difference between rows

@codewizard

In Dataiku we do many things in a database like fashion not like a spreadsheet. Many databases do not guarantee an order for rows unless you specifically request it. So having a formula that references values in other rows before or after the current row can be challenging. This is because this concept of row ordering is not the general case inside of a database.

So for this type of use case where I’m trying to calculate values across rows. I have a tendency to use a window recipe. This recipe does work across rows.
