Joseph Cooper updated SPARK-28738:
----------------------------------
Description:
It is possible to commit metadata with an offset to Kafka. Currently, the
CanCommitOffsets API does not expose this functionality. See
[https://github.com/apache/spark/blob/017919b636fd3ce43ccf5ec57f1c1842aa2130db/external/kafka-0-10/src/main/scala/org/apache/spark/streaming/kafka010/DirectKafkaInputDStream.scala#L300]
We could add a commitSync function which commits an offset right away and
accepts metadata.

We could make the commit queue take (OffsetRange, String) instead of just
OffsetRange and copy the two existing commitAsync functions and make them take
Array[(OffsetRange, String)].
