Yijie, As Davies said, it will take us a while to get to vectorized execution. However, before that, we are going to refactor code generation to push it into each expression: https://issues.apache.org/jira/browse/SPARK-7813
Once this one is in (probably in the next 2 or 3 weeks), there will be lots of expressions to create code-gen versions, and it'd be great to get as much help as possible from the community.
