Description
Bug Report
What did you do?
Run sysbench read_only workload.
What did you expect to see?
The hot region is balanced and the number of the hot regions is almost the same.
What did you see instead?
From the hot read in pd-ctl:
"104": {
"total_flow_bytes": 12236445.15,
"total_flow_keys": 50156.25,
"regions_count": 1,

We find there is only one hot region in store 104 and the region id is 186247997.
Use pd-ctl region 186247997:
