Boyang Chen resolved KAFKA-7899. -------------------------------- Resolution: Invalid It appears that the metadata should be generated by the client instead of broker. So basically this is invalid issue. > Command line tool to invalidate group metadata for clean assignment > ------------------------------------------------------------------- > > Key: KAFKA-7899 > URL: https://issues.apache.org/jira/browse/KAFKA-7899 > Project: Kafka > Issue Type: New Feature > Components: consumer, streams > Affects Versions: 1.1.0 > Reporter: Boyang Chen > Assignee: Boyang Chen > Priority: Major > > Right now the group metadata will affect consumers under sticky assignment, > since it persists previous topic partition assignment which affects the > judgement of consumer leader. Specifically for KStream applications (under > 1.1), if we are scaling up the cluster, it is hard to balance the traffic > since most tasks would still go to "previous round active" assignments, even > though we hope them to move towards other hosts. > It would be preferable to have a tool to invalidate the group metadata stored > on broker, so that for sticky assignment we could have a clean start. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
