--------------------------------------
Summary: 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
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.
