摘要
Techniques herein are for fast processing of path-finding queries in large graph databases. A computer system receives a graph search request to find a set of result paths between one or more source vertices of a graph and one or more target vertices of the graph. The graph comprises vertices connected by edges. During a first pass, the computer system performs one or more breadth-first searches to identify a subset of edges of the graph. The one or more breadth-first searches originate at the one or more source vertices. After the first pass and during a second pass, the computer system performs one or more depth-first searches to identify the set of result paths. The one or more depth-first searches originate at the one or more target vertices. The one or more depth-first searches traverse at most the subset of edges of the graph.
