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.
