> MirrorCheckpointTask uses OffsetSyncStore, and does not check whether OffsetSyncStore managed to read to the "end" of the offset-syncs topic. OffsetSyncStore should fetch the endoffset of the topic at startup, and set a flag when it finally reaches the endoffset in consumption. MirrorCheckpointTask.poll should wait for this flag to be true before doing any in-memory updates and group offset management.
