Ryanne Dolan commented on KAFKA-10339:
--------------------------------------
I believe your proposed task.loadOffsets() is taken care of by the existing
SinkTaskContext.offsets() method actually. This mechanism is used in other
SinkTasks where the offsets are stored in the downstream system. I think we may
already have all the interfaces required to make this work.

> MirrorMaker2 is currently implemented on Kafka Connect Framework, more
> specifically the Source Connector / Task, which do not provide exactly-once
> semantics (EOS) out-of-the-box, as discussed in
> https://github.com/confluentinc/kafka-connect-jdbc/issues/461,
> https://github.com/apache/kafka/pull/5553,
> https://issues.apache.org/jira/browse/KAFKA-6080 and
> https://issues.apache.org/jira/browse/KAFKA-3821. Therefore MirrorMaker2
> currently does not provide EOS.
