Subject [jira] [Created] (KAFKA-8682) Add meter for group rebalance rate
Date Thu, 18 Jul 2019 15:59:00 GMT
Jason Gustafson created KAFKA-8682:

             Summary: Add meter for group rebalance rate
                 Key: KAFKA-8682
                 URL: https://issues.apache.org/jira/browse/KAFKA-8682
             Project: Kafka
          Issue Type: Improvement
            Reporter: Jason Gustafson

The regression in KAFKA-8653 caused endless rebalances for consumers using older versions
of the JoinGroup protocol. Finding this problem was not easy because the consumer was still
making progress (albeit slowly). Eventually we found the problem by log inspection, but it
could have been detected sooner if we had a simple meter to monitor the rate of rebalances.
