title: Examples for Topological Sorting on Large DAGs
body: <p>I am looking for real world applications where <strong>topological sorting</strong> is performed on <strong>large graph</strong> sizes.</p>
  
  <p>Some fields where I image you could find such instances would be bioinformatics, dependency resolution, databases, hardware design, data warehousing... but I hope some of you may have encountered or heard of any specific algorithms/projects/applications/datasets that require topsort.</p>
  
  <p>Even if the data/project may not be publicly accessible any hints (and estimates on the order of magnitude of potential graph sizes) might be helpful.</p>
