Apache Druid 0.14.1-incubating is a small patch release that includes a handful of bug and documentation fixes from 16 contributors.

Important Notice

This release fixes an issue with druid-datasketches extension with quantile sketches, but introduces another one with theta sketches that was confirmed after the release was finalized, caused by #7320 and described in #7607. If you utilize theta sketches, we recommend not upgrading to this release. This will be fixed in the next release of Druid by #7619.

Bug Fixes

  • use latest sketches-core-0.13.1 #7320
  • Adjust BufferAggregator.get() impls to return copies #7464
  • DoublesSketchComplexMetricSerde: Handle empty strings. #7429
  • handle empty sketches #7526
  • Adds backwards-compatible serde for SeekableStreamStartSequenceNumbers. #7512
  • Support Kafka supervisor adopting running tasks between versions #7212
  • Fix time-extraction topN with non-STRING outputType. #7257
  • Fix two issues with Coordinator -> Overlord communication. #7412
  • refactor druid-bloom-filter aggregators #7496
  • Fix encoded taskId check in chatHandlerResource #7520
  • Fix too many dentry cache slab objs#7508. #7509
  • Fix result-level cache for queries #7325
  • Fix flattening Avro Maps with Utf8 keys #7258
  • Write null byte when indexing numeric dimensions with Hadoop #7020
  • Batch hadoop ingestion job doesn't work correctly with custom segments table #7492
  • Fix aggregatorFactory meta merge exception #7504

Documentation Changes

  • Fix broken link due to Typo. #7513
  • Some docs optimization #6890
  • Updated Javascript Affinity config docs #7441
  • fix expressions docs operator table #7420
  • Fix conflicting information in configuration doc #7299
  • Add missing doc link for operations/http-compression.html #7110

Updating from 0.14.0-incubating and earlier

Kafka Ingestion

Updating from version 0.13.0-incubating or earlier directly to 0.14.1-incubating will not require downtime like the migration path to 0.14.0-incubating due to the issue described in #6958, which has been fixed for this release in #7212. Likewise, rolling updates from version 0.13.0-incubating and earlier should also work properly due to #7512.

Native Parallel Ingestion

Updating from 0.13.0-incubating directly to 0.14.1-incubating will not encounter any issues during a rolling update with mixed versions of middle managers due to the fixes in #7520, as could be experienced when updating to 0.14.0-incubating.

Apache Druid (incubating) is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
