      $graphLookup should spill to disk when the size of the frontier and the visited set exceeds the maximum memory usage. In particular, DocumentSourceGraphLookUp::checkMemoryUsage() should be modified to spill if the size of the two data structures is too large. Second, any place where the frontier or visited set is iterated will need to be updated to use a file iterator if it has spilled to disk.
