Example 1 with ByNameToByIndexFieldAccessRule

use of org.apache.asterix.optimizer.rules.ByNameToByIndexFieldAccessRule in project asterixdb by apache.

the class RuleCollections method buildPlanCleanupRuleCollection.

public static final List<IAlgebraicRewriteRule> buildPlanCleanupRuleCollection() {
    List<IAlgebraicRewriteRule> planCleanupRules = new LinkedList<>();
    planCleanupRules.add(new SwitchInnerJoinBranchRule());
    planCleanupRules.add(new PushAssignBelowUnionAllRule());
    planCleanupRules.add(new ExtractCommonExpressionsRule());
    planCleanupRules.add(new RemoveRedundantVariablesRule());
    planCleanupRules.add(new PushProjectDownRule());
    planCleanupRules.add(new PushSelectDownRule());
    planCleanupRules.add(new SetClosedRecordConstructorsRule());
    planCleanupRules.add(new IntroduceDynamicTypeCastRule());
    planCleanupRules.add(new IntroduceDynamicTypeCastForExternalFunctionRule());
    planCleanupRules.add(new RemoveUnusedAssignAndAggregateRule());
    planCleanupRules.add(new RemoveCartesianProductWithEmptyBranchRule());
    planCleanupRules.add(new InjectTypeCastForSwitchCaseRule());
    planCleanupRules.add(new InjectTypeCastForUnionRule());
    // Needs to invoke ByNameToByIndexFieldAccessRule as the last logical optimization rule because
    // some rules can push a FieldAccessByName to a place where the name it tries to access is in the closed part.
    // For example, a possible scenario is that a field-access-by-name can be pushed down through UnionAllOperator.
    planCleanupRules.add(new ByNameToByIndexFieldAccessRule());
    return planCleanupRules;
}

Example 2 with ByNameToByIndexFieldAccessRule

use of org.apache.asterix.optimizer.rules.ByNameToByIndexFieldAccessRule in project asterixdb by apache.

    fieldLoads.add(new LoadRecordFieldsRule());
    fieldLoads.add(new PushFieldAccessRule());
