> Key: KAFKA-7299
> URL: https://issues.apache.org/jira/browse/KAFKA-7299
> Project: Kafka
> Issue Type: Sub-task
> Components: core
> Affects Versions: 2.0.0
> Reporter: Jun Rao
> Assignee: huxihx
> Priority: Major
> Fix For: 2.1.0
>
>
> Currently, in KafkaController.checkAndTriggerAutoLeaderRebalance(), we call
> onPreferredReplicaElection() one partition at a time. This means that the
> controller will be sending LeaderAndIsrRequest one partition at a time. It
> would be more efficient to call onPreferredReplicaElection() for a batch of
> partitions to reduce the number of LeaderAndIsrRequests.
