[jira] [Created] (BEAM-1891) Java @Autovalue: currently doesn't have a good coder

Stephen Sisk created BEAM-1891:
----------------------------------

             Summary: Java @Autovalue: currently doesn't have a good coder
                 Key: BEAM-1891
                 URL: https://issues.apache.org/jira/browse/BEAM-1891
             Project: Beam
          Issue Type: Improvement
          Components: sdk-java-extensions
            Reporter: Stephen Sisk
            Assignee: Davor Bonaci


In Java, @AutoValue classes are something that we would like developers to be able to use in PCollections in Beam.

However, there doesn't appear to be a good existing Beam Coder for Autovalue generated classes:
* Avrocoder doesn't work
* Serializable Coder works, but has other problems (larger/less efficient)
This is discussed fully at https://lists.apache.org/thread.html/29617096819824d5c12247a246d316b763d9e583a21fff2f1c430077@%3Cdev.beam.apache.org%3E 

We may need to implement an AutoValueCoder.
