  • Patent number: 11657091
    Abstract: The present disclosure provides a method and an apparatus for querying the shortest path of a graph, and a storage medium. The method includes: performing a breadth-first search in a distributed graph database with a start entity to be searched and an end entity to be searched as root nodes respectively, and obtaining a layer of new entities for each search; performing an intersection checking on the new entities and entities of the highest layer from a search set on an opposite side, so as to determine whether an intersection between the new entities and the entities of the highest layer exists; and when the intersection exists, determining intersection points, and performing path backtracking through the intersection points to find the shortest path from the start entity to the end entity.
