[jira] [Updated] (KAFKA-10794) Replica leader election is too slow
in the case of too many partitions
[ https://issues.apache.org/jira/browse/KAFKA-10794?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
limeng updated KAFKA-10794:
---------------------------
Description:
There is more than 6000 topics and 300 brokers in my kafka cluster, and we set the config:'auto.leader.rebalance.enable=true'.
The reblance process spendes too more time and cpu resource.
We find that the function:'controllerContext.allPartitions' is invoked too many times.
