Out of interest, has anyone stress tested the column expression node? How many expressions can it really handle (order or magnitute).
On a seperate note, wrapping many indivual node logics into one column expression node is concerning from a transparency and understandability perspective. Thoughts?
Yes I agree, if you put complexity into the /Column Expressions node it is not as transparent and self-documented from the outside. However there are use cases where it is a lot easier.
There is generally no limit of expressions, but as you noted, it gets less understandable. Also if I have many expressions, I would try to automate them more easily, so I do not have to change all of them in case my logic or data changes.
