    @srowen  Thanks for the summary.
    For the external API I wouldn't mind using (i, j, value) -- It results in larger files
and a `groupBy` to get to a row / column but I agree that this is the most compatible format
across various tools. On a related note is there an external representation that GraphX uses
that can be leveraged ? /cc  @jegonzal @ankurdave
    About the top 3 ideas, I'd also prefer (2) first and then (1). I am not sure what the
fa├žade is buying us as these are internal library calls that we can change going forward.
