説明
Currently, the bottleneck of RawKV read is the scheduler thread, it runs 100% CPU while the raftstore runs 60%, the network, and disks are not full either.
Based on the flame graph[0] of the scheduler, we can easily find out that Prometheus consumes about 10% CPU time. 10% is not big but definitely not small, there is more room for the read performance!
