It would be helpful to be able to write MagicETL formulas using window functions, similar to in beast mode. While the Rank & Window tile is often sufficient, there are some use cases where having this feature in the Formula tile would simplify the dataflow steps:
- Using a sum window function with unbounded rows
- This does not work consistently in the Rank & Window tile
- Creating multiple window functions with different partitions
- Users currently have to create a separate tile for each partition criteria, whereas it would be nice to contain these functions within a single tile
- Adding a case statement within the aggregation
- In current state this requires adding a calculated field in a forumla tile, then using it in a subsequent Rank & Window tile. It would be simpler to do it all at once in the original formula tile
