--------------------------------------
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.
