> Now there are only metrics about total queue length and active rpc handler
> count. But in the RWQueueRpcExecutor, there are different queues and handlers
> for read/write/scan request. I thought it is necessary to add more metrics
> for RWQueueRpcExecutor. When use it in production cluster, we can adjust the
> config of queues and handlers according to the metrics.
