Description
For this new algorithm to be effective in reducing rebalance costs, it is really expecting the plug-in assignor to be "sticky" in some way, such that the diff of the newly-assigned-partitions and the existing-assigned-partitions can be small, and hence only a few subset of the total number of partitions need to be revoked / migrated at each rebalance in practice – otherwise, we are just paying more rebalance for little benefits.
