Onur Karaman created KAFKA-2017: ----------------------------------- Summary: Persist Coordinator State for Coordinator Failover Key: KAFKA-2017 URL: https://issues.apache.org/jira/browse/KAFKA-2017 Project: Kafka Issue Type: Sub-task Affects Versions: 0.9.0 Reporter: Onur Karaman Assignee: Onur Karaman
When a coordinator fails, the group membership protocol tries to failover to a new coordinator without forcing all the consumers rejoin their groups. This is possible if the coordinator persists its state so that the state can be transferred during coordinator failover. This state consists of most of the information in GroupRegistry and ConsumerRegistry. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
