[jira] [Created] (CASSANDRA-15133) Node restart causes unnecessary token metadata update

Jay Zhuang created CASSANDRA-15133:
--------------------------------------

             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.
