# 2022-07-24-00:46:01+0800 Change PD default configuration for customer

- Cause: A customer scaled their cluster (id: 1379661944623214066) but the scaling process is too slow, we tune the PD parameters to accelerate this process
- Operation:

```
> kubectl exec -it -n tidb1379661944623214066 db-pd-0 -- sh
> cd /var/lib/pd-tls
> /pd-ctl --pd https://db-pd:2379 --cacert ca.crt --key tls.key --cert tls.crt store limit all 100
> /pd-ctl --pd https://db-pd:2379 --cacert ca.crt --key tls.key --cert tls.crt store limit 2485770 100000000 remove-peer
```

- Impact: The scaling process (migrate date regions) will be accelerated, correspondingly, the CPU usage of TiKV nodes will increase.
