[jira] [Created] (SPARK-7813) Push code generation into expression definition themselves

Reynold Xin created SPARK-7813:
----------------------------------

             Summary: Push code generation into expression definition themselves
                 Key: SPARK-7813
                 URL: https://issues.apache.org/jira/browse/SPARK-7813
             Project: Spark
          Issue Type: Improvement
          Components: SQL
            Reporter: Reynold Xin
            Assignee: Davies Liu
            Priority: Critical


Right now we define all expression code generation in a single file. If we want to do code generation for most default expressions, it'd only make sense to push them into the expression definitions themselves (similar to "eval" method).

We would need to design an updated version of the expression API for that.
