Interesting. I would expect that when an expression is all nulls, it would still be an array of the type declared on the `DataType` and not a `NullArray`. Do you have an example where we get a `NullArray` but its `DataType` is not `DataType::Null`? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
