> compareTempOrDuplicateFiles uses a combination of attemptId and fileSize to
> determine which file(s) to keep.
> I've seen instances where this function throws an exception due to the fact
> that the newer attemptId file size is less than the older attemptId (thus
> failing the query).
> I think this assumption is faulty, due to various factors such as file
> compression and the order in which values are written. It may be prudent to
> trust that the newest attemptId is in fact the best choice.
