Jay Kreps commented on KAFKA-562:
---------------------------------
Yeah, this is definitely a real problem that is leading to not all messages
being replicated. With the new logical offsets the followers should have
messages with offset 0, 1, 2, 3, 4... as the leader does. But instead the
followers have offsets 4,9,14,19,24... I.e. only every fifth message. Not sure
of the cause, looking into it.
