Review comment:
This limit cross language pipelines to sources only. Shall we keep them
general?

> Expose Java transforms (specifically IO) in other SDKs
> ------------------------------------------------------
>
> Key: BEAM-6730
> URL: https://issues.apache.org/jira/browse/BEAM-6730
> Project: Beam
> Issue Type: New Feature
> Components: runner-flink, sdk-java-core, sdk-py-core
> Reporter: Maximilian Michels
> Assignee: Maximilian Michels
> Priority: Major
> Time Spent: 3.5h
> Remaining Estimate: 0h
>
> Since https://github.com/apache/beam/pull/7316 we can reference external
> transforms which are transforms only available in a "foreign" SDKs. This
> allows us to fill the gap in terms of missing transforms in the Python and Go
> SDK, specifically IO transforms.
> We can start collecting/exposing transforms that Beam users need. The
> following transforms could be interesting:
> - KafkaIO / KinesisIO
> - CassandraIO / ElasticserchIO / Hbase / Redis
> - JDBC
> - S3 file system
> - GenerateSequence
> See also https://s.apache.org/beam-cross-language-io and BEAM-6485.
