.com/resources/deterministic_simulation_testing/)\nenvironment and [fault injection](https://antithesis.com/docs/environment/fault_injection/).\n\nFor more details on robustness tests, see the [robustness directory](../robustness).\n\n## Antithesis Setup\n\nThe setup consists of a 3-node etcd cluster and a client container, orchestrated\nvia [Docker Compose](https://antithesis.com/docs/getting_started/setup/).\n\nDuring the etcd Antithesis test suite the etcd server is built with the following patches:\n\n* **Critical code locations**: We replace etcd `gofail` comments (which signify\n  code locations important for failure injection in robustness tests) with\n  Antithesis `assert.Reachable`. This guides Antithesis to explore the\n  execution space around these points.\n* **Assertions**: We change etcd `verify` package assertions to Antithesis\n  `assert.Always`, encouraging the platform to try and break those assertions.\n* **Instrumentation**: The etcd binary is instrumented using\n  `antithesis-go-instrumentor` to enable coverage tracking and feedback for\n  the Antithesis platform.\n\nThe Antithesis etcd tests configure the\n[Test Composer](https://antithesis.com/docs/test_templates/test_composer_reference/)\nin the following way:\n\n* **`entrypoint`**:\n  * Waits for all etcd nodes to be healthy.\n  * Emits the `setup_complete` message to Antithesis to start the testing phase.\n* **`singleton_driver_traffic`**:\n  * Generates robustness test traffic against the cluster while faults are injected.\n  * Runs as a [Singleton Driver Command], meaning it is the only one generating traffic.\n  * All generated traffic is saved as an operation history and stored on a shared volume.\n* **`finally_validation`**:\n  * Runs as a [Finally Command], meaning it is the last to run, with failure injection disabled.\n  * Reads the history of operations and validates them using the robustness test validation logic.\n  * Results of robustness tests are executed as Antithesis `assert.Always` assertions.\n  * Similar to robustness tests, it emits a visualization of the operations\n    history to an HTML file that is uploaded to the Antithesis platform.\n\n[Singleton Driver Command]: https://antithesis.com/docs/test_templates/test_composer_reference/#singleton-driver\n[Finally Command]: https://antithesis.com/docs/test_templates/test_composer_reference/#finally-command\n\n# Running tests with docker compose\n\n## Quickstart\n\n### 1. Build and Tag the Docker Image\n\nRun this command from the `antithesis/test-template` directory:\n\n```bash\nmake antithesis-build-client-docker-image\nmake antithesis-build-etcd-image\n```\n\nBoth commands build etcd-server and etcd-client from the current branch. To build a different version of etcd you can use:\n\n```bash\nmake antithesis-build-etcd-image REF=${GIT_REF} \n```\n\n### 2. (Optional) Check the Image Locally\n\nYou can verify your new image is built:\n\n```bash\ndocker images | grep etcd-client\n```\n\nIt should show something like:\n\n```\netcd-client        latest    <IMAGE_ID>    <DATE>\n```\n\n### 3. Use in Docker Compose\n\nRun the following command from the root directory for Antithesis tests (`tests/antithesis`):\n\n```bash\nmake antithesis-docker-compose-up\n```\n\nThe command uses the etcd client and server images built from step 1.