             Summary: Off by one error in generated snapshot IDs causes misaligned fetching
                 Key: KAFKA-14618
                 URL: https://issues.apache.org/jira/browse/KAFKA-14618
             Project: Kafka
          Issue Type: Bug
            Reporter: Jason Gustafson
            Assignee: Jason Gustafson
             Fix For: 3.4.0


We implemented new snapshot generation logic here: [https://github.com/apache/kafka/pull/12983.] A few days prior to this patch getting merged, we had changed the `RaftClient` API to pass the _exclusive_ offset when generating snapshots instead of the inclusive offset: [https://github.com/apache/kafka/pull/12981.] Unfortunately, the new snapshot generation logic was not updated accordingly. The consequence of this is that the state on replicas can get out of sync. In the best case, the followers fail replication because the offset after loading a snapshot is no longer aligned on a batch boundary.
