Is there a better way we could do this? Maybe add something
upstream if necessary?
As I'm thinking of it, I don't know that this operation is necessarily well
defined. Just like with `limit` when you call it multiple times on a large
dataframe you get different results, I would expect different results from
multiple calls here.
If we do put this in, I would suggest adding more text to the description to
explain why this is an expensive operation - that it performs a collect to
determine the size of the dataframe.
