[jira] [Created] (SPARK-28738) Add ability to include metadata in CanCommitOffsets API

Joseph Cooper created SPARK-28738:
-------------------------------------

             Summary: Add ability to include metadata in CanCommitOffsets API
                 Key: SPARK-28738
                 URL: https://issues.apache.org/jira/browse/SPARK-28738
             Project: Spark
          Issue Type: New Feature
          Components: DStreams
    Affects Versions: 2.4.4
            Reporter: Joseph Cooper


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 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)].
