Description

Using RWQueueRpcExecutor, SimpleRpcScheduler lets us define separate queue/handlers to process write, read and scan requests. If this can be extended to have separate queue/handlers for multi get requests, it will help processing single get requests quickly where there is a mix of multi and single get workload. This is the case for multi put/single put as well. Any drawbacks in doing this segregation?
