ShortestPaths

class ShortestPaths extends Arguments with WithAlgorithmChoice

Computes shortest paths from every vertex to the given set of landmark vertices. Note that this takes edge direction into account.

The returned DataFrame contains all the original vertex information as well as one additional column:

  • distances (MapType[vertex ID type, IntegerType]): For each vertex v, a map containing the shortest-path distance to each reachable landmark vertex.
