Abstract

The invention relates to a method and system for preventing edge suspension in a distributed graph database, and the method comprises the steps: creating a point ref-key data storage format, creating an edge ref-key data storage format, and enabling a point ref-key and an edge ref-key to be respectively associated with a corresponding point data-key and an edge data-key; and on the basis of the point ref-key and the edge ref-key, graph data stored in the distributed graph database are operated, the operation comprises edge insertion, and the edge insertion specifically comprises the steps of starting a transactional mechanism, inserting a forward edge into the distributed graph database and inserting a reverse edge into the distributed graph database after completion. According to the method, the problem that the hanging edge is easy to appear in the distributed graph database is solved, the hanging edge is ensured not to appear through the ref-key design, and the final consistency of the forward edge and the reverse edge is ensured.

Description

technical field [0001] The present application relates to the technical field of big data, and in particular, to a method and system for preventing dangling edges in a distributed graph database. Background technique [0002] With the rapid development of big data and artificial intelligence, super-large-scale relational networks are gradually being widely used in the fields of social recommendation, risk control, Internet of Things, blockchain, and security prevention and control. As one of the technical cornerstones of all these applications, big Storage and computing platforms for large-scale distributed relational networks have received increasing attention from academia and industry. This kind of relational network is usually based on Graph Theory in data structure. There are two core elements that constitute a graph: points (vertex or node, also known as nodes) and attributes on points, and edges (edges). , also known as associations or relationships) and attributes o...
