> Key: KAFKA-14618
> URL: https://issues.apache.org/jira/browse/KAFKA-14618
> Project: Kafka
> Issue Type: Bug
> Reporter: Jason Gustafson
> Assignee: José Armando García Sancio
> Priority: Blocker
> 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.
