Do you mean you want to obtain a list of adjacent edges for every vertex? A
mapReduceTriplets followed by a join is the right way to do this. The join
will be cheap because the original and derived vertices will share indices.
There's a built-in function to do this for neighboring vertex propertie
What is the most efficient way to an RDD of GraphX vertices and their
connected edges? Initially I though I could use mapReduceTriplet, but I
realized that would neglect vertices that aren't connected to anything
Would I have to do a mapReduceTriplet and then do a join with all of the
vertices to p
