skonto edited a comment 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-492806050 @arunmahadevan I havent tried it but I know commits can be [out of order](https://books.google.gr/books?id=dXwzDwAAQBAJ&pg=PT100&lpg=PT100&dq=commitAsync+same+offsets&source=bl&ots=Y7Bq1G60iv&sig=ACfU3U39do_r-_aTWV-9uAT2t8eBXXbglQ&hl=el&sa=X&ved=2ahUKEwiMwcTno57iAhUiz6YKHXU9CgEQ6AEwEHoECAkQAQ#v=onepage&q=commitAsync%20same%20offsets&f=false), so I guess you can commit the same again. Needs verification. Btw I think this is a generic issue with the consumer what happens if your app crashes.
