> Could you please point to the test in Parquet/Spark which is doing this?
Wondering why we have such a test.
internal sql testing where the query selected none of any of the rows after
the push down filtering scanned them. This is a legitimate codepath, just one
which didn't get picked up in parquet itself. I'll need to look at those tests
there to see if there more we should parameterize on vectorisation
