A rough guess on the best way to do this with cql, without looking too
deeply into it:
You would likely have to implement a custom load balancing policy within
the driver that only uses coordinator nodes and/or modify
refreshNodeListAndTokenMap() behaviour in ControlConnection.java (there
should a
1. The coordinator still store system data and hints, but they should not
store any user data since they are not part of ring.
2. We are using coordinator for thrift client. For cql based drivers, they
needs to talk to nodes in the ring, so I think coordinator mode won't work
for them.
