We’re happy to announce today the release of Siren Federate version 33.0 for Elasticsearch version 7.17.15. This release includes the following improvements:

Improvements:

- Upgraded to Elasticsearch 7.17.15
- Added a circuit-breaker mechanism that makes multi-conditional joins fail fast if the `INDEX_JOIN` strategy needs to perform many index lookups that require a long processing time.
  - The maximum number of allowed lookups is controlled by a new dynamic setting `siren.planner.index_join.max_lookups`
  - The default value for this setting is 20,000.

- Updated the off-heap memory settings `siren.memory.{root,job,task}.limit` to be dynamic, facilitating the setup and configuration of Federate clusters.
- Added cache capabilities for AQP requests.
- Enabled Point-in-Time (PIT) for `inner join` requests.
- Added the `keep-alive` parameter for PIT requests.
- Introduced a resource manager for better handling of the resource life-cycle.
- Improved documentation with a table of operator compatibility for every data type.
- Improved documentation on joins with nested fields.

Deprecations:

- Deprecated the Ingestion API.
  - All requests under `/_siren/connector/ingestion` are marked as deprecated.
  - The following settings are also marked as deprecated:  
`siren.connector.ingestions.index`, `siren.connector.ingestion.bulk_size`, `siren.connector.ingestion.fetch_size`, `siren.connector.ingestion.index_timeout`,

- Deprecated the Job API.
  - All requests under `/_siren/connector/jobs` are marked as deprecated.

Bug fixes:

- Fixed an issue when the join query is not specified. A `match_all` query is used by default.
- Fixed a query cache miss when changing the order of conditions in a multi-conditional join request.
- Fixed an issue where the `X-Federate-Session-Id` header was set in lowercase.
- Fixed a race condition in the PIT request.
- Fixed a race condition when building reports in AQP requests.

Known issues:

- Opening a PIT for remote indices is not supported.
- Search slicing does not work with PIT.
