Kevin Lafferty commented on KAFKA-7299: --------------------------------------- [~junrao] can this be backported for inclusion in 1.1.2? > batch LeaderAndIsr requests during auto preferred leader election > ----------------------------------------------------------------- > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
