[jira] [Updated] (ARROW-10016) [Rust] [DataFusion] Implement IsNull
and IsNotNull
[ https://issues.apache.org/jira/browse/ARROW-10016?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jorge updated ARROW-10016:
--------------------------
Description:
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`.
