Hi to all, I have a use case where I have to merge 2 datasets but I can't find a direct dataset API to do that. I want to execute some function when there's a match, otherwise move on the not-null element. At the moment I can do this in a fairly complicated way (I want to avoid broadcasting because the dataset could be big): using 2 leftOuterJoin plus a union. Is there a simpler way?
Best, Flavio
