----------------------------------
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.
