--------------------------------------
Assignee: Jörn Horstmann
> [Rust] [DataFusion] Implement IsNull and IsNotNull
> --------------------------------------------------
>
> 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
> Assignee: Jörn Horstmann
> 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`.
