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 refines the tidb-performance-tuning-config.md documentation by enhancing the clarity and accuracy of TiFlash configuration instructions. The primary goal is to ensure users apply the correct settings to the appropriate TiFlash components, thereby improving the overall usability and correctness of the performance tuning guide.

Highlights

  • Documentation Clarity: Renamed the "TiFlash configurations" section to "TiFlash-learner configurations" in tidb-performance-tuning-config.md for improved accuracy and clarity.
  • Configuration Correction: Updated the TOML configuration section from [raftstore-proxy.server] to [server] for the snap-io-max-bytes-per-sec parameter within the TiFlash configuration example, ensuring correct syntax and application.
