             Summary: Add IsNotNull constraints for expressions with an inequality
                 Key: SPARK-13759
                 URL: https://issues.apache.org/jira/browse/SPARK-13759
             Project: Spark
          Issue Type: Sub-task
            Reporter: Sameer Agarwal
            Priority: Minor


Support for adding `IsNotNull` constraints from expressions with an inequality. More specifically,
if an operator has a condition on `a !== b`, we know that both `a` and `b` in the operator
output can no longer be null.
