It seems that there is no specific information provided regarding the Pull Request for the Thanos project. To create a summary for an undefined Pull Request, I would need details such as the changes being proposed, the rationale behind them, the files affected, or any specific feature enhancements, bug fixes, or refactoring that is being addressed.

If you can provide more context or details related to the Pull Request, I would be more than happy to help you craft a summary!
