Jörn Horstmann commented on ARROW-10016:
----------------------------------------

[~jorgecarleitao] I would like to contribute this, if you haven't started already, since I already have an implementation of the kernels outside arrow.

>                 Key: ARROW-10016
>                 URL: https://issues.apache.org/jira/browse/ARROW-10016
>             Project: Apache Arrow
>          Issue Type: New Feature
>          Components: Rust, Rust - DataFusion
>            Reporter: Jorge
>            Priority: Major
>
> 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`.
