I have four Cassandra nodes deployed. I have a Java application which acts as a client to the Cassandra cluster. Now, I want to see if I can use different network interfaces for the Inter-node communication and the Data transfer.
Can you shed some light on this?
Yes, you can do this. For inter-node communication you can specify IPs/interfaces via listen_address (or listen_interface, but not together) (conf), and for client->Cassandra communication - rpc_address (or rpc_interface) (conf)...
If necessary, you may need to set broadcast_address & broadcast_rpc_address as well, but it depends on the topology of your cluster.
