Davies Liu created SPARK-13404:
----------------------------------

             Summary: Create the variables for input when it's used
                 Key: SPARK-13404
                 URL: https://issues.apache.org/jira/browse/SPARK-13404
             Project: Spark
          Issue Type: Improvement
          Components: SQL
            Reporter: Davies Liu
            Assignee: Davies Liu


Right now, we create the variables in the first operator (usually InputAdapter), they could be wasted if most of rows after filtered out immediately.

We should defer that until they are used by following operators.
