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/>.

Subject: Re: Cassandra proxy to control read/write throughput
The following presentation describes in detail a technique for using coordinator-only \
nodes which will give you similar behavior (particularly slides 12 to 14): \

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?
Thanks.
