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 updates the documentation for sync-diff-inspector to specify an additional permission requirement. It clarifies that the PROCESS permission is now needed when comparing data between two TiDB clusters, allowing the tool to access essential cluster metadata. This ensures users have accurate information regarding necessary database privileges for successful tool operation.

Highlights

  • New Permission Requirement: The sync-diff-inspector tool now requires the PROCESS permission when both the upstream and downstream databases are TiDB clusters.
  • Purpose of PROCESS Permission: This PROCESS permission is necessary for sync-diff-inspector to query the INFORMATION_SCHEMA.CLUSTER_INFO table, which is crucial for its operation in a dual-TiDB environment.
  • Documentation Update: The sync-diff-inspector-overview.md documentation has been updated to reflect this new permission requirement, ensuring users are aware of the necessary grants.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.
