> 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.
