Technically possible but not recommended. Beside making this node a
single point of failure, you assuredly add more latency to every
request. Also each request has memory overhead, one node will have the
sum overhead of all the requests it is not scalable. Also this node
can become a bandwidth limit.

One of the reasons to chose cassandra is it does NOT have a
master/queen node that all requests are proxied through.
