The disclosed embodiments provide a system that searches a graph database. During operation, the system obtains a log-based representation of a graph database storing a graph, wherein the graph comprises a set of nodes, a set of edges between pairs of nodes in the set of nodes, and a set of predicates. Next, the system obtains a first query containing a first search pattern for searching the log-based representation. The system then matches the first search pattern to one or more records in the log-based representation. Finally, the system outputs, as a first result of the first query, the one or more records in a subgraph of the graph.

Pattern-based searching of log-based representations of graph databases

In order to request desired information from a graph database, a system executes a query against the graph database. The graph database may store a graph that includes nodes, edges between the nodes, and predicates to represent and store data with index-free adjacency. Moreover, the query may identify a first edge associated with a predicate that specifies one or more of the nodes in the graph. In response to the query, the system receives a result that includes a subset of the graph. Then, the system may verify the subset of the graph. In particular, the system may verify that the subset of the graph includes one or more particular edges, such as an edge with the predicate in the query. Furthermore, the system may verify that the subset of the graph includes data and/or associated structure in the portion of the graph.
