             Summary: Remove redundant comparison in comparison operator generated by FreeMarker template
                 Key: DRILL-993
                 URL: https://issues.apache.org/jira/browse/DRILL-993
             Project: Apache Drill
          Issue Type: Improvement
            Reporter: Jinfeng Ni
            Assignee: Jinfeng Ni
            Priority: Minor


In comparison operators generated by FreeMarker template, we may do two comparisons for a single operator.  The second comparison is actually redundant.

In stead, we should modify the FreeMarker template, and do one comparison. This would improve the performance of comparison operators.