\n\nThe client will continuously check the health of the etcd nodes and print logs similar to:\n\n```\n[+] Running 4/4\n ✔ Container etcd0   Created                                                                                                                                                 0.0s \n ✔ Container etcd2   Created                                                                                                                                                 0.0s \n ✔ Container etcd1   Created                                                                                                                                                 0.0s \n ✔ Container client  Recreated                                                                                                                                               0.1s \nAttaching to client, etcd0, etcd1, etcd2\netcd2   | {\"level\":\"info\",\"ts\":\"2025-04-14T07:23:25.134294Z\",\"caller\":\"flags/flag.go:113\",\"msg\":\"recognized and used environment variable\",\"variable-name\":\"ETCD_ADVERTISE_CLIENT_URLS\",\"variable-value\":\"http://etcd2.etcd:2379\"}\netcd2   | {\"level\":\"info\",\"ts\":\"2025-04-14T07:23:25.138501Z\",\"caller\":\"flags/flag.go:113\",\"msg\":\"recognized and used environment variable\",\"variable-name\":\"ETCD_INITIAL_ADVERTISE_PEER_URLS\",\"variable-value\":\"http://etcd2:2380\"}\netcd2   | {\"level\":\"info\",\"ts\":\"2025-04-14T07:23:25.138646Z\",\"caller\":\"flags/flag.go:113\",\"msg\":\"recognized and used environment variable\",\"variable-name\":\"ETCD_INITIAL_CLUSTER\",\"variable-value\":\"etcd0=http://etcd0:2380,etcd1=http://etcd1:2380,etcd2=http://etcd2:2380\"}\netcd0   | {\"level\":\"info\",\"ts\":\"2025-04-14T07:23:25.138434Z\",\"caller\":\"flags/flag.go:113\",\"msg\":\"recognized and used environment variable\",\"variable-name\":\"ETCD_ADVERTISE_CLIENT_URLS\",\"variable-value\":\"http://etcd0.etcd:2379\"}\netcd0   | {\"level\":\"info\",\"ts\":\"2025-04-14T07:23:25.138582Z\",\"caller\":\"flags/flag.go:113\",\"msg\":\"recognized and used environment variable\",\"variable-name\":\"ETCD_INITIAL_ADVERTISE_PEER_URLS\",\"variable-value\":\"http://etcd0:2380\"}\netcd0   | {\"level\":\"info\",\"ts\":\"2025-04-14T07:23:25.138592Z\",\"caller\":\"flags/flag.go:113\",\"msg\":\"recognized and used environment variable\",\"variable-name\":\"ETCD_INITIAL_CLUSTER\",\"variable-value\":\"etcd0=http://etcd0:2380,etcd1=http://etcd1:2380,etcd2=http://etcd2:2380\"}\n\n...\n...\n(skipping some repeated logs for brevity)\n...\n...\n\netcd2   | {\"level\":\"info\",\"ts\":\"2025-04-14T07:23:25.484698Z\",\"caller\":\"etcdmain/main.go:50\",\"msg\":\"successfully notified init daemon\"}\netcd1   | {\"level\":\"info\",\"ts\":\"2025-04-14T07:23:25.484092Z\",\"caller\":\"embed/serve.go:210\",\"msg\":\"serving client traffic insecurely; this is strongly discouraged!\",\"traffic\":\"grpc+http\",\"address\":\"[::]:2379\"}\netcd0   | {\"level\":\"info\",\"ts\":\"2025-04-14T07:23:25.484563Z\",\"caller\":\"etcdmain/main.go:50\",\"msg\":\"successfully notified init daemon\"}\netcd2   | {\"level\":\"info\",\"ts\":\"2025-04-14T07:23:25.485101Z\",\"caller\":\"v3rpc/health.go:61\",\"msg\":\"grpc service status changed\",\"service\":\"\",\"status\":\"SERVING\"}\netcd1   | {\"level\":\"info\",\"ts\":\"2025-04-14T07:23:25.484130Z\",\"caller\":\"etcdmain/main.go:44\",\"msg\":\"notifying init daemon\"}\netcd2   | {\"level\":\"info\",\"ts\":\"2025-04-14T07:23:25.485782Z\",\"caller\":\"embed/serve.go:210\",\"msg\":\"serving client traffic insecurely; this is strongly discouraged!\",\"traffic\":\"grpc+http\",\"address\":\"[::]:2379\"}\netcd1   | {\"level\":\"info\",\"ts\":\"2025-04-14T07:23:25.484198Z\",\"caller\":\"etcdmain/main.go:50\",\"msg\":\"successfully notified init daemon\"}\nclient  | Client [entrypoint]: starting...\nclient  | Client [entrypoint]: checking cluster health...\nclient  | Client [entrypoint]: connection successful with etcd0\nclient  | Client [entrypoint]: connection successful with etcd1\nclient  | Client [entrypoint]: connection successful with etcd2\nclient  | Client [entrypoint]: cluster is healthy!\n```\n\nAnd it will stay running indefinitely.\n\n### 4. Running the tests\n\n```bash\nmake antithesis-run-container-traffic\nmake antithesis-run-container-validation\n```\n\nAlternatively, with the etcd cluster from step 3, to run the tests locally without rebuilding the client image:\n\n```bash\nmake antithesis-run-local-traffic\nmake antithesis-run-local-validation\n```\n\n### 5. Prepare for next run\n\nUnfortunatelly robustness tests don't support running on non empty database.