Reynold Xin updated SPARK-7813:
-------------------------------
Summary: Push code generation into expression definition (was: Push code
generation into expression definition themselves)
> Push code generation into expression definition
> -----------------------------------------------
>
> 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.
