----------------------------------------
Summary: Controller should throttle partition reassignment
Key: KAFKA-10529
URL: https://issues.apache.org/jira/browse/KAFKA-10529
Project: Kafka
Issue Type: Improvement
Reporter: Badai Aqrandista
With
[KIP-455|[https://cwiki.apache.org/confluence/display/KAFKA/KIP-455%3A+Create+an+Administrative+API+for+Replica+Reassignment]],
reassignment can be triggered via AdminClient API. However, when reassigning a
large number of topic partitions at once, this can cause a storm of
LeaderAndIsr and UpdateMetadata requests, which can occupy Controller thread
for some time. And this prevents Controller from processing other requests.
So, Controller should throttle sending LeaderAndIsr request when actioning a
reassignment request.
