> Node restart causes unnecessary token metadata update
> -----------------------------------------------------

> Key: CASSANDRA-15133
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15133
> Project: Cassandra
> Issue Type: Improvement
> Components: Cluster/Gossip, Cluster/Membership
> Reporter: Jay Zhuang
> Assignee: Jay Zhuang
> Priority: Normal
>
> Restarting a node causes gossip generation update. When it propagates the
> message to the cluster, every node blindly update its local token metadata
> even it is not changed. Update token metadata is expensive for large vnode
> cluster and causes token metadata cache unnecessarily invalided.
