We are happy to present the new 2.57.0 release of Beam.
This release includes both improvements and new functionality.
See the download page for this release.

For more information on changes in 2.57.0, check out the detailed release notes.

Highlights

  • Apache Beam adds Python 3.12 support (#29149).
  • Added FlinkRunner for Flink 1.18 (#30789).

I/Os

  • Ensure that BigtableIO closes the reader streams (#31477).

New Features / Improvements

  • Added Feast feature store handler for enrichment transform (Python) (#30957).
  • BigQuery per-worker metrics are reported by default for Streaming Dataflow Jobs (Java) (#31015)
  • Adds inMemory() variant of Java List and Map side inputs for more efficient lookups when the entire side input fits into memory.
  • Beam YAML now supports the jinja templating syntax.
    Template variables can be passed with the (json-formatted) --jinja_variables flag.
  • DataFrame API now supports pandas 2.1.x and adds 12 more string functions for Series.(#31185).
  • Added BigQuery handler for enrichment transform (Python) (#31295)
  • Disable soft delete policy when creating the default bucket for a project (Java) (#31324).
  • Added DoFn.SetupContextParam and DoFn.BundleContextParam which can be used
    as a python DoFn.process, Map, or FlatMap parameter to invoke a context
    manager per DoFn setup or bundle (analogous to using setup/teardown
    or start_bundle/finish_bundle respectively.)
  • Go SDK Prism Runner
    • Pre-built Prism binaries are now part of the release and are available via the Github release page. (#29697).
    • Some pipelines will work on Java and Python, but this is in part to prepare for real runner wrappers in 2.58.0
    • ProcessingTime is now handled synthetically with TestStream pipelines and Non-TestStream pipelines, for fast test pipeline execution by default. (#30083).
      • Prism does NOT yet support "real time" execution for this release.
  • Improve processing for large elements to reduce the chances for exceeding 2GB protobuf limits (Python)([https://github.com//issues/31607]).

Breaking Changes

  • Java's View.asList() side inputs are now optimized for iterating rather than
    indexing when in the global window.
    This new implementation still supports all (immutable) List methods as before,
    but some of the random access methods like get() and size() will be slower.
    To use the old implementation one can use View.asList().withRandomAccess().
  • SchemaTransforms implemented with TypedSchemaTransformProvider now produce a
    configuration Schema with snake_case naming convention
    (#31374). This will make the following
    cases problematic:
    • Running a pre-2.57.0 remote SDK pipeline containing a 2.57.0+ Java SchemaTransform,
      and vice versa:
    • Running a 2.57.0+ remote SDK pipeline containing a pre-2.57.0 Java SchemaTransform
    • All direct uses of Python's SchemaAwareExternalTransform
      should be updated to use new snake_case parameter names.
  • Upgraded Jackson Databind to 2.15.4 (Java) (#26743).
    jackson-2.15 has known breaking changes. An important one is it imposed a buffer limit for parser.
    If your custom PTransform/DoFn are affected, refer to #31580 for mitigation.