\nSo for now you need to cleanup the storage before repeating the run or you will get \"non empty database at start, required by model used for linearizability validation\" error.\n\n```bash\nmake antithesis-clean\n```\n\n## Troubleshooting\n\n- **Image Pull Errors**: If Docker can’t pull `etcd-client:latest`, make sure you built it locally (see the “Build and Tag” step) or push it to a registry that Compose can access.\n\n# Running Tests with Kubernetes (WIP)\n\n## Prerequisites\n\nPlease make sure that you have the following tools installed on your local:\n\n- [kubectl](https://kubernetes.io/docs/tasks/tools/#kubectl)\n- [kind](https://kind.sigs.k8s.io/docs/user/quick-start#installation)\n\n## Testing locally\n\n### Setting up the cluster and deploying the images\n\n#### 1. Ensure your access to a test kubernetes cluster\n\nYou can use `kind` to create a local cluster to deploy the etcd-server and test client.  Once you have `kind` installed, you can use the following command to create a local cluster:\n\n```bash\nkind create cluster\n```\n\nAlternatively, you can use any existing kubernetes cluster you have access to.\n\n#### 2. Build and load the images\n\nPlease [build the client and server images](#1-build-and-tag-the-docker-image) first. Then load the images into the `kind` cluster:\n\nIf you use `kind`, the cluster will need to have access to the images using the following commands:\n\n```bash\nkind load docker-image etcd-client:latest\nkind load docker-image etcd-server:latest\n```\n\nIf you use something other than `kind`, please make sure the images are accessible to your cluster. This might involve pushing the images to a container registry that your cluster can pull from.\n\n#### 3. Deploy the kubernetes manifests\n\n```bash\nkubectl apply -f ./config/manifests\n```\n\n### Tearing down the cluster\n\n```bash\nkind delete cluster --name kind\n```\n"

non-trivial changes to the robustness testing framework, it is critical to ensure that we do not lose the ability to reproduce previously discovered bugs. The track record table above documents known correctness issues, and many include specific reproduction commands (e.g., `make test-robustness-issue14370`).\n\nTo prevent regressions, we must ensure that the latest version of the robustness framework remains capable of reproducing old bugs.\nWe manually track this capability in the \"Last reproduction commit\" column.\n\n**Best Practices:**\n\n* **Establish Baseline:** Before starting a large non-trivial change, run all reproducible test cases listed in the track record table.\n* **Verify Reproducibility:** After completing the change, verify that all previously reproducible bugs can still be detected.\n* **Update Tracking:** Refresh the \"Last reproduction commit\" column with commit hash and it's creation date to confirm the new framework version works.\n* **Update Commands:** If the change affects test execution, update the reproduction commands accordingly.\n* **Gate Completion:** Consider the change incomplete until all regression tests continue to catch their target bugs.\n\nThis ensures that improvements to the testing framework do not inadvertently reduce our ability to detect known failure modes.\n\n## How Robustness Tests Work\n\nRobustness tests compare the etcd cluster behavior against a simplified model of its expected behavior.\nThese tests cover various scenarios, including:\n\n* **Different etcd cluster setups:** Cluster sizes, configurations, and deployment topologies.\n* **Client traffic types:**  Variety of key-value operations (puts, ranges, transactions) and watch patterns.\n* **Failures:** Network partitions, node crashes, disk failures, and other disruptions.