# 2021-04-11-15:32:20+0800 enable balance-region-scheduler

- Cause: TiKV CPU will increase until the region are balanced
- Operation:

```
./pd-ctl -u https://db-pd:2379 --cacert="/var/lib/pd-tls/ca.crt" --cert="/var/lib/pd-tls/tls.crt" --key="/var/lib/pd-tls/tls.key" scheduler add balance-region-scheduler
./pd-ctl -u https://db-pd:2379 --cacert="/var/lib/pd-tls/ca.crt" --cert="/var/lib/pd-tls/tls.crt" --key="/var/lib/pd-tls/tls.key" store limit 261394 5
./pd-ctl -u https://db-pd:2379 --cacert="/var/lib/pd-tls/ca.crt" --cert="/var/lib/pd-tls/tls.crt" --key="/var/lib/pd-tls/tls.key" store limit 261394 1
```

- Impact: CPU will goes up a little bit
- Recovery operation: N/A
