Examples of eu.stratosphere.compiler.dag.SinkJoiner

eu.stratosphere.compiler.dag.SinkJoiner
This class represents a utility node that is not part of the actual plan. It is used for plans with multiple data sinks to transform it into a plan with a single root node. That way, the code that makes sure no costs are double-counted and that candidate selection works correctly with nodes that have multiple outputs is transparently reused.

    } else if (graphCreator.sinks.size() > 1) {
      Iterator<DataSinkNode> iter = graphCreator.sinks.iterator();
      rootNode = iter.next();


      while (iter.hasNext()) {
        rootNode = new SinkJoiner(rootNode, iter.next());
      }
    } else {
      throw new CompilerException("Bug: The optimizer plan representation has no sinks.");
    }
