Beam 2.29.0 Release

on GitHub

NOTE: This version was originally released on 2021-04-29 and added to GitHub releases late.

We are happy to present the new 2.29.0 release of Beam.
This release includes both improvements and new functionality.
See the download page for this release.

For more information on changes in 2.29.0, check out the detailed release notes.

Highlights

• Spark Classic and Portable runners officially support Spark 3 (BEAM-7093).
• Official Java 11 support for most runners (Dataflow, Flink, Spark) (BEAM-2530).
• DataFrame API now supports GroupBy.apply (BEAM-11628).

I/Os

• Added support for S3 filesystem on AWS SDK V2 (Java) (BEAM-7637)
• GCP BigQuery sink (file loads) uses runner determined sharding for unbounded data (BEAM-11772)
• KafkaIO now recognizes the partition property in writing records (BEAM-11806)
• Support for Hadoop configuration on ParquetIO (BEAM-11913)

New Features / Improvements

• DataFrame API now supports pandas 1.2.x (BEAM-11531).
• Multiple DataFrame API bugfixes (BEAM-12071, BEAM-11929)
• DDL supported in SQL transforms (BEAM-11850)
• Upgrade Flink runner to Flink version 1.12.2 (BEAM-11941)

Breaking Changes

• Deterministic coding enforced for GroupByKey and Stateful DoFns. Previously non-deterministic coding was allowed, resulting in keys not properly being grouped in some cases. (BEAM-11719)
  To restore the old behavior, one can register FakeDeterministicFastPrimitivesCoder with
  beam.coders.registry.register_fallback_coder(beam.coders.coders.FakeDeterministicFastPrimitivesCoder())
  or use the allow_non_deterministic_key_coders pipeline option.

Deprecations

• Support for Flink 1.8 and 1.9 will be removed in the next release (2.30.0) (BEAM-11948).

Known Issues

• See a full list of open issues that affect this version.
