Subject [jira] [Commented] (CASSANDRA-2882) describe_ring should include datacenter/topology information
Date Thu, 14 Jul 2011 19:46:00 GMT

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.
