There are some caveats with coordinator only nodes. You can read about our experience in detail here<https://blogs.msdn.microsoft.com/anubhavk/2017/05/18/coordinator-nodes-are-they-useful/>.

Each application is connecting to its own cluster. I am thinking about abstracting the Cassandra IP from app drivers. App will communicate to one proxy IP which will redirect traffic to appropriate Cassandra cluster. The reason behind this thinking is to merge multiple clusters and control the read/write throughput from proxy based on the application. If anyone knows about pg_bouncer for Postgresql, I am thinking something similar to that. Have anyone worked in such a project? Can you please share some idea?
