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

An RpcExecutor that will balance requests evenly across all its queues, but still remains efficient with a single queue via an inlinable queue balancing mechanism. Defaults to FIFO but you can pass an alternate queue class to use.
