Hi Martin,
Code for reconnecting after rollback has been tested and committed to the kafka-connect-couchbase GitHub repo, and will ship in the 3.2.2 release scheduled for July 17th.
If you’d like to verify the fix works in your environment, I’d recommend building the connector from source (or if that’s a hassle, ping me and we’ll get you a pre-built snapshot). Then if you run into any issues, we’ll have a chance to address then ahead of the official release.
Thanks,
David
