We are happy to present the new 2.34.0 release of Beam.
This release includes both improvements and new functionality.
See the download page for this release.

For more information on changes in 2.34.0, check out the detailed release
notes.

Highlights

  • The Beam Java API for Calcite SqlTransform is no longer experimental (BEAM-12680).
  • Python's ParDo (Map, FlatMap, etc.) transforms now suport a with_exception_handling option for easily ignoring bad records and implementing the dead letter pattern.

I/Os

  • ReadFromBigQuery and ReadAllFromBigQuery now run queries with BATCH priority by default. The query_priority parameter is introduced to the same transforms to allow configuring the query priority (Python) (BEAM-12913).
  • [EXPERIMENTAL] Support for BigQuery Storage Read API added to ReadFromBigQuery. The newly introduced method parameter can be set as DIRECT_READ to use the Storage Read API. The default is EXPORT which invokes a BigQuery export request. (Python) (BEAM-10917).
  • [EXPERIMENTAL] Added use_native_datetime parameter to ReadFromBigQuery to configure the return type of DATETIME fields when using ReadFromBigQuery. This parameter can only be used when method = DIRECT_READ(Python) (BEAM-10917).

New Features / Improvements

  • Upgrade to Calcite 1.26.0 (BEAM-9379).
  • Added a new dataframe extra to the Python SDK that tracks pandas versions
    we've verified compatibility with. We now recommend installing Beam with pip install apache-beam[dataframe] when you intend to use the DataFrame API
    (BEAM-12906).
  • Add an example of deploying Python Apache Beam job with Spark Cluster

Breaking Changes

  • SQL Rows are no longer flattened (BEAM-5505).
  • [Go SDK] beam.TryCrossLanguage's signature now matches beam.CrossLanguage. Like other Try functions it returns an error instead of panicking. (BEAM-9918).
  • BEAM-12925 was fixed. It used to silently pass incorrect null data read from JdbcIO. Pipelines affected by this will now start throwing failures instead of silently passing incorrect data.

Bugfixes

  • Fixed error while writing multiple DeferredFrames to csv (Python) (BEAM-12701).
  • Fixed error when importing the DataFrame API with pandas 1.0.x installed (BEAM-12945).
  • Fixed top.SmallestPerKey implementation in the Go SDK (BEAM-12946).
