> I notice that we don't do a read-to-end of the offset syncs topic in MirrorCheckpointTask before we begin syncing consumer group offsets, and we begin reading that topic from the beginning. This may cause us to sync offsets based on stale checkpoints if there are later checkpoints available in the topic that we haven't consumed yet. Do you think it might make sense to add a read-to-end for the offset syncs topic before we begin syncing consumer group offsets in the checkpoint connector? Ouch, yeah that is certainly an issue that gets worse with my change. Before the checkpoints would be non-monotonic for transactional/compacted topics, and after it's non-monotonic for everyone. I think addressing this in a follow-up is a smart idea, this change is already messy enough. -- This is an automated message from the Apache Git Service.
