The Apache Beam SDK for Java provides a simple and elegant programming model to express your data processing pipelines; see the Apache Beam website for more information and getting started instructions.

The easiest way to use the Apache Beam SDK for Java is via one of the released artifacts from the Maven Central Repository.

Version numbers use the form major.minor.incremental and are incremented as follows:

Please note that APIs marked @Experimental may change at any point and are not guaranteed to remain compatible across versions.
