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 addresses an inaccuracy in the TiKV configuration documentation by updating the description of the end-point-memory-quota parameter's default value. The change ensures that users have correct information regarding how this critical memory quota is calculated, thereby improving clarity and preventing potential misconfigurations.

Highlights

• Documentation Correction: The pull request corrects the documented default value for the end-point-memory-quota parameter in the TiKV configuration file.
• Default Value Clarification: The previous description incorrectly stated the default as '45% of total system memory, capped at 500 MiB'. The updated documentation now accurately reflects the default as 'the larger value between 12.5% of the total system memory and 500 MiB'.
