>
> 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.
