Might be a big ask, but here’s an example:
Importing meta ads analyics per day.
There will be a lot of duplicates of days, and lots of duplicates of ad id, but if the ad id AND the name is the same, it should skip the import.
This is possible clean using automations and autolinking, but im worried about using autolinking on self relations in a huge dataset, as it automatically links to itself by default, so it will cause lots of autolinking triggers.
