Subject Merge or minus Dataset API missing
Date Fri, 12 Feb 2016 15:48:29 GMT
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?
