[jira] [Created] (DRILL-937) Boolean operators should use short-circuit evaluation.

Jinfeng Ni created DRILL-937:
--------------------------------

             Summary: Boolean operators should use short-circuit evaluation. 
                 Key: DRILL-937
                 URL: https://issues.apache.org/jira/browse/DRILL-937
             Project: Apache Drill
          Issue Type: Improvement
            Reporter: Jinfeng Ni


When Drill evaluate a boolean operator ('and', 'or'), it should use the short-circuit evaluation approach : when one branch is sufficient enough to decide the final result, Drill should stop evaluating the other branches.  This should help improve the performance of filter operator, when it contains a complex boolean operator.
