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 should include datacenter/topology information

> Key: CASSANDRA-2882
> URL: https://issues.apache.org/jira/browse/CASSANDRA-2882
> Project: Cassandra
> Issue Type: Improvement
> Components: API, Core
> Reporter: Mark Guzman
> Priority: Minor
>
> 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.
