Description

Make it easy to read and write binary files of Protobuf objects. If there is a standard open source format for this, use it.

If not, roll our own and implement it?

Imported from Jira BEAM-221. Original Jira may contain additional context. Reported by: dhalperi.

Contributor guide

Research direction
Investigate if Apache Beam already has a standard I/O connector for reading/writing Protobuf binary files. If not, design a solution by leveraging existing Beam I/O transforms (e.g., FileBasedSink, PCollection) and integrating with Protobuf serialization. Consider creating a custom I/O transform or contributing to Beam's DataflowRunner.
