I'm still in the experimentation stage so perhaps forgive this hypothetical question/idea. I am planning to load balance by putting haproxy in front of the cassandra cluster. First of all, is that a bad idea?
Secondly, if I have high enough replication and # of nodes, is it possible and a good idea to proactively cause GCing to happen? (I.e. take a node out of the haproxy LB pool, somehow cause it to gc, and then put the node back in... repeat at intervals for each node?)
