[jira] [Resolved] (KAFKA-8495) Make Round-robin / RangeAssignor to be "sticky" (part 5)

     [ https://issues.apache.org/jira/browse/KAFKA-8495?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sophie Blee-Goldman resolved KAFKA-8495.
----------------------------------------
    Resolution: Won't Do

Round-robin/range assignors will deliberately not support cooperative rebalancing, so no need to make them sticky

> 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.
