Apache Beam is an open source, community-led project. Google is part of the community, but we do not own the project or control the release process. We might open bugs or submit patches to the Apache Beam codebase on behalf of Dataflow customers, but we cannot create hotfixes or official releases of Apache Beam on demand. See the Apache Beam policies page for more details about release policies.

Dataflow supports specific Apache Beam SDK components for the SDK releases listed below. These components have been tested thoroughly with Dataflow. Experimental features are not supported.

See the Apache Beam release notes for change information.

Note: Development SDK versions (marked as -SNAPSHOT for Java and .dev for Python) are unsupported.

The following tables contains the support status for the Apache Beam 2.x SDKs:

Known issues: The Dataflow runner has an incorrect logging configuration that might cause all logs to be missing. To work around this issue, add slf4j-jdk14 to your runtime dependencies.
2.11.0	Deprecated	org.apache.beam:beam-sdks-java-core org.apache.beam:beam-sdks-java-io-google-cloud-platform org.apache.beam:beam-sdks-java-extensions-google-cloud-platform-core org.apache.beam:beam-sdks-java-extensions-protobuf org.apache.beam:beam-runners-direct-java org.apache.beam:beam-runners-google-cloud-dataflow-java org.apache.beam:beam-model-pipeline org.apache.beam:beam-runners-core-construction-java org.apache.beam:beam-model-job-management org.apache.beam:beam-sdks-java-io-kafka	Deprecated as of March 1, 2020. Known issues: The Dataflow runner has an incorrect logging configuration that might cause all logs to be missing. To work around this issue, add slf4j-jdk14 to your runtime dependencies.
2.10.0	Deprecated	org.apache.beam:beam-sdks-java-core org.apache.beam:beam-sdks-java-io-google-cloud-platform org.apache.beam:beam-sdks-java-extensions-google-cloud-platform-core org.apache.beam:beam-sdks-java-extensions-protobuf org.apache.beam:beam-runners-direct-java org.apache.beam:beam-runners-google-cloud-dataflow-java org.apache.beam:beam-model-pipeline org.apache.beam:beam-runners-core-construction-java org.apache.beam:beam-model-job-management org.apache.beam:beam-sdks-java-io-kafka	Deprecated as of February 11, 2020. Known issues: SDK 2.10.0 depends on gcsio client library version 1.9.13, which has known issues: Reading side inputs can result in sending a large number of requests to Cloud Storage. As a result, Dataflow jobs can fail with HTTP 429 errors from Cloud Storage. Apache Beam ParquetIO fails when reading files from Cloud Storage. To work around these issues, either upgrade to SDK 2.11.0, or override the gcsio client library version to 1.9.16 or later. The Dataflow runner has an incorrect logging configuration that might cause all logs to be missing. To work around this issue, add slf4j-jdk14 to your runtime dependencies.
2.9.0	Deprecated	org.apache.beam:beam-sdks-java-core org.apache.beam:beam-sdks-java-io-google-cloud-platform org.apache.beam:beam-sdks-java-extensions-google-cloud-platform-core org.apache.beam:beam-sdks-java-extensions-protobuf org.apache.beam:beam-runners-direct-java org.apache.beam:beam-runners-google-cloud-dataflow-java org.apache.beam:beam-model-pipeline org.apache.beam:beam-runners-core-construction-java org.apache.beam:beam-model-job-management org.apache.beam:beam-sdks-java-io-kafka	Deprecated as of December 13, 2019. Known issues: Users enabling the Streaming Engine (Beta) experiment should not upgrade to SDK 2.9.0 due to a known issue. If you choose to use SDK 2.9.0, you must also set the enable_conscrypt_security_provider experimental flag to enable Conscrypt, which has known stability issues. In a specific case, users of Apache Beam Java SDKs 2.9.0 and earlier might experience data duplication when reading files from Cloud Storage. Duplication might occur when all of the following conditions are true: You are reading files with the content-encoding set to gzip, and the files are dynamically decompressive transcoded by Cloud Storage. The file size (decompressed) is larger than 2.14 GB. The input stream runs into an error (and is recreated) after 2.14 GB is read. As a workaround, do not set the content-encoding header, and store compressed files in Cloud Storage with the proper extension (for example, gz for gzip). For existing files, you can update the content-encoding header and file name with the gsutil tool.

Known issues: Pipelines might become stuck due to an issue with the Conscrypt library. If you see errors in Stackdriver logging with stack traces that include Conscrypt related calls, you might be affected by this issue. To resolve the issue, upgrade to SDK 2.9.0 or higher. In a specific case, users of Apache Beam Java SDKs 2.9.0 and earlier might experience data duplication when reading files from Cloud Storage. Duplication might occur when all of the following conditions are true: You are reading files with the content-encoding set to gzip, and the files are dynamically decompressive transcoded by Cloud Storage.

Duplication might occur when all of the following conditions are true: You are reading files with the content-encoding set to gzip, and the files are dynamically decompressive transcoded by Cloud Storage. The file size (decompressed) is larger than 2.14 GB. The input stream runs into an error (and is recreated) after 2.14 GB is read. As a workaround, do not set the content-encoding header, and store compressed files in Cloud Storage with the proper extension (for example, gz for gzip). For existing files, you can update the content-encoding header and file name with the gsutil tool.
