Those results stream out in real-time.</p>\n  </div>\n</div>\n\nYou interact with Quine by connecting it to a data source (Kafka, Kinesis Data Stream, SQS, files, stdin, etc.) and using regular database queries to stream that data in, build the graph structure, and find important patterns.\n\nThree design choices define Quine, setting it apart from all event stream processing systems:\n\n1. A graph-structured data model\n2. An asynchronous actor-based graph computational model\n3. Standing queries\n\nStanding queries live inside the graph and automatically propagate the incremental results computed from both historical data and new streaming data. Once matches are found, standing queries trigger actions using those results (e.g., execute code, transform other data in the graph, publish data to another system like Apache Kafka or Kinesis).\n\n![](https://uploads-ssl.webflow.com/61f0aecf55af2565526f6a95/62d8b7a7a13f0ca333a8b115_R9g-L0bLE2nguGQ3BRektSDq1d4L9Gtzao1fK3wuwgkX_iGkcgtGYlOR2u3p6DsWbrIrZbUPY6VtLULwj2BoIO2-gVUngIcrk-z-9H3u7a6QPIM7sqBRrkatR1YxA7WLR5CuvP3ZCo6JypuAWww23g.png)\n\nAll together, Quine can:\n\n* Consume high-volume streaming event data\n* Convert it into durable, versioned, connected data\n* Monitor that connected data for complex structures or values\n* Trigger arbitrary computation on the event of each match\n\nThis collection of capabilities is profoundly powerful! It represents a complete system for stateful event-driven arbitrary computation in a platform scalable to any size of data or desired throughput.\n\nRead the docs at [quine.io](https://quine.io) to learn more.  \n\n## Building from source\n\nIn order to build Quine locally, you'll need to have the following installed:\n\n  * A recent version of the Java Development Kit (17 or newer)\n  * The [`sbt` build tool](https://www.scala-sbt.org/download.html)\n  * Yarn 0.22.0+ (for frontend components of `quine-browser` subproject)\n\nThen:\n\n```\nsbt compile           # compile all projects\nsbt test              # compile and run all projects' tests\nsbt fixall            # reformat and lint all source files\nsbt quine/run         # to build and run Quine\nsbt quine/assembly    # assemble Quine into a jar \n```\n\n## Launch Quine:\n\nRun Quine from an executable `.jar` file built from this repo or downloaded from the repo [releases](https://github.com/thatdot/quine/releases) page. \n\n```shell\n❯ java -jar quine-x.x.x.jar -h\nQuine universal program\nUsage: quine [options]\n\n  -W, --disable-web-service\n                           disable Quine web service\n  -p, --port <value>       web service port (default is 8080)\n  -r, --recipe name, file, or URL\n                           follow the specified recipe\n  -x, --recipe-value key=value\n                           recipe parameter substitution\n  --force-config           disable recipe configuration defaults\n  --no-delete              disable deleting data file when process exits\n  -h, --help\n  -v, --version            print Quine program version\n```\n\nFor example, to run the [Wikipedia page ingest](https://quine.io/recipes/wikipedia/) getting started recipe:\n\n``` shell\n❯ java -jar quine-x.x.x.jar -r wikipedia\n ```\n\nWith Docker installed, run Quine from Docker Hub.\n\n``` shell\n❯ docker run -p 8080:8080 thatdot/quine\n```\n\nThe [quick start](https://quine.io/getting-started/quick-start/) guide will get you up and running the first time, ingesting data, and submitting your first query.\n\n## Quine Recipes\n\nQuine recipes are a great way to get started developing with Quine. A recipe is a document that contains all the information necessary for Quine to execute any data processing task. Ingest data from batch sources like `.json` or `.csv` files hosted locally, or connect to streaming data sources from Kafka or Kinesis. \n\n[Recipes](https://quine.io/components/recipe-ref-manual/) are `yaml` documents containing the configuration for components including:\n\n* [Ingest Streams](https://quine.io/components/ingest-sources/) to read streaming data from sources and update graph data\n* [Standing Queries](https://quine.io/components/standing-queries/) to transform graph data, and to produce aggregates and other outputs\n* UI configuration to specialize the web user interface for the use-case that is the subject of the Recipe\n\nPlease see [Quine's Recipe repository](https://quine.io/recipes/) for a list of available Recipes. Or create your own and contribute it back to the community for others to use.\n\n## Contributing to Quine\n\nThe community is the heart of all open-source projects. We welcome contributions from all people and strive to build a welcoming and open community of contributors, users, participants, speakers, and lurkers. Everyone is welcome.\n\nMore information is included in our [contribution](https://github.com/thatdot/quine/blob/main/CONTRIBUTING.md) guidelines.\n"

