gaborgsomogyi commented on issue #24613: [SPARK-27549][SS] Add support for 
committing kafka offsets per batch for supporting external tooling
URL: https://github.com/apache/spark/pull/24613#issuecomment-493967858
 
 
   I've asked the high level question because if `KafkaOffsetReader` 
[fails](https://github.com/apache/spark/blob/974b8792205b2882f1b6c6f429c889dbf33434e6/external/kafka-0-10-sql/src/main/scala/org/apache/spark/sql/kafka010/KafkaOffsetReader.scala#L392)
 then a [new 
groupId](https://github.com/apache/spark/blob/974b8792205b2882f1b6c6f429c889dbf33434e6/external/kafka-0-10-sql/src/main/scala/org/apache/spark/sql/kafka010/KafkaOffsetReader.scala#L84)
 will be generated.
   
   In the case you've showed the following is possible:
   ```
   
[spark-kafka-source-413106f6-9d4f-491d-8782-f1f800acb6fe-1453634933-driver-0,TutorialTopic5,0]::OffsetAndMetadata(offset=0,
 leaderEpoch=Optional.empty, metadata=, commitTimestamp=1558354165044, 
expireTimestamp=None)
   
[spark-kafka-source-0b4ac39b-98d0-4e94-ae01-f4168bebae2a-1568478783-driver-1,TutorialTopic5,0]::OffsetAndMetadata(offset=0,
 leaderEpoch=Optional.empty, metadata=, commitTimestamp=1558354165044, 
expireTimestamp=None)
   
[spark-kafka-source-413106f6-9d4f-491d-8782-f1f800acb6fe-1453634933-driver-2,TutorialTopic5,0]::OffsetAndMetadata(offset=1,
 leaderEpoch=Optional.empty, metadata=, commitTimestamp=1558354170047, 
expireTimestamp=None)
   ...
   ```
   How are you planning to fetch the committed offsets from the tooling side?
