Review Comment:
My initial thought is that we can use `ExpressionUtil$selectsPartitions` to
test if the filter selects entire files. If so, we can simply find matching
files so that the sum of `recordCount` exceeds the pushed limit. It may be more
complicated for filters that only select some records within files. Let me
explore this PR more for that.
