KAFKA-4033: KIP-70: Revise Partition Assignment Semantics on New Consumer's Subscription Change This PR changes topic subscription semantics so a change in subscription does not immediately cause a rebalance. Instead, the next poll or the next scheduled metadata refresh will update the assigned partitions.
