1. A processor-implemented method of improving a computer system, the processor-implemented method comprising: receiving, by the processor, a data stream that describes graph nodes in a non-hierarchical graph database, wherein each of the graph nodes represents a synthetic context-based object, and wherein synthetic context-based objects are generated by: associating, by the processor, a non-contextual data object with a context object to define a synthetic context-based object, wherein the non-contextual data object ambiguously relates to multiple subject-matters, and wherein the context object provides a context that identifies a specific subject-matter, from the multiple subject-matters, of the non-contextual data object, wherein the synthetic context-based object, the non-contextual data object, and the context object are in a same processing and storage logic, and wherein the synthetic context-based object points to the non-contextual data object and the context object; defining, by the processor, multiple graph node clusters from the graph nodes in the non-hierarchical graph database, wherein the multiple graph node clusters share a common non-contextual data object; generating, by the processor, a cluster edge between two graph node clusters from the multiple graph node clusters in the non-hierarchical graph database, wherein the cluster edge describes a relationship between the two graph node clusters by identifying the common non-contextual data object; transmitting, by the processor, only information in the cluster edge to a party that is not allowed to view contents of the graph nodes in the non-hierarchical graph database, wherein transmitting only the information in the cluster edge enhances security of the non-hierarchical graph database; communicating, by the processor, the information from the cluster edge without the content of the graph nodes to a cache at a remote location, wherein communicating the information from the cluster edge without the content of the graph nodes reduces communication bandwidth consumption for a network that is coupled to the cache, and wherein communicating the information from the cluster edge without the content of the graph nodes reduces an amount of storage consumed in the cache; and executing, by the processor, a computation using only information stored in the cache that came from the cluster edge without the content of the graph nodes, wherein execution of the computation is improved by using only information from the cluster edge without the content of the graph nodes.
