Description

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.
