hsiang-c opened a new issue, #3362: URL: https://github.com/apache/datafusion-comet/issues/3362
### Describe the bug As https://github.com/apache/datafusion/issues/19144 indicates, most of DF's Spark expression do not report the nullability correctly. Spark 4.0 has a `nullIntolerant` method defined in [Expression](https://github.com/apache/spark/blob/branch-4.0/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/Expression.scala#L143-L148) and the comment is ```Scala /** * When an expression inherits this, meaning the expression is null intolerant (i.e. any null * input will result in null output). We will use this information during constructing IsNotNull * constraints. */ ``` I think Comet should have similar fix. ### Steps to reproduce _No response_ ### Expected behavior _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
