Ismael Juma created KAFKA-8788:
----------------------------------

             Summary: Optimize client metadata handling with a large number of partitions
                 Key: KAFKA-8788
                 URL: https://issues.apache.org/jira/browse/KAFKA-8788
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 2.3.0
            Reporter: Ismael Juma
            Assignee: Ismael Juma
             Fix For: 2.4.0, 2.3.1


Credit to [~lbradstreet] for profiling the producer with a large number of partitions.

There was a regression in 2.3.0 that made the client metadata handling significantly less efficient when dealing with a large number of partitions. There was a less significant regression in 2.2.0.

Lucas benchmarked the producer, but the code is shared with the consumer. See the PR for more details.
