Andy Bryant commented on KAFKA-7051:
------------------------------------
We've seen this codeblock taking considerable CPU and time when profiling the
broker pushing data into a replicated topic where the cluster had a few
thousand partitions. Very keen to see this PR make 2.1.0
> Improve the efficiency of the ReplicaManager when there are many partitions
