Ning Zhang created KAFKA-10339:
----------------------------------

             Summary: MirrorMaker2 Exactly-once Semantics
                 Key: KAFKA-10339
                 URL: https://issues.apache.org/jira/browse/KAFKA-10339
             Project: Kafka
          Issue Type: New Feature
          Components: KafkaConnect
            Reporter: Ning Zhang
            Assignee: Ning Zhang


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.
