Review Comment:
We also could just keep a mapping specific for duplicates. That shrinks down
how much work we need to do because instead of trying to group by every
referenced data file, we juust go through the duplicates set. It's maybe a
little more memory but if we consider that we expect duplicates to generally be
rare it feels like a generally better solution
