Examples of org.apache.flink.compiler.plan.SolutionSetPlanNode

org.apache.flink.compiler.plan.SolutionSetPlanNode
Plan candidate node for partial solution of a bulk iteration.

    // 2) Give the partial solution the properties of the current candidate for the initial partial solution
    //    This concerns currently only the workset.
    this.worksetNode.setCandidateProperties(worksetIn.getGlobalProperties(), worksetIn.getLocalProperties(), worksetIn);

    final WorksetPlanNode wspn = this.worksetNode.getCurrentWorksetPlanNode();
    
    // 3) Get the alternative plans
    List<PlanNode> solutionSetDeltaCandidates = this.solutionSetDelta.getAlternativePlans(estimator);
    List<PlanNode> worksetCandidates = this.nextWorkset.getAlternativePlans(estimator);