\n\n**Test Procedure:**\n\n1. **Cluster Creation:**  A new etcd cluster is created with the specified configuration.\n2. **Traffic and Failures:** Client traffic is generated and sent to the cluster while failures are injected.\n3. **History Collection:** All client operations and their results are recorded.\n4. **Validation:** The collected history is validated against the etcd model and a set of validators to ensure consistency and correctness.\n5. **Report Generation:**  If a failure is detected then a detailed report is generated to help diagnose the issue.\n   This report includes information about the client operations and etcd data directories.\n\n## Key Concepts\n\n### Distributed System Terminology\n\n* **Consensus:** A process where nodes in a distributed system agree on a single data value. Etcd uses the Raft algorithm to achieve consensus.\n* **Strict vs Eventual consistency:**\n  * **Strict Consistency:** All components see the same data at the same time after an update.\n  * **Eventual Consistency:** Components may temporarily see different data after an update but converge to the same view eventually.\n* **Consistency Models (<https://jepsen.io/consistency>)**\n  * **Single-Object Consistency Models:**\n    * **Sequential Consistency:** A strong single-object model. Operations appear to take place in some total order, consistent with the order of operations on each individual process.\n    * **Linearizable Consistency:** The strongest single-object model. Operations appear to happen instantly and in order, consistent with real-time ordering.\n  * **Transactional Consistency Models**\n    * **Serializable Consistency:** A transactional model guaranteeing that transactions appear to occur in some total order. Operations within a transaction are atomic and do not interleave with other transactions. It's a multi-object property, applying to the entire system, not just individual objects.\n    * **Strict Serializable Consistency:** The strongest transactional model. Combines the total order of serializability with the real-time ordering constraints of linearizability.\n\nEtcd provides strict serializability for KV operations and eventual consistency for Watch.\n\n#### Etcd Guarantees\n\n* **Key-value API operations** <https://etcd.io/docs/latest/learning/api_guarantees/#kv-apis>\n* **Watch API guarantees** <https://etcd.io/docs/latest/learning/api_guarantees/#watch-apis>\n\n### Kubernetes Integration\n\n* **[Implicit Kubernetes-ETCD Contract]:**  Defines how Kubernetes uses etcd to store cluster state.\n* **ResourceVersion:**  A string used by Kubernetes to track resource versions, corresponding to etcd revisions.\n* **Sharding resource types:** Kubernetes treats each resource type as a totally independent entity.\n    It allows sharding each resource type into a separate etcd cluster.\n\n[Implicit Kubernetes-ETCD Contract]: https://docs.google.com/document/d/1NUZDiJeiIH5vo_FMaTWf0JtrQKCx0kpEaIIuPoj9P6A/edit?usp=sharing\n\n## Running locally\n\n1. Build etcd with failpoints\n\n    ```bash\n    make gofail-enable\n    make build\n    make gofail-disable\n    ```\n\n2. Run the tests\n\n    ```bash\n    make test-robustness\n    ```\n\n    Optionally, you can pass environment variables:\n    * `GO_TEST_FLAGS` - to pass additional arguments to `go test`.\n      It is recommended to run tests multiple times with failfast enabled. this can be done by setting `GO_TEST_FLAGS='--count=100 --failfast'`.\n    * `EXPECT_DEBUG=true` - to get logs from the cluster.\n    * `RESULTS_DIR` - to change the location where the results report will be saved.\n    * `PERSIST_RESULTS` - to persist the results report of the test. By default this will not be persisted in the case of a successful run.\n    * `TRACING_SERVER_ADDR` - to export Open Telemetry traces from test runs to the collector running at given address, for example: `localhost:4317`\n\n## Re-evaluate existing report\n\nRobustness test validation is constantly changing and improving.