[jira] [Commented] (CASSANDRA-2882) describe_ring should include
datacenter/topology information
[ https://issues.apache.org/jira/browse/CASSANDRA-2882?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13065496#comment-13065496 ]
Nate McCall commented on CASSANDRA-2882:
----------------------------------------
This should be considered related to CASSANDRA-1777
I think both of these are crucial to providing clients that can take advantage of topologies.

> describe_ring is great for getting a list of nodes in the cluster, but it doesn't provide any information about the network topology which prevents it's use in a multi-dc setup. It would be nice if we added another list to the TokenRange object containing the DC information.
> Optimally I could have ask any Cassandra node for this information and on the client-side prefer local nodes but be able to fail to remote nodes without requiring another lookup.
