Review Comment:
Was wondering if the filter is partition filter or no filter at all and we
know the amount of files we are gonna scan and have enough confidence that we
will get those number of records can we set this to false then, hinting spark
that global limit is not required, though it will be a very niche use case and
maybe not worth it