\nErrors in the etcd model could be causing false positives, which makes the ability to re-evaluate the reports after we fix the issue important.\n\n> Note: Robustness test report format is not stable, and it's expected that not all old reports can be re-evaluated using the newest version.\n\n1. Identify the location of the robustness test report.\n\n   > Note: By default robustness test report is only generated for failed test.\n\n   * **For local runs:** this would be by identifying log line, in the following example that would be `/tmp/TestRobustnessExploratory_Etcd_HighTraffic_ClusterOfSize1`:\n\n      ```text\n      logger.go:146: 2024-04-08T09:45:27.734+0200 INFO    Saving robustness test report   {\"path\": \"/tmp/TestRobustnessExploratory_Etcd_HighTraffic_ClusterOfSize1\"}\n      ```\n\n   * **For remote runs on CI:** you need to go to the [Prow Dashboard](https://testgrid.k8s.io/sig-etcd-robustness#Summary), go to a build, download one of the Artifacts (`artifacts/results.zip`), and extract it locally.\n\n     ![Prow job run page](readme-images/prow_job.png)\n\n     ![Prow job artifacts run page](readme-images/prow_job_artifacts_page.png)\n\n     ![Prow job artifacts run page artifacts dir](readme-images/prow_job_artifacts_dir_page.png)\n\n     Each directory will be prefixed by `TestRobustness` each containing a robustness test report.\n\n     ![artifact archive](readme-images/artifact_archive.png)\n\n     Pick one of the directories within the archive corresponding to the failed test scenario.\n     The largest directory by size usually corresponds to the failed scenario.\n     If you are not sure, you may check which scenario failed in the test logs.\n\n2. Copy the robustness report directory into the `testdata` directory.\n\n   The `testdata` directory can contain multiple robustness test reports.\n   The name of the report directory doesn't matter, as long as it's unique to prevent clashing with reports already present in `testdata` directory.\n   For example, the path for `history.html` file could look like `$REPO_ROOT/tests/robustness/testdata/v3.5_failure_24_April/history.html`.\n\n3. Run `make test-robustness-reports` to validate all reports in the `testdata` directory.\n\n## Analysing failure\n\nIf robustness tests fail, we want to analyse the report to confirm if the issue is on etcd side. The location of the directory with the report\nis mentioned in the `Saving robustness test report` log.

    "content": "## Overview\n\nGo tests in this directory analyze the usage of Etcd API based on collected\ntraces from a Kubernetes cluster. They output information on:\n\n1. Number of calls per gRPC method used by Kubernetes\n1. Key pattern\n1. Arguments provided to KV, Watch and Lease methods\n\nThis information can be used to track the coverage of k8s-etcd contract.\n\n### Manual test execution\n\nAt first we will manually set up the cluster, run e2e tests, download traces and\nthen execute the test.\n\n1. Customize and set the environment variables used by the code snippets below:\n\n```shell\n# Used for patches, building kind nodes, and running e2e tests.\nexport KUBERNETES_REPO=\"$(go env GOPATH)/src/k8s.io/kubernetes\"\n# Used when creating kind cluster and running e2e tests.