Jun Rao created KAFKA-7299: ------------------------------ Summary: 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
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)
