> Nullability is lost in FamilyArgumentStrategy
> ---------------------------------------------
>
> Key: FLINK-38841
> URL: https://issues.apache.org/jira/browse/FLINK-38841
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / Planner
> Reporter: dylanhz
> Priority: Major
> Labels: pull-request-available
>
> Currently, in FamilyArgumentStrategy#inferArgumentType, if the actualType
> belongs to the expectedFamily, the method returns the actualDataType
> directly, ignoring the expectedNullability constraint.
> {code:java}
> // type is part of the family
> if (actualType.getTypeRoot().getFamilies().contains(expectedFamily)) {
> return Optional.of(actualDataType);
> }
> {code}
> This behavior is inconsistent with RootArgumentStrategy, where the
> expectedNullability is strictly enforced.
