Examples with ExtractGbyExpressionsRule org.apache.hyracks.algebricks.rewriter.rules.ExtractGbyExpressionsRule used on opensource projects

Example 1 with ExtractGbyExpressionsRule

use of org.apache.hyracks.algebricks.rewriter.rules.ExtractGbyExpressionsRule in project asterixdb by apache.

the class PigletRewriteRuleset method buildNormalizationRuleCollection.

public static final List<IAlgebraicRewriteRule> buildNormalizationRuleCollection() {
    List<IAlgebraicRewriteRule> normalization = new LinkedList<IAlgebraicRewriteRule>();
    normalization.add(new EliminateSubplanRule());
    // TODO: This rule is incorrect and has been removed. Its replacement in
    // Asterix (PushAggFuncIntoStandaloneAggregateRule)
    // is language-specific.
    // normalization.add(new IntroduceGroupByForStandaloneAggregRule());
    normalization.add(new BreakSelectIntoConjunctsRule());
    normalization.add(new PushSelectIntoJoinRule());
    normalization.add(new ExtractGbyExpressionsRule());
    return normalization;
