So this does not limit in any way, it just allows root transforms to be translated. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.

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. > CC [~robertwb] [~chamikara] [~thw] -- This message was sent by Atlassian JIRA (v7.6.3#76005)
