> Hello. We would like to pass in a DynamicMessage rather than using the generated protobuf classes to allow us to make our job very generic.
> I think this could be achieved by setting the descriptor upfront, similarly to how there is a ProtoParquetOutputFormat today.
> In ProtoWriteSupport in the init method it could then generate the parquet schema created by ProtoSchemaConverter using the passed in descriptor, rather than taking it from the generated proto class.
> Would there be interest in incorporating this change? If so does the approach above sound sensible? I am happy to do a pull request
> initial PR here: https://github.com/apache/parquet-mr/pull/414
