Jack Vanlightly covers a common performance optimization:

Recently I was curious to see if there was any general performance improvement since Kafka 3.X. So I ran a suite of benchmarks with Dimster against 3.7.2 and 4.3.0. I saw two common patterns:

Those two patterns involved higher latency for the newer version of Kafka, but better scale. Click through to understand what changed between these two versions that had such a big impact.
