+1 (non-binding) for this change. `DynamicMessage` is quite useful in
protobuf and support here would be great, I ran into a need for it just today.
cc @belugabehr in case they have thoughts. There aren't any active
protobuf-parquet committers AFAICT.

> 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
