[jira] [Created] (CASSANDRA-15318) sendMessagesToNonlocalDC() should shuffle targets

Jon Meredith created CASSANDRA-15318:
----------------------------------------

             Summary: sendMessagesToNonlocalDC() should shuffle targets
                 Key: CASSANDRA-15318
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-15318
             Project: Cassandra
          Issue Type: Improvement
          Components: Messaging/Internode
            Reporter: Jon Meredith
            Assignee: Jon Meredith


To better spread load and reduce the impact of a node failure before detection (or other issues like issues host replacement), when forwarding messages to other data centers the forwarding non-local dc nodes should be selected at random rather than always selecting the first node in the list of endpoints for a token.
