It seems there is no specific information provided regarding the pull request you want summarized from the Thanos project. A pull request usually includes details like the changes made, the reasons behind those changes, any related issues, and the impact on the existing codebase.

To create a meaningful summary for an advanced developer, I’d need details such as:

  1. Title of the Pull Request: What is the focus of this PR?
  2. Description: What changes or features does this PR introduce?
  3. Files Changed: What files were modified, added, or deleted?
  4. Related Issues: Are there any specific issues or feature requests this PR addresses?
  5. Context: Any additional context or notes provided by the author?

If you can provide any of this information, I can create a well-structured summary for you.
