It seems that you referred to an “undefined Pull Request” for the Thanos project without providing specific details or a link. To create a summary for an advanced developer, I’ll need key details about the Pull Request, such as:

  1. Description/Title: What is the main aim of the PR?
  2. Changes: What files or components are affected? What kind of modifications are included (e.g., bug fixes, new features, performance improvements)?
  3. Impact: How do the changes affect the existing functionality or architecture?
  4. Testing: Are there any new tests included? How do they verify the changes?
  5. Related Issues: Are there any issues in the repository that this PR addresses?

If you can provide that information, I can generate a suitable summary for you.
