DATA RETRIEVAL VIA INCREMENTAL UPDATES TO GRAPH DATA STRUCTURES

摘要

Certain embodiments involve tracking incremental updates to graph data structures and thereby facilitating efficient data retrieval. For instance, a computing system services a first query for one or more segments of computing devices, online entities, or both. The computing system services the first query by searching of a set of nodes from a graph data structure. The computing system receives a second query after the graph data structure has been modified. The computing system identifies, from a change list for tracking changes to the graph data structure, a subset of the nodes impacted by the modification to the graph data structure. The computing system services the second query by searching the subset of impacted nodes in the graph data structure.