\nexport KUBECONFIG=\"${KUBERNETES_REPO}/kind-with-tracing-config\"\n```\n\n1. Set up [KIND\ncluster](https://kind.sigs.k8s.io/docs/user/quick-start/#installation), exercise\nKubernetes API, export traces to [Jaeger](https://www.jaegertracing.io/) and\nthen download them:\n\n   ```shell\n   make k8s-coverage\n   ```\n\n1. Run Go test\n\n   ```shell\n   go test -v -timeout 60s go.etcd.io/etcd/tests/v3/robustness/coverage\n   ```\n\n1. Clean up the environment\n\n   ```shell\n   kind delete cluster --name kind-with-external-etcd\n   docker network rm kind-with-external-etcd\n   ```\n\n### Manual trace collection from robustness tests\n\n1. Run [Jaeger](https://www.jaegertracing.io/) container:\n\n   ```shell\n   docker run --rm --name jaeger \\\n     -p 16686:16686 \\\n     -p 4317:4317 \\\n     jaegertracing/jaeger:2.6.0 --set=extensions.jaeger_storage.backends.some_storage.memory.max_traces=20000000\n   ```\n\n1. Run robustness tests. For example:\n\n   ```shell\n   env \\\n     TRACING_SERVER_ADDR=localhost:4317 \\\n     GO_TEST_FLAGS='--timeout 10m --count=1 -v --run \"^TestRobustness.*/Kubernetes.*\"' \\\n     make test-robustness\n   ```\n\n1. Download traces and put them into `tests/robustness/coverage/testdata`\ndirectory in Etcd git repository:\n\n   ```shell\n   curl -v --get --retry 10 --retry-connrefused -o testdata/demo_traces.json \\\n     -H \"Content-Type: application/json\" \\\n     --data-urlencode \"query.start_time_min=$(date --date=\"5 days ago\" -Ins)\" \\\n     --data-urlencode \"query.start_time_max=$(date -Ins)\" \\\n     --data-urlencode \"query.service_name=etcd\" \\\n     \"http://localhost:16686/api/v3/traces\"\n   ```\n\n1. Run Go test\n\n   ```shell\n   go test -v -timeout 60s go.etcd.io/etcd/tests/v3/robustness/coverage\n   ```\n\n   It will show the coverage of Kubernetes-Etcd surface by robustness tests.:w\n\n### Automated test execution\n\nWork on improving these tests is tracked in\n[#20182](https://github.com/etcd-io/etcd/issues/20182) and periodic runs in\n[#20642](https://github.com/etcd-io/etcd/issues/20642).\n"

If $GOPATH environment variable is not set, the tool will be installed into the $HOME/go/bin. You can also find out the installed location by running the following command from the etcd source directory. Make sure that $PATH is set accordingly in your environment.\n\n```\n  $ go list -f \"{{.Target}}\" ./tools/etcd-dump-logs\n```\n\nAlternatively, instead of installing the tool, you can use it by simply running the following command from the etcd source directory.\n\n```\n  $ go run ./tools/etcd-dump-logs\n```\n\n## Usage\n\nThe following command should output the usage per the latest development.\n\n```\n  $ etcd-dump-logs --help\n```\n\nAn example of usage detail is provided below.\n\n```\nUsage:\n\n  etcd-dump-logs [data dir]\n    * Data dir is where the snapshots and WAL logs are located.

If $GOPATH environment variable is not set, the tool will be\ninstalled into the $HOME/go/bin. You can also find out the installed location by running the following command from the\netcd source directory. Make sure that $PATH is set accordingly in your environment.\n\n```\n  $ go list -f \"{{.Target}}\" ./tools/etcd-dump-metrics\n```\n\nAlternatively, instead of installing the tool, you can use it by simply running the following command from the etcd source\ndirectory.\n\n```\n  $ go run ./tools/etcd-dump-metrics\n```\n\n## Usage\n\nThe following command should output the usage per the latest development.\n\n```\n  $ etcd-dump-metrics --help\n```\n\nAn example of usage detail is provided below.\n\n### For the latest main branch\n```\n  $ etcd-dump-metrics\n```\n\n### For the provided endpoint\n```\n  $ goreman start\n  $ etcd-dump-metrics --addr http://localhost:2379/metrics\n```\n\n### Download specific version to temporary directory to fetch metrics\n```\n  $ etcd-dump-metrics --debug --download-ver v3.5.3\n  $ etcd-dump-metrics --download-ver v3.5.3\n```\n"

In a future etcd release this historic tool will be removed as it is no longer maintained.\n\nThe etcd local-tester runs a fault injected cluster using local processes.

A fault injection script periodically kills cluster members and disrupts bridge connectivity.\n\n# Requirements\n\nlocal-tester depends on `goreman` to manage its processes and `bash` to run fault injection.\n\n# Building\n\nlocal-tester needs `etcd`, `benchmark`, and `bridge` binaries.
