[jira] [Created] (KAFKA-5358) Consumer perf tool should count
rebalance time separately
Jason Gustafson created KAFKA-5358:
--------------------------------------
Summary: Consumer perf tool should count rebalance time separately
Key: KAFKA-5358
URL: https://issues.apache.org/jira/browse/KAFKA-5358
Project: Kafka
Issue Type: Improvement
Reporter: Jason Gustafson
It would be helpful to measure rebalance time separately in the performance tool so that throughput between different versions can be compared more easily in spite of improvements such as https://cwiki.apache.org/confluence/display/KAFKA/KIP-134%3A+Delay+initial+consumer+group+rebalance. At the moment, running the perf tool on 0.11.0 or trunk for a short amount of time will present a severely skewed picture since the overall time will be dominated by the join group delay.