When that pattern is matched, with a\n  network SEND event, we have our smoking gun and a URL is logged linking to\n  the Quine Exploration UI with the full activity and context for investigation.\n  \n  In this scenario, a malicious Excel macro collects personal data and stores \n  it in a temporary file. The APT process \"ntclean\" infiltrated the system \n  previously through an SSH exploit, and now reads from that temporary file \n  and exfiltrates data from the network--hiding it as an HTTP GET request--\n  before deleting the temporary file to cover its tracks. \n\n  The source of the SSH exploit that planted the APT and the destination \n  for exfiltrated data utilize the same IP address.\n\n  SAMPLE DATA:\n    endpoint.json - https://recipes.quine.io/apt-detection/endpoint-json\n     network.json - https://recipes.quine.io/apt-detection/network-json\n\n  Download the sample data to the same directory where Quine will be run.\n\n  RESULTS:\n  When the standing query detects the WRITE->READ->SEND->DELETE pattern, it \n  will output a link to the console that can be copied and pasted into a \n  browser to explore the event in the Quine Exploration UI.\n\ningestStreams:\n  -

Thresholds are set to create\n  qualitative 'state' properties on each node indicating the health of the component\n  as 'good,' 'warn,' or 'alarm.'\n\n  Node appearance properties are set to add icons and colors to represent the type of\n  node and it's state, respectively, in the exploration UI.\n\n  Lastly, a standing query is defined to match consecutive cache misses within a\n  configurable fixed period of time for the purpose of alerting.\n\n  ------------------------------------------------------------------------------\n  Note 1\n  Sample data file for this recipe is in the file 'cdn_data_50k.json' which can\n  be accessed at https://that.re/cdn-data\n\n  Note 2\n  This recipe includes numerical thresholds for the hit/miss ratios in each node\n  creation ingest query. Change the thresholds as needed to provide the right color\n  indicators for your data!\ningestStreams:\n  - type: FileIngest\n    path: $in_file\n    format:\n      type: CypherJson\n      query:

The grid size, initial patterns, and \n  configuration are loaded from a JSON file specified at runtime.\n  \n  Each cell evaluates its neighbors and changes state only when Conway's rules dictate \n  a change, triggering cascading updates throughout the grid.\n  \n  Conway's Rules:\n  1. Live cell with 2-3 live neighbors survives\n  2. Dead cell with exactly 3 live neighbors becomes alive  \n  3. All other cells die or stay dead\n  \n  Usage: Specify JSON config file with --recipe-value config_file=path/to/config.json\n  The config file schema is as follows:\n  {\n    \"name\": \"My Game of Life\",\n    \"description\": \"A description of this setup\",\n    \"gridWidth\": 10,\n    \"gridHeight\": 10,\n    \"initialPattern\": [\n      {\"x\": 1, \"y\": 0, \"alive\": true},\n      {\"x\": 2, \"y\": 1, \"alive\": true},\n      {\"x\": 0, \"y\": 2, \"alive\": true},\n      {\"x\": 1, \"y\": 2, \"alive\": true},\n      {\"x\": 2, \"y\": 2, \"alive\": true}\n    ]\n  }\n\n  In Quine you can view all cell nodes with the following query: MATCH (c:Cell) RETURN c\n\n  Once Quine is running with this recipe, load the layout json from the UI to see the grid.\n  You can create a new layout by running the generate-conways-layout.js script while Quine is running.\n\n  Once the cell nodes are layed out, make sure to enable the bookmarklet.

