Example 1 with FDsAndEquivClassesVisitor

use of org.apache.hyracks.algebricks.core.algebra.operators.logical.visitors.FDsAndEquivClassesVisitor in project asterixdb by apache.

the class EnforceStructuralPropertiesRule method newPropertiesDiff.

private IPhysicalPropertiesVector newPropertiesDiff(AbstractLogicalOperator newChild, IPhysicalPropertiesVector required, boolean mayExpandPartitioningProperties, IOptimizationContext context) throws AlgebricksException {
    IPhysicalPropertiesVector newDelivered = newChild.getDeliveredPhysicalProperties();
    Map<LogicalVariable, EquivalenceClass> newChildEqClasses = context.getEquivalenceClassMap(newChild);
    List<FunctionalDependency> newChildFDs = context.getFDList(newChild);
    if (newChildEqClasses == null || newChildFDs == null) {
        FDsAndEquivClassesVisitor fdsVisitor = new FDsAndEquivClassesVisitor();
        newChild.accept(fdsVisitor, context);
        newChildEqClasses = context.getEquivalenceClassMap(newChild);
        newChildFDs = context.getFDList(newChild);
    }
    AlgebricksConfig.ALGEBRICKS_LOGGER.finest(">>>> Required properties for new op. " + newChild.getPhysicalOperator() + ": " + required + "\n");
    return newDelivered.getUnsatisfiedPropertiesFrom(required, mayExpandPartitioningProperties, newChildEqClasses, newChildFDs);
}

Example 2 with FDsAndEquivClassesVisitor
