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 the tidb_redact_log system variable. The change clarifies that this variable's scope is now strictly GLOBAL, meaning it can only be configured at the global level and no longer supports session-specific settings. This ensures consistency and accuracy in how the variable's behavior is described.
Highlights
tidb_redact_logsystem variable scope: The documentation for thetidb_redact_logsystem variable has been updated to reflect that its scope is now exclusivelyGLOBAL, removing theSESSIONscope option.

This change improves consistency and security by ensuring that log redaction is a cluster-wide setting, which is appropriate for a feature that handles sensitive information. The documentation change is accurate and aligns with best practices for such configurations. No further changes are needed.