Transactions are grouped by the block in which they were mined then imported\n  into the graph. Each wallet address is represented by a node, linked by an edge\n  to each transaction sent or received by that account, and linked by an edge to any\n  blocks mined by that account. Quick queries allow marking an account as \"tainted\".\n  The tainted flag is propagated along outgoing transaction paths via Standing Queries\n  to record the least degree of separation between a tainted source and an account\n  receiving a transaction. Canonical (eth-node-provided) capitalization is maintained where\n  possible, with `toLower` being used for idFrom-based ID resolution to reflect the\n  case-insensitive nature of bytestrings (eg addresses, hashes) used by Ethereum.\n\n  The Ethereum diamond logo is property of the Ethereum Foundation, used under the\n  terms of the Creative Commons Attribution 3.0 License.\niconImage: https://i.imgur.com/sSl6BQd.png\ningestStreams:\n  -

Further, the adjusted aggregates are used to alert on threshold \n  crossing (percentage of value of specific classes).\n\n  This is accomplished via three technical strategies:\n\n  1. Use of `NumberIteratorIngest` to generate sample transactions\n  2. Conditional handling of data\n  3.

Additionally, the persisted copy of these collections\n    * (ie those accessed by `*Metadata` functions) must be kept in sync with the in-memory copy. Because all of these\n    * functions are expected to have a low volume of usage, and thus don't need to be performance-optimized, we\n    * aggressively synchronize on locks. In particular, synchronizing on the collection itself is not sufficient, because\n    * the lock offered by `synchronize` is with respect to the locked *value*, not the locked *field* -- so locking on\n    * a mutating variable does not result in a mutex. By contrast, locking on a lock is more than is strictly necessary,\n    * but represents a deliberate choice to simplify the synchronization logic at the cost of reduced performance,\n    * as all these synchronization points should be low-volume.\n    *\n    * In the case of collections with only `get`/`set` functions, the @volatile annotation is sufficient to ensure the\n    * thread-safety of `get`. `set` functions must synchronize with a lock on `this` to ensure that setting both the\n    * in-memory and persisted copies of the collection happens at the same time.\n    *\n    * Get/set example:\n    * - `getQuickQueries` relies only on @volatile for its synchronization, because @volatile ensures all threads\n    * read the same state of the underlying `quickQueries` variable\n    * - `setQuickQueries` is wrapped in a `...Lock.synchronized` to ensure that 2 simultaneous calls to `setQuickQueries`\n    * will not interleave their local and remote update steps. Without synchronized, execution (1) might set the local\n    * variable while execution (2) sets the persisted version\n    *\n    * In the case of collections with update (eg `add`/`remove`) semantics, all accesses must be synchronized\n    * with a lock on `this`, because all accesses involve both a read and a write which might race concurrent executions.\n    *\n    * Add example:\n    * - `addIngestStream` is wrapped in a `...Lock.synchronized` because the updates it makes to `ingestStreams` depend on\n    * the results of a read of `ingestStreams`. Thus, the read and the write must happen atomically with respect to\n    * other `addIngestStream` invocations. Additionally, the `synchronized` ensures the local and persisted copies of\n    * the collection are kept in sync (as in the get/set case)\n    *\n    * Additionally, note that each synchronized{} block forces execution synchronization of futures it invokes (ie,\n    * each time a future is created, it is Await-ed). By Await-ing all futures created, we ensure that the\n    * synchronization boundary accounts for *all* work involved in the operation, not just the parts that happen on the\n    * local thread.

We then run\n\tan  ingest and a query for values containing that generated key. Each run therefore generates N new values in quine. The \n\tnumber of generated values is configurable but defaults to 10.\n\n## Limitations\n\t\n\t- Currently only testing Json ingest. \n\t- Only testing that ingest properly reads values into the Quine graph. Not testing things like stream offsets, throttling, optional parameters, ...\n \t\n\n\n"

