Jun Rao commented on KAFKA-351:
-------------------------------
Another change in the patch:
M. Currently, on leaderAndISR request, the broker gets and creates all assigned
replicas. In this patch, the broker only creates replicas in ISR (since they
are required in the logic for shrinking ISR). Other remote replicas are created
on demand during the handling for follower fetch requests. This will make
implementing kafka-42 a bit easier since newly bootstrapped replicas can be
added on demand.
