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

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

        inConns = ((BulkPartialSolutionPlanNode) node).getContainingIterationNode().getInputs().iterator();
        // because the partial solution has its own vertex, is has only one (logical) input.
        // note this in the task configuration
        targetVertexConfig.setIterationHeadPartialSolutionOrWorksetInputIndex(0);
      } else if (node instanceof WorksetPlanNode) {
        WorksetPlanNode wspn = (WorksetPlanNode) node;
        // input that is the initial workset
        inConns = Collections.singleton(wspn.getContainingIterationNode().getInput2()).iterator();
        
        // because we have a stand-alone (non-merged) workset iteration head, the initial workset will
        // be input 0 and the solution set will be input 1
        targetVertexConfig.setIterationHeadPartialSolutionOrWorksetInputIndex(0);
        targetVertexConfig.setIterationHeadSolutionSetInputIndex(1);
