SDK Version Support Status

Warning: Dataflow SDK 1.x for Java is unsupported as of October 16, 2018. See Migrating from Dataflow SDK 1.x for Java for migration guidance.

SDK Decommission Notice: The following SDK versions will be decommissioned in late 2019 due to the discontinuation of support for JSON-RPC and Global HTTP Batch Endpoints.

• Apache Beam SDK for Java, versions 2.0.0 to 2.4.0 (inclusive)
• Apache Beam SDK for Python, versions 2.0.0 to 2.4.0 (inclusive)
• Dataflow SDK for Java, versions 2.0.0 to 2.4.0 (inclusive)
• Dataflow SDK for Python, 2.0.0 to 2.4.0 (inclusive)

Previously, the date planned for this decommissioning was March 25, 2019, but in response to customer requests, we are extending this timeline. The new end date has yet to be finalized but is expected to happen in 2019. When decommissioning happens, you will no longer be able to submit new Dataflow jobs or update running Dataflow jobs that use the decommissioned SDKs. In addition, existing streaming jobs that use these SDK versions may fail.

Dataflow SDK Deprecation Notice: The Dataflow SDK 2.5.0 is the last Dataflow SDK release that is separate from the Apache Beam SDK releases. The Dataflow service supports official Apache Beam SDK releases as documented in the SDK version support status page.

This page lists the support status for Apache Beam and Dataflow SDK releases:

• Apache Beam 2.x SDKs
• Cloud Dataflow 2.x SDKs
• Cloud Dataflow 1.x SDKs

In addition, existing streaming jobs that use these SDK versions may fail.

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.

However, the Apache Beam community designates specific releases as long term support (LTS) releases. LTS releases receive patches to fix major issues for a designated period of time. See the Apache Beam policies page for more details about release policies.

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:

2.10.0	Supported	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	This version will be deprecated on 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	Supported	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	This version will be deprecated on 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.
2.8.0	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 October 25, 2019. 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.

Dataflow 2.x SDKs

SDK Decommission Notice: The following SDK versions will be decommissioned in late 2019 due to the discontinuation of support for JSON-RPC and Global HTTP Batch Endpoints.

• Apache Beam SDK for Java, versions 2.0.0 to 2.4.0 (inclusive)
• Apache Beam SDK for Python, versions 2.0.0 to 2.4.0 (inclusive)
• Dataflow SDK for Java, versions 2.0.0 to 2.4.0 (inclusive)
• Dataflow SDK for Python, 2.0.0 to 2.4.0 (inclusive)

Previously, the date planned for this decommissioning was March 25, 2019, but in response to customer requests, we are extending this timeline. The new end date has yet to be finalized but is expected to happen in 2019. When decommissioning happens, you will no longer be able to submit new Dataflow jobs or update running Dataflow jobs that use the decommissioned SDKs. In addition, existing streaming jobs that use these SDK versions may fail.

Dataflow SDK Deprecation Notice: The Dataflow SDK 2.5.0 is the last Dataflow SDK release that is separate from the Apache Beam SDK releases. The Dataflow service supports official Apache Beam SDK releases as documented in the SDK version support status page.

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

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

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.
