Example 1 with PushLimitIntoOrderByRule

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

the class RuleCollections method buildPhysicalRewritesTopLevelRuleCollection.

public static final List<IAlgebraicRewriteRule> buildPhysicalRewritesTopLevelRuleCollection(ICcApplicationContext appCtx) {
    List<IAlgebraicRewriteRule> physicalRewritesTopLevel = new LinkedList<>();
    physicalRewritesTopLevel.add(new PushNestedOrderByUnderPreSortedGroupByRule());
    physicalRewritesTopLevel.add(new CopyLimitDownRule());
    // CopyLimitDownRule may generates non-topmost limits with numeric_adds functions.
    // We are going to apply a constant folding rule again for this case.
    physicalRewritesTopLevel.add(new ConstantFoldingRule(appCtx));
    physicalRewritesTopLevel.add(new PushLimitIntoOrderByRule());
    physicalRewritesTopLevel.add(new IntroduceProjectsRule());
    physicalRewritesTopLevel.add(new SetAlgebricksPhysicalOperatorsRule());
    physicalRewritesTopLevel.add(new IntroduceRapidFrameFlushProjectAssignRule());
    physicalRewritesTopLevel.add(new SetExecutionModeRule());
    physicalRewritesTopLevel.add(new IntroduceRandomPartitioningFeedComputationRule());
    return physicalRewritesTopLevel;
}
