  • Managing hybrid graph data storage and retrieval for efficient graph query execution
    Patent number: 11829419
    Abstract: A system for loading graph data from an external store in response to a graph query is disclosed. In some embodiment, given a graph database where all vertices are stored in memory and some but not all edges are stored in the external store, the system performs one of two methods. In the first method, the system iteratively expands a set of vertices that is initially specified in the graph query and collects all edges connected to the set of vertices, including edges stored in the external store, that satisfy a vertex constraint also specified in the query. In the second method, the system finds a set of vertices that satisfy the vertex constraint and collects all edges connected to the set of vertices, including edges stored in an external store.
