 id="CreateAGraphProcessingPipeline"><h2><a href="#CreateAGraphProcessingPipeline">Create a Graph Processing Pipeline</a></h2><p>Using the example from the previous section, we create a three-stage pipeline that encapsulates the three stage tasks (<code>f1, f2, f3</code>) in three pipes. By finding a topological order of the graph, we can transform the node dependency into a sequence of linearly dependent data tokens to feed into the pipeline. The overall implementation is shown below:</p><pre class="m-code
