Boyang Chen created KAFKA-7899: ---------------------------------- Summary: 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
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)
