> There are multiple equivalent enums in the Beam Java SDK representing a compresison type:
> TextIO.CompressionType
> TFRecordIO.CompressionType
> XmlIO.CompressionType
> FileBasedSink.CompressionType
> CompressedSource.CompressionMode
> This is ugly and we should unify them. That is also necessary to enable authors of new file-based IOs to support compression without duplicating this functionality.
