It seems there was a mistake in providing the details of the Pull Request from the thanos-io/thanos repository. Without the specific content, context, or purpose of the Pull Request, it’s impossible to create an accurate summary.

To help you further, please provide the details or key points from the Pull Request you’d like summarized, such as:

• The main objectives of the changes.
• Key features or bug fixes being introduced.
• Impact on existing functionality or performance.
• Any specific areas of code affected.

Once I have that information, I’ll be able to create a suitable summary for an advanced developer.
