I'm evaluating Cassandra as a storage mechanism for monitoring data: machine and process status reports, inventory, etc.
One of my concerns is bandwidth usage; I don't want Cassandra replication traffic swamping more important traffic. I want to know if there's a way to limit the bandwidth usage within Cassandra or if I have to resort to network-level QoS rules instead. QoS rules get a little complicated when you try to distinguish traffic within the data center from traffic to the outside; I was hoping to avoid that. I also would really like a way to limit access to the Thrift interface with at least some rudimentary username/password combination. I don't see a way to do that currently. Thanks for any help Ted
