Abstract

Data specifying a new edge of a graph database may be received. A data store for storing the new edge may be identified from amongst a plurality of data stores utilized to store one or more portions of the graph database. Each of the plurality of data stores may be associated with a set of values corresponding to an aspect of edges of the graph database. The data store for storing the new edge may be identified based on the new edge being associated with a value corresponding to the aspect of edges of the graph database that is within a set of values corresponding to the aspect of edges of the graph database associated with the data store for storing the new edge.
