@InterfaceAudience.LimitedPrivate(value={"Coprocesssor","Phoenix"})
 @InterfaceStability.Evolving
public class RWQueueRpcExecutor
extends RpcExecutor

RPC Executor that uses different queues for reads and writes. With the options to use different queues/executors for gets and scans. Each handler has its own queue and there is no stealing.
