Description

Parquet infrastructure does support writing protobuf data to parquet. Beam's ParquetIO could give pipeline developers an option to write protobuf data instead of converting them to avro.

Imported from Jira BEAM-6394. Original Jira may contain additional context. Reported by: JozoVilcek.

Contributor guide

Research direction
Examine the existing ParquetIO classes for writing Avro, and create a similar implementation for Protobuf using ProtobufUtil or custom WriteSupport.