The length of this list will vary based on\n      *         the graph structure, but will be no more than 1+length.\n      *\n      * This implementation is based on the Node2Vec procedure for random walk generation, which uses two parameters,\n      * \"p\" (the \"return\" parameter) and \"q\" (the \"in-out\" parameter).\n      * From the paper - https://cs.stanford.edu/~jure/pubs/node2vec-kdd16.pdf :\n      *\n      * *Return parameter*, p. Parameter p controls the likelihood of immediately revisiting a node in the walk.\n      * Setting it to a high value (> max(q, 1)) ensures that we are less likely to sample an already visited node\n      * in the following two steps (unless the next node in the walk had no other neighbor). This strategy encourages\n      * moderate exploration and avoids 2-hop redundancy in sampling. On the other hand, if p is low (< min(q, 1)),\n      * it would lead the walk to backtrack a step (Figure 2) and this would keep the walk \"local\" close to the\n      * starting node u.\n      *\n      * *In-out parameter*, q. Parameter q allows the search to differentiate between \"inward\" and \"outward\" nodes.\n      * Going back to Figure 2, if q > 1, the random walk is biased towards nodes close to node t. Such walks obtain\n      * a local view of the underlying graph with respect to the start node in the walk and approximate BFS behavior\n      * in the sense that our samples comprise of nodes within a small locality.\n      * In contrast, if q < 1, the walk is more inclined to visit nodes which are further away from the node t.\n      * Such behavior is reflective of DFS which encourages outward exploration. However, an essential difference\n      * here is that we achieve DFS-like exploration within the random walk framework. Hence, the sampled nodes are\n      * not at strictly increasing distances from a given source node u, but in turn, we benefit from tractable\n      * preprocessing and superior sampling efficiency of random walks. Note that by setting πv,x to be a function\n      * of the preceding node in the walk t, the random walks are 2nd order Markovian.\n      */\n    def randomWalk(\n      startingNode: QuineId,\n      collectQuery: CompiledQuery[Location.OnNode],\n      length: Int,\n      returnParam: Double,\n      inOutParam: Double,\n      walkSeqNum: Option[Int], // If none, you can manually prepend an integer to `seedOpt` to generate the same seed\n      seedOpt: Option[String],\n      namespace: NamespaceId,\n      atTime: Option[Milliseconds],\n    )(implicit\n      timeout: Timeout,\n    ): Future[RandomWalkResult] = relayAsk(\n      SpaceTimeQuineId(startingNode, namespace, atTime),\n      GetRandomWalk(\n        collectQuery,\n        length,\n        returnParam,\n        inOutParam,\n        walkSeqNum.fold(seedOpt)(num => seedOpt.map(s => s\"$num$s\")),\n        _,\n      ),\n    )\n\n    /** @param saveSink      An output sink which will handle receiving and writing each of the final walk results.\n      * @param collectQuery  A constrained OnNode Cypher query to fetch results to fold into the random walk results\n      * @param length        Number of steps to take through the graph.

integration layer for QueryStateBuilder.\n  * It takes a pure StateGraph and instantiates actual runtime states,\n  * managing their lifecycle and message routing.\n  *\n  * Separation of concerns:\n  *   - QueryStateBuilder: Pure logic to build StateGraph from QueryPlan\n  *   - QueryStateHost: Actor integration, lifecycle, message routing\n  *   - QueryState: Actual state machine implementations\n  *\n  * ==========================================================================\n  * STATE LIFECYCLE LIMITATIONS (Future Work Required)\n  * ==========================================================================\n  *\n  * Currently, QuinePattern states are NOT persisted. This creates several issues:\n  *\n  * 1. NODE SLEEP/WAKE STATE LOSS:\n  *    - When a node sleeps, its hostedStates are lost (in-memory only)\n  *    - On wake, there's no mechanism to restore states\n  *    - For AllNodes anchors: NodeWake fires but targetResults.contains(nodeId)\n  *      prevents re-dispatch since Anchor thinks it already dispatched\n  *    - For Computed anchors: No hook, state is lost permanently\n  *    - Result: Updates silently stop flowing from slept/woken nodes\n  *\n  * 2. STANDING QUERY UNREGISTRATION:\n  *    - Currently uses \"soft unregister\": just removes from local hostedStates\n  *    - Remote child states become orphaned (no UnregisterState sent to them)\n  *    - Orphaned states may continue sending updates to non-existent parents\n  *    - Updates to non-existent states are silently dropped (see routeNotification)\n  *\n  * 3. NODE HOOK MEMORY LEAK:\n  *    - AnchorState registers NodeWakeHooks but never unregisters them\n  *    - See cleanup() in AnchorState for details\n  *\n  * FUTURE VISION (similar to MultipleValuesStandingQuery):\n  *\n  * 1. State Persistence:\n  *    - Serialize states to persistor on install\n  *    - Restore states on node wake\n  *    - Enables proper state continuity across sleep/wake cycles\n  *\n  * 2. Standing Query Unregistration:\n  *    - Partial: Remove specific states while keeping query active\n  *    - Total: Remove entire standing query and all its states\n  *    - Challenge: Avoid waking entire subgraphs just for cleanup\n  *\n  * 3. Lazy Cleanup Strategy:\n  *    - Don't eagerly wake nodes to send UnregisterState\n  *    - Instead, have nodes validate on wake: \"is this state still relevant?\"\n  *    - Could use a global standing query registry for validation\n  *    - Orphaned states self-cleanup when they detect parent is gone\n  *\n  * 4. Epoch/Generation Tracking:\n  *    - Each standing query deployment has a generation number\n  *    - States check generation before publishing results\n  *    - Stale states (wrong generation) self-terminate\n  */\ntrait QueryStateHost { this: Actor =>\n\n  /** All hosted states indexed by their ID */\n  protected val hostedStates: mutable.Map[StandingQueryId, QueryState] =\n

