-----------------------------
Summary: [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
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 this operator only cares about the null bitmap, and thus should be
implementable to all types supported by Arrow.
Both operators should return a non-null `BooleanArray`.
