Summary of Changes

Hello @ti-chi-bot, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request primarily focuses on enhancing the documentation for TiDB's Placement Driver (PD) configuration. It introduces a substantial number of new dynamic configuration parameters and provides more detailed explanations for specific settings, aiming to offer a more complete and up-to-date reference for users managing TiDB clusters.

Highlights

  • Updated Parameter Descriptions: Refined the description for an existing parameter (schedule.patrol-region-interval) for improved clarity and consistency.
  • Detailed Configuration Documentation: Included a new detailed section for the max-movable-hot-peer-size parameter in the PD configuration file, providing its purpose, default value, and unit, and marking it as 'New in v6.1.0'.
