It seems that there is no specific content or details provided about a Pull Request in the Thanos project. To create an effective summary for an advanced developer, I’ll need key information such as:

  1. The purpose or goal of the Pull Request.
  2. Specific changes made (e.g., new features, bug fixes, optimizations).
  3. Any relevant code snippets or implementation details.
  4. The impact of these changes on the existing codebase or functionality.
  5. Any related issues or discussions in the project’s issue tracker that this PR addresses.

If you can provide additional details or context regarding the Pull Request, I would be happy to help you create a clear and informative summary!
