[jira] [Created] (BEAM-2720) Exact-once Kafka sink

Raghu Angadi created BEAM-2720:
----------------------------------

             Summary: Exact-once Kafka sink
                 Key: BEAM-2720
                 URL: https://issues.apache.org/jira/browse/BEAM-2720
             Project: Beam
          Issue Type: New Feature
          Components: sdk-java-extensions
            Reporter: Raghu Angadi
            Assignee: Raghu Angadi


Kafka 0.11 added support for transactions which allows end-to-end exactly-once semantics. Beam's KafkaIO users can benefit from these while using runners that support exactly-once processing.

I have an implementation of EOS support for Kafka sink : https://github.com/apache/beam/pull/3612
It has two shuffles and builds on Beam state-API and checkpoint barrier between stages (as in Dataflow). Pull request has a longer description.
