org.eigenbase.relopt.RelOptPlanner
A RelOptPlanner is a query optimizer: it transforms a relational expression into a semantically equivalent relational expression, according to a given set of rules and a cost model.

    this.driver = driver;
  }


  @Override
  protected RelOptPlanner createPlanner() {
    final RelOptPlanner planner = super.createPlanner();
    planner.addRule(EnumerableDrillRule.getInstance(driver == null ? null : driver.getClient()));


    // Enable when https://issues.apache.org/jira/browse/DRILL-57 fixed
    if (false) {
      planner.addRule(DrillValuesRule.INSTANCE);
      planner.removeRule(JavaRules.ENUMERABLE_VALUES_RULE);
    }
    return planner;
  }
