Verifying Hashes and Signatures #

Maven Dependencies #

You can add the following dependencies to your pom.xml to include Apache Flink in your project. These dependencies include a local execution environment and thus support local testing.

  • Scala API: To use the Scala API, replace the flink-java artifact id with flink-scala_2.12 and flink-streaming-java with flink-streaming-scala_2.12.
<dependency>
  <groupId>org.apache.flink</groupId>
  <artifactId>flink-java</artifactId>
  <version>1.20.0</version>
</dependency>
<dependency>
  <groupId>org.apache.flink</groupId>
  <artifactId>flink-streaming-java</artifactId>
  <version>1.20.0</version>
</dependency>
<dependency>
  <groupId>org.apache.flink</groupId>
  <artifactId>flink-clients</artifactId>
  <version>1.20.0</version>
</dependency>

You can add the following dependencies to your pom.xml to include Apache Flink Stateful Functions in your project.

<dependency>
  <groupId>org.apache.flink</groupId>
  <artifactId>statefun-sdk</artifactId>
  <version>3.3.0</version>
</dependency>
<dependency>
  <groupId>org.apache.flink</groupId>
  <artifactId>statefun-flink-harness</artifactId>
  <version>3.3.0</version>
</dependency>

The statefun-sdk dependency is the only one you will need to start developing applications. The statefun-flink-harness dependency includes a local execution environment that allows you to locally test your application in an IDE.

You can add the following dependencies to your pom.xml to include Apache Flink ML in your project.

<dependency>
  <groupId>org.apache.flink</groupId>
  <artifactId>flink-ml-core</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>org.apache.flink</groupId>
  <artifactId>flink-ml-iteration</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>org.apache.flink</groupId>
  <artifactId>flink-ml-lib</artifactId>
  <version>2.3.0</version>
</dependency>

Advanced users could only import a minimal set of Flink ML dependencies for their target use-cases:

  • Use artifact flink-ml-core in order to develop custom ML algorithms.
  • Use artifacts flink-ml-core and flink-ml-iteration in order to develop custom ML algorithms which require iteration.
  • Use artifact flink-ml-lib in order to use the off-the-shelf ML algorithms from Flink ML.

You can add the following dependencies to your pom.xml to include Apache Flink Kubernetes Operator in your project.

<dependency>
  <groupId>org.apache.flink</groupId>
  <artifactId>flink-kubernetes-operator</artifactId>
  <version>1.10.0</version>
</dependency>

Update Policy for old releases #

As of March 2017, the Flink community decided to support the current and previous minor release with bugfixes. If 1.2.x is the current release, 1.1.y is the previous minor supported release. Both versions will receive bugfixes for critical issues.

As of March 2023, the Flink community decided that upon release of a new Flink minor version, the community will perform one final bugfix release for resolved critical/blocker issues in the Flink minor version losing support. If 1.16.1 is the current release and 1.15.4 is the latest previous patch version, once 1.17.0 is released we will create a 1.15.5 to flush out any resolved critical/blocker issues.

Note that the community is always open to discussing bugfix releases for even older versions. Please get in touch with the developers for that on the dev@flink.apache.org mailing list.
