-------------------------------------
Hi [~gargsha] , I’ve been reproducing KAFKA-19652 (consumer throughput
regression in 3.9.0 vs 3.5.1, ZK mode) using the perf test tools. For accurate
benchmarking, should I fully load the topic first and then run the consumer, or
is it fine to run producer and consumer in parallel if I set
auto.offset.reset=earliest?
How is it usually done ?
