### First-time contributors' checklist
- [ ] I've signed [**Contributor Lice…nse Agreement**](https://cla-assistant.io/pingcap/docs-cn) that's required for repo owners to accept my contribution.
### What is changed, added or deleted? (Required)
### Which TiDB version(s) do your changes apply to? (Required)
**Tips for choosing the affected version(s):**
By default, **CHOOSE MASTER ONLY** so your changes will be applied to the next TiDB major or minor releases. If your PR involves a product feature behavior change or a compatibility change, **CHOOSE THE AFFECTED RELEASE BRANCH(ES) AND MASTER**.
For details, see [tips for choosing the affected versions (in Chinese)](https://github.com/pingcap/docs-cn/blob/master/CONTRIBUTING.md#版本选择指南).
