This is a nice quest not only to get familiar with Designer Cloud but also, to know how the behavior of the tools having the same name differs between each platform Desktop vs Cloud. With Designer Desktop, I would go with Tile tool to calculate Dense Rank. With Designer Cloud, I see a couple of way to do so.
Here is my solution !
I was surprised by the output of the tile tool. Fun challenge though :)
This one required me to use different tools than I would normally use with Designer Desktop. Also, requiring a sorting column for the Row ID tool removed a solution for me on this one. I get it has to do with sampling on the backend, but it's very frustrating sometimes.
Voila
