Beam 2.52.0 release

on GitHub

We are happy to present the new 2.52.0 release of Beam.
This release includes both improvements and new functionality.
See the download page for this release.

For more information on changes in 2.52.0, check out the detailed release notes.

Highlights

• Previously deprecated Avro-dependent code (Beam Release 2.46.0) has been finally removed from Java SDK "core" package.
  Please, use beam-sdks-java-extensions-avro instead. This will allow to easily update Avro version in user code without
  potential breaking changes in Beam "core" since the Beam Avro extension already supports the latest Avro versions and
  should handle this. (#25252).
• Publishing Java 21 SDK container images now supported as part of Apache Beam release process. (#28120)
  • Direct Runner and Dataflow Runner support running pipelines on Java21 (experimental until tests fully setup). For other runners (Flink, Spark, Samza, etc) support status depend on runner projects.

New Features / Improvements

• Add UseDataStreamForBatch pipeline option to the Flink runner. When it is set to true, Flink runner will run batch
  jobs using the DataStream API. By default the option is set to false, so the batch jobs are still executed
  using the DataSet API.
• upload_graph as one of the Experiments options for DataflowRunner is no longer required when the graph is larger than 10MB for Java SDK (PR#28621.
• state amd side input cache has been enabled to a default of 100 MB. Use --max_cache_memory_usage_mb=X to provide cache size for the user state API and side inputs. (Python) (#28770).
• Beam YAML stable release. Beam pipelines can now be written using YAML and leverage the Beam YAML framework which includes a preliminary set of IO's and turnkey transforms. More information can be found in the YAML root folder and in the README.

Breaking Changes

• org.apache.beam.sdk.io.CountingSource.CounterMark uses custom CounterMarkCoder as a default coder since all Avro-dependent
  classes finally moved to extensions/avro. In case if it's still required to use AvroCoder for CounterMark, then,
  as a workaround, a copy of "old" CountingSource class should be placed into a project code and used directly
  (#25252).
• Renamed host to firestoreHost in FirestoreOptions to avoid potential conflict of command line arguments (Java) (#29201).

Bugfixes

• Fixed "Desired bundle size 0 bytes must be greater than 0" in Java SDK's BigtableIO.BigtableSource when you have more cores than bytes to read (Java) #28793.
• watch_file_pattern arg of the RunInference arg had no effect prior to 2.52.0. To use the behavior of arg watch_file_pattern prior to 2.52.0, follow the documentation at https://beam.apache.org/documentation/ml/side-input-updates/ and use WatchFilePattern PTransform as a SideInput. (#28948)
• MLTransform doesn't output artifacts such as min, max and quantiles. Instead, MLTransform will add a feature to output these artifacts as human readable format - #29017. For now, to use the artifacts such as min and max that were produced by the eariler MLTransform, use read_artifact_location of MLTransform, which reads artifacts that were produced earlier in a different MLTransform (#29016)
• Fixed a memory leak, which affected some long-running Python pipelines: #28246.

Security Fixes

• Fixed CVE-2023-39325 (Java/Python/Go) (#29118).
• Mitigated CVE-2023-47248 (Python) #29392.
