             Summary: PubsubIO support for reading protos from schema
                 Key: BEAM-12297
                 URL: https://issues.apache.org/jira/browse/BEAM-12297
             Project: Beam
          Issue Type: New Feature
          Components: io-java-gcp
            Reporter: Zachary Houfek


We're trying to add a Dataflow template for Pubsub -> BigQuery where the Pubsub topic contains serialized proto data. This is similar to our existing template for Pubsub -> BigQuery using Avro.

However, it seems the PubsubIO currently only supports protos where the class is known.[1] We'll need something similar to the generic Avro reader[2].
