Right, my point is that an accurate logical null count can be very expensive to compute, whereas it is much cheaper to instead determine the existence of any nulls. Whilst this won't serve every use-case, my question is whether DF actually needs accurate null counts all the time, or whether most of the time it is just using them as a proxy for nullability. -- This is an automated message from the Apache Git Service.
