What is changed, added or deleted? (Required)

Fix wording in the explain walkthrough, the current working seems to imply that the initial performance is good (which it is not). The rest of the walkthrough is to improve the performance, so the changed wording seems more correct.

Which TiDB version(s) do your changes apply to? (Required)

Tips for choosing the affected version(s):

By default, CHOOSE MASTER ONLY so your changes will be applied to the next TiDB major or minor releases. If your PR involves a product feature behavior change or a compatibility change, CHOOSE THE AFFECTED RELEASE BRANCH(ES) AND MASTER.

For details, see tips for choosing the affected versions.

  • master (the latest development version)
  • v9.0 (TiDB 9.0 versions)
  • v8.5 (TiDB 8.5 versions)
  • v8.4 (TiDB 8.4 versions)
  • v8.3 (TiDB 8.3 versions)
  • v8.1 (TiDB 8.1 versions)
  • v7.5 (TiDB 7.5 versions)
  • v7.1 (TiDB 7.1 versions)
  • v6.5 (TiDB 6.5 versions)
  • v6.1 (TiDB 6.1 versions)
  • v5.4 (TiDB 5.4 versions)

Hello @aquarapid, 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!

Summary of Changes

This pull request addresses an inaccuracy in the explain-walkthrough.md documentation file. The original wording implied that the initial query performance was ideal, which is not the case. The change corrects this statement to reflect the actual performance and sets the stage for the subsequent optimization steps described in the walkthrough.

Highlights

  • Documentation Improvement: The primary change involves correcting a statement in the explain-walkthrough.md file to accurately reflect the initial query performance as 'not ideal'.
  • Clarity and Accuracy: The update ensures that the documentation aligns with the intended purpose of demonstrating performance optimization techniques.

Changelog

  • explain-walkthrough.md
    • Changed the phrase 'which is an ideal performance' to 'which is not ideal performance' to accurately describe the initial query execution time.

Hi @aquarapid. 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.
