Hello, quarry currently retains query results forever. This proves to be a problem when removed data is retained in quarry. In order to improve this while still leaving results accessible, results older than 90 days will be removed. The queries will not be impacted by this change. And the results can of course be regenerated (with current data) at any time by resubmitting the query.

The plan is for this to go into effect in later October (2024-10-21), could go in earlier but I won't be here until then.
Thank you!
