Subject [jira] [Created] (KAFKA-5358) Consumer perf tool should count rebalance time separately
Date Thu, 01 Jun 2017 05:34:04 GMT
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.