EAGER CLEANUP WOULD WAKE SUBGRAPHS:\n    *    The current implementation sends UnregisterState to all target nodes via\n    *    graph.relayTell, which would wake sleeping nodes. For large standing queries\n    *    spanning many nodes, this could cause significant unnecessary node activation.\n    *\n    * FUTURE IMPLEMENTATION (see QueryStateHost trait docs):\n    *\n    * When we implement proper standing query lifecycle management:\n    *\n    * 1. Fix hook leak: Add graph.unregisterNodeHook(this) for AnchorState instances\n    *\n    * 2. Lazy cleanup for child states:\n    *    - Don't eagerly send UnregisterState to target nodes\n    *    - Instead, use a global standing query registry\n    *    - Nodes validate state relevance on wake via registry lookup\n    *    - Orphaned states self-cleanup when they detect parent query is gone\n    *\n    * 3. State persistence (like MVSQ):\n    *    - Persist states so they survive node sleep/wake\n    *    - On wake, restore states and validate against registry\n    *    - Enables proper incremental cleanup without waking entire subgraphs\n    *\n    * 4.

'''Annotation''': Each expression is assigned a type. Literals get concrete types\n  *    (Integer, Boolean, etc.), while unknowns get fresh TypeVariables.\n  *\n  * 2. '''Unification''': When two types must be equal (e.g., both sides of `=`),\n  *    `unify(t1, t2)` is called. This either:\n  *    - Succeeds silently if types are compatible\n  *    - Binds a TypeVariable to a concrete type in `typeEnv`\n  *    - Records a diagnostic if types are incompatible\n  *\n  * 3.

8MB, the shorter the\n   * better). This means that when we have maps with multiple keys, we need to encode those keys\n   * into a single `Array[Byte]`. Although RocksDB supports custom comparators implemented in Java\n   * (see `AbstractComparator`), these are much slower than the builtin comparators (since the\n   * native code must be calling back into JVM code _for each comparison_). The only builtin\n   * comparators are bytewise (equivalent to `java.util.Arrays.compareUnsigned([B,[B)`).\n   *\n   * All leads to the following conclusion: __our intuitive encoding of keys must be preserved as a\n   * bytewise ordering after being encoded__. In pseudo-code:\n   *\n   * {{{\n   * val key1: Key = ...\n   * val key2: Key = ...\n   * def encodeKey(k: Key): Array[Byte] = ...\n   *\n   * val directCompare: Int = key1 compare key2\n   * val encodedCompare: Int = java.util.Arrays.compareUnsigned(encodeKey(key1), encodeKey(key2))\n   * Integer.signum(directCompare) == Integer.signum(encodedCompare)\n   * }}}\n   *\n   * If the key to be encoded is a tuple of fixed-width types (UUID's, Long's, Int's, etc.) then it\n   * is enough to just concatenate their big-endian representations (modulo some small issues\n   * around signedness).
