Hi @mittalrishabh. Thanks for your PR.

I'm waiting for a pingcap member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Code Review

This pull request adds documentation for three new TiKV configuration parameters: mvcc-read-aware-enabled, mvcc-scan-threshold, and mvcc-read-weight, introduced in versions v8.5.6 and v9.0.0. The review feedback highlights several improvements, including correcting inconsistent anchor links that referenced the wrong version number and refining the text for better conciseness by removing redundant words.
