Description

Currently Kafka doesn't separate reassignment related replication from ISR replication. That is dangerous because if replication is throttled during reassignment and some replicas fall out of ISR they could get further behind while reassignment is also slower. We need a method that throttles reassignment related replication only.

A KIP is in progress for this.
