It seems that there is no information available about the specific Pull Request (PR) you are referring to for the project thanos-io/thanos. To summarize a PR effectively, I would need details such as:

  1. Title of the PR: What is the main goal or purpose?
  2. Description: What changes or additions does it propose? Any specific issues it addresses?
  3. Files Changed: What files are modified?
  4. Review Comments: Any significant feedback from reviewers?
  5. Context: Is there any related issue or previous PR that this is associated with?

If you can provide this information, I’d be able to help create a meaningful summary tailored for an advanced developer.
