Release notes

Implemented an input swap optimization for index joins.

Added a siren_dls query to be used by Investigate to segregate data.

Added support for enabled modules in Siren licenses.

Added a new REST endpoint for GQL queries /siren/_graph.

Upgraded to Elasticsearch 9.2.4.

Improved performance on Index Join strategy by using binary search to iterate over BytesRef.

Improved the can_match action to avoid serializing aggregations.

Improved the fingerprint and can_match actions to minimize the number of shards processed.

Added support for comma-separated indices in the join clause.

Removed the preference parameter for fingerprint computation.

Added ignore_query_cache query parameter to skip join query cache pruning strategy.

Improved the search-project task when the query is rewritten into a match_all.

Improved the initialization and cleanup job responsibilities.

Improved the concurrent execution of queries.

Removed unnecessary usage of the Guava EventBus.

Improved asynchronous execution in multi-search requests.

Added support for named join queries.

Changed to taskId for job identification instead of a random generated UUID.

Updated Calcite to version 1.40.0.

Improved project module dependencies.

Improved the license validation procedure.

Improved fingerprinting agnostic of DLS and FLS security system (i.e. XPack & SearchGuard).

Improved LogicalDataSignature hash computation to be deterministic and order agnostic.

Mutualize Query Shard Cache and Point-In-Time Shard Cache.

Fixed an issue in schema registration where collected futures could be incomplete when using multi-search.

Fixed a bug where the data segregation header was not included in the Elasticsearch request cache key, causing incorrect results when requests with different data segregation values hit the request cache.

Fixed query failures when using pre-indexed shape in Geoshape query and terms lookup parameters in Terms query within Federate join queries.

Fixed a thread context issue causing unintended cancellation of tasks triggered by other job completions.

Fixed a concurrency issue where multiple tasks could attempt to sort the same array during signature creation.

Fixed the federate_object runtime field data type when projecting multiple values.

Fixed unhandled CompletableFuture failures when the fingerprint encountered shard failures.

Fixed an error in calculating the hash of large queries in AQP requests.

Fixed a concurrent modification issue when creating task nodes.

Fixed an issue with dangling tasks in case of task cancellation failure.

Fixed a race condition when notifying task completion.

Fixed a validation rule in the static planner when joining on _index.

Fixed the took response time value to reflect the planner’s took_in_millis value.

Fixed request failures when shard allocation was disabled.

Fixed a race condition in the data upload queue.

Fixed a concurrent modification error when logging task metrics.

Fixed a missing entitlement entry for the json-ws processor.

Fixed missing planner times in AQP response, ensuring all timing metrics are now consistently reported.

Fixed an issue on KNN query parsing when using Federate joins.

Fixed projection clauses in /siren/_msearch requests.
