-------------------------------------------
Thanks Stephen, Yes I was looking for that.
> 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
> Priority: Minor
> Labels: newbie, starter
>
> 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.
