Abstract
Techniques are provided for updating in-memory property graphs in a fast manner, while minimizing memory consumption. A graph is represented as delta compressed sparse rows (CSR), in which its data structure stores forward edge offsets that map reverse edges to forward edges, enabling fast traversals of graph edges in forward and reverse directions. To support fast graph updates, delta logs are used to store changes to the graph. In an embodiment, a base version of the graph data structure is initially loaded or created, and subsequent versions of the graph are created from the reference to the initial graph and a delta log data structure that records the changes compared to the base version of the graph.
