Beam 2.23.0 release

We are happy to present the new 2.23.0 release of Apache Beam. This release includes both improvements and new functionality.
See the download page for this release.
For more information on changes in 2.23.0, check out the
detailed release notes.

Highlights

• Twister2 Runner (BEAM-7304).
• Python 3.8 support (BEAM-8494).

I/Os

• Support for reading from Snowflake added (Java) (BEAM-9722).
• Support for writing to Splunk added (Java) (BEAM-8596).
• Support for assume role added (Java) (BEAM-10335).
• A new transform to read from BigQuery has been added: apache_beam.io.gcp.bigquery.ReadFromBigQuery. This transform
  is experimental. It reads data from BigQuery by exporting data to Avro files, and reading those files. It also supports
  reading data by exporting to JSON files. This has small differences in behavior for Time and Date-related fields. See
  Pydoc for more information.
• Add dispositions for SnowflakeIO.write (BEAM-10343)

New Features / Improvements

• Update Snowflake JDBC dependency and add application=beam to connection URL (BEAM-10383).

Breaking Changes

• RowJson.RowJsonDeserializer, JsonToRow, and PubsubJsonTableProvider now accept "implicit
  nulls" by default when deserializing JSON (Java) (BEAM-10220).
  Previously nulls could only be represented with explicit null values, as in
  {"foo": "bar", "baz": null}, whereas an implicit null like {"foo": "bar"} would raise an
  exception. Now both JSON strings will yield the same result by default. This behavior can be
  overridden with RowJson.RowJsonDeserializer#withNullBehavior.
• Fixed a bug in GroupIntoBatches experimental transform in Python to actually group batches by key.
  This changes the output type for this transform (BEAM-6696).

Deprecations

• Remove Gearpump runner. (BEAM-9999)
• Remove Apex runner. (BEAM-9999)
• RedisIO.readAll() is deprecated and will be removed in 2 versions, users must use RedisIO.readKeyPatterns() as a replacement (BEAM-9747).

Beam 2.22.0 release

We are happy to present the new 2.22.0 release of Beam. This release includes both improvements and new functionality. See the download page for this release. For more information on changes in 2.22.0, check out the detailed release notes.

I/Os

• Basic Kafka read/write support for DataflowRunner (Python) (BEAM-8019).
• Sources and sinks for Google Healthcare APIs (Java)(BEAM-9468).

New Features / Improvements

• --workerCacheMB flag is supported in Dataflow streaming pipeline (BEAM-9964)
• --direct_num_workers=0 is supported for FnApi runner. It will set the number of threads/subprocesses to number of cores of the machine executing the pipeline (BEAM-9443).
• Python SDK now has experimental support for SqlTransform (BEAM-8603).
• Add OnWindowExpiration method to Stateful DoFn (BEAM-1589).
• Added PTransforms for Google Cloud DLP (Data Loss Prevention) services integration (BEAM-9723):
  • Inspection of data,
  • Deidentification of data,
  • Reidentification of data.
• Add a more complete I/O support matrix in the documentation site (BEAM-9916).
• Upgrade Sphinx to 3.0.3 for building PyDoc.
• Added a PTransform for image annotation using Google Cloud AI image processing service
  (BEAM-9646)

Breaking Changes

• The Python SDK now requires --job_endpoint to be set when using --runner=PortableRunner (BEAM-9860). Users seeking the old default behavior should set --runner=FlinkRunner instead.

Beam 2.21.0 release

We are happy to present the new 2.21.0 release of Beam. This release includes both improvements and new functionality.
See the download page for this release.
For more information on changes in 2.21.0, check out the
detailed release notes.

I/Os

• Python: Deprecated module apache_beam.io.gcp.datastore.v1 has been removed
  as the client it uses is out of date and does not support Python 3
  (BEAM-9529).
  Please migrate your code to use
  apache_beam.io.gcp.datastore.v1new.
  See the updated
  datastore_wordcount
  for example usage.
• Python SDK: Added integration tests and updated batch write functionality for Google Cloud Spanner transform (BEAM-8949).

New Features / Improvements

• Python SDK will now use Python 3 type annotations as pipeline type hints.
  (#10717)

  If you suspect that this feature is causing your pipeline to fail, calling
  apache_beam.typehints.disable_type_annotations() before pipeline creation
  will disable is completely, and decorating specific functions (such as
  process()) with @apache_beam.typehints.no_annotations will disable it
  for that function.

  More details will be in
  Ensuring Python Type Safety
  and an upcoming
  blog post.

• Java SDK: Introducing the concept of options in Beam Schema’s. These options add extra
  context to fields and schemas. This replaces the current Beam metadata that is present
  in a FieldType only, options are available in fields and row schemas. Schema options are
  fully typed and can contain complex rows. Remark: Schema aware is still experimental.
  (BEAM-9035)

• Java SDK: The protobuf extension is fully schema aware and also includes protobuf option
  conversion to beam schema options. Remark: Schema aware is still experimental.
  (BEAM-9044)

• Added ability to write to BigQuery via Avro file loads (Python) (BEAM-8841)

  By default, file loads will be done using JSON, but it is possible to
  specify the temp_file_format parameter to perform file exports with AVRO.
  AVRO-based file loads work by exporting Python types into Avro types, so
  to switch to Avro-based loads, you will need to change your data types
  from Json-compatible types (string-type dates and timestamp, long numeric
  values as strings) into Python native types that are written to Avro
  (Python's date, datetime types, decimal, etc). For more information
  see https://cloud.google.com/bigquery/docs/loading-data-cloud-storage-avro#avro_conversions.

• Added integration of Java SDK with Google Cloud AI VideoIntelligence service
  (BEAM-9147)

• Added integration of Java SDK with Google Cloud AI natural language processing API
  (BEAM-9634)

• docker-pull-licenses tag was introduced. Licenses/notices of third party dependencies will be added to the docker images when docker-pull-licenses was set.
  The files are added to /opt/apache/beam/third_party_licenses/.
  By default, no licenses/notices are added to the docker images. (BEAM-9136)

Breaking Changes

• Dataflow runner now requires the --region option to be set, unless a default value is set in the environment (BEAM-9199). See here for more details.
• HBaseIO.ReadAll now requires a PCollection of HBaseIO.Read objects instead of HBaseQuery objects (BEAM-9279).
• ProcessContext.updateWatermark has been removed in favor of using a WatermarkEstimator (BEAM-9430).
• Coder inference for PCollection of Row objects has been disabled (BEAM-9569).
• Go SDK docker images are no longer released until further notice.

Deprecations

• Java SDK: Beam Schema FieldType.getMetadata is now deprecated and is replaced by the Beam
  Schema Options, it will be removed in version 2.23.0. (BEAM-9704)
• The --zone option in the Dataflow runner is now deprecated. Please use --worker_zone instead. (BEAM-9716)
