> Currently, DataFusion has the logical operator `isNull` and `IsNotNull`, but that operator has no physical implementation. Consequently, this operator cannot be used.
> The goal of this improvement is to add support to this operator on the physical plan.
> Note that these operators only care about the null bitmap, and thus should be implementable to all types supported by Arrow.
> Both operators should probably return a non-null `BooleanArray`.
