[jira] [Created] (SPARK-13996) Add more not null attributes for Filter codegen

             Summary: Add more not null attributes for Filter codegen
                 Key: SPARK-13996
                 URL: https://issues.apache.org/jira/browse/SPARK-13996
             Project: Spark
          Issue Type: Improvement
          Components: SQL
            Reporter: Liang-Chi Hsieh


Filter codegen finds the attributes not null by checking IsNotNull(a) expression with a condition {{if child.output.contains(a)}}. However, the current approach to checking it is not comprehensive. We can improve it.
