----------------------------------
Summary: Enable clients to "re-bootstrap" in the event of a full
cluster migration
Key: KAFKA-4618
URL: https://issues.apache.org/jira/browse/KAFKA-4618
Project: Kafka
Issue Type: Improvement
Components: clients
Affects Versions: 0.10.1.1
Reporter: Dustin Cote
Priority: Minor
Today, clients only bootstrap upon startup. This works well in most cases, but
following up on the discussion
[here|https://issues.apache.org/jira/browse/KAFKA-3068?focusedCommentId=15115702&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15115702]
there are scenarios where you may want to "re-bootstrap" a client on the fly.
One example scenario is if you have an active-passive failover cluster setup
and a load balancer at the front managing. If you lose all of the brokers in
the active cluster and need to immediately failover to the other set of
brokers, you would need to re-bootstrap, meaning clients would have to restart.
Having the ability to go back through the bootstrapping process with a restart
would be a nice improvement.
