It appears that the Pull Request (PR) details were not provided, so I can’t create a summary without specific information about it. However, I can guide you on how to create a summary for a Pull Request in a project like thanos-io/thanos for an advanced developer.

A good PR summary should include:

  1. Title/Description: A concise title that captures the essence of the changes. Follow it with a detailed description about what the PR does, including the motivation behind it.

  2. Key Changes: Highlight the main changes made, including new features, bug fixes, or performance improvements. Use bullet points for clarity.

  3. Technical Details: Provide insights into implementation choices, algorithms used, or architectural considerations that may interest an advanced developer.

  4. Dependencies: Mention any external libraries, tools, or components that this PR depends on if applicable.

  5. Testing: Explain how the changes were tested, mentioning any test cases or scenarios covered by your tests.

  6. Impact: Discuss how this PR impacts existing functionality, any potential breaking changes, and how it fits into the overall architecture of the project.

  7. Next Steps: Optionally, outline any follow-up actions needed after the PR is merged, such as documentation updates or further enhancements.

If you have the details of the PR, feel free to share them, and I can assist in drafting a specific summary!
