> 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.
