> 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.
