> 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.
