Cherry pick KAFKA-19546 to 4.0. During online downgrade, when a static member using the consumer protocol which is also the last member using the consumer protocol is replaced by another static member using the classic protocol with the same instance id, the latter will take the assignment of the former and an online downgrade will be triggered. In the current implementation, if the replacing static member has a different subscription, no rebalance will be triggered when the downgrade happens. The patch checks whether the static member has changed subscription and triggers a rebalance when it does. Reviewers: Sean Quah <squah@confluent.io>, David Jacot <djacot@confluent.io> |
