------------------------------------------------------------
Yes; at least for AutoValue classes that a user has control over generating, this need is addressed by AutoValueSchema, introduced in https://github.com/apache/beam/pull/7334

> Project: Beam
> Issue Type: Improvement

> 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.
