Does the byte retention policy apply to replica partitions or leader partitions or both? In a multi-node cluster, with all brokers configured configured with different retention policies, it seems obvious that the partitions for which a given broker is a leader will be subject to the byte retention policy, but what about the partitions for which the given broker is a replica? Are they subject to the same policy?
For example, a 2 node cluster with single topic and two partitions. Broker A is the leader for partition 1 and contains the replica of partition 2 Broker B is the leader for partition 2 and contains the replica of partition 1 Broker A has a byte retention policy of 1 byte Broker B has a byte retention policy of 2 bytes Will broker A retain 1 byte of of both partitions it hosts? Likewise, will broker B retain 2 bytes of both partitions it hosts?
