Yup, this looks like pretty good coverage of the topic. I *think* I like the idea of Cassandra pushing a CF change to its peers, as opposed to managing it by a separate admin task, simply because I wouldn't want a change managed by an application admin to be missed because of bad communication, forgetfulness, etc., with the Ops team.
So, considering that I currently have to take down a node to make a CF change, I'm wondering how to perform automatic failover from my application? Is there a mechanism by which I can request from Cassandra all the destination IP:ports for the nodes in a cluster, so I can adapt dynamically? For example, if I ramp up/down Cassandra instances based on server load, I would like my application to automatically know what servers are available, to execute automatic reconnection when the node I'm connected to goes down.

Well, it's sort of the same thing, in that you need the latter and the former is the simplest way to actually interface with it. -Jonathan
