Is there a base operator set letting all Math calculation of columns for each row work

[Xiaobo.Gu]

And then aggregate on the result of the function for each row?

That's users can write abitry math function applying to each row, then
aggredate the function result.

Great question :) As of now there is no that kind of operator. But we are trying to implement similar kind of operator in future releases and we think it will be a great addition
