[jira] [Commented] (KAFKA-12473) Make the "cooperative-sticky, range" as the default assignor

    [ https://issues.apache.org/jira/browse/KAFKA-12473?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17372219#comment-17372219 ] 

Konstantine Karantasis commented on KAFKA-12473:
------------------------------------------------

As [~showuon] suggested on the dev mailing list, I've moved this feature out of 3.0 and set its target to 3.1.0.

> Now that 3.0 is coming up, we can change the default ConsumerPartitionAssignor to something better than the RangeAssignor. The original plan was to switch over to the StickyAssignor, but now that we have incremental cooperative rebalancing we should  consider using the new CooperativeStickyAssignor instead: this will enable the consumer group to follow the COOPERATIVE protocol, improving the rebalancing experience OOTB.
