Claim:
1. A computer-implemented method comprising: maintaining, by an online system, a cumulative feature graph on one or more first data stores and a plurality of incremental feature graphs on one or more additional data stores, the additional data stores providing faster data access than the first data stores, the first data stores communicatively coupled to the additional data stores, the cumulative feature graph and each of the plurality of incremental feature graphs storing feature information describing features, each feature associated with a source entity represented in the online system, a target entity represented in the online system, and a feature value based on interactions between the source entity and the target entity; updating the cumulative feature graph based on the plurality of incremental feature graphs by: providing a cumulative feature value of the cumulative feature graph to a module of the online system.
