> PubSubIO: reimplement in Java
> -----------------------------
>
> Key: BEAM-53
> URL: https://issues.apache.org/jira/browse/BEAM-53
> Project: Beam
> Issue Type: New Feature
> Components: runner-core
> Reporter: Daniel Halperin
> Assignee: Mark Shields
>
> PubSubIO is currently only partially implemented in Java: the
> DirectPipelineRunner uses a non-scalable API in a single-threaded manner.
> In contrast, the DataflowPipelineRunner uses an entirely different code path
> implemented in the Google Cloud Dataflow service.
> We need to reimplement PubSubIO in Java in order to support other runners in
> a scalable way.
> Additionally, we can take this opportunity to add new features:
> * getting timestamp from an arbitrary lambda in arbitrary formats rather than
> from a message attribute in only 2 formats.
> * exposing metadata and attributes in the elements produced by PubSubIO.Read
> * setting metadata and attributes in the messages written by PubSubIO.Write
