Ben Stopford updated KAFKA-4216:
--------------------------------
Summary: Replication Quotas: Control Leader & Follower Throttled Replicas
Separately (was: Replication Throttling: Leader may not be throttled if it is
not "moving")
> Replication Quotas: Control Leader & Follower Throttled Replicas Separately
> ---------------------------------------------------------------------------
>
> Key: KAFKA-4216
> URL: https://issues.apache.org/jira/browse/KAFKA-4216
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.10.1.0
> Reporter: Ben Stopford
> Assignee: Ben Stopford
>
> The current algorithm in kafka-reassign-partitions applies a throttle to all
> moving replicas, be they leader-side or follower-side.
> A preferable solution would be to change the throttled replica list to
> specify whether the throttle applies to leader or follower. That way we can
> ensure that the regular replication will not be throttled.
> To do this we should change the way the throttled replica list is specified
> so it is spread over two separate properties. One that corresponds to the
> leader-side throttle, and the other that corresponds to the follower-side
> throttle.
> quota.leader.replication.throttled.replicas =
> [partId]:[replica],[partId]:[replica],[partId]:[replica]
> quota.follower.replication.throttled.replicas =
> [partId]:[replica],[partId]:[replica],[partId]:[replica]
> Then, when applying the throttle, the leader quota can be applied to all
> current replicas, and the follower quota can be applied only to the new
> replicas we are creating as part of the rebalance.
