Problems solved by technology

[0005] In the prior art, when the MapReduce system processes the graph data, it only calculates the data item by item for the input file in the Map stage. In the process of processing the graph data, it shows that a single vertex is used as the calculation object, and each vertex contains itself and Outbound information, during each round of MapReduce operations, messages are limited to one-step transmission along the outbound edge for the next round of MapReduce operations. When the scale of graph data is large, multiple rounds of MapReduce operations are required. Inefficient processing of graph data

Abstract

Embodiments of the invention disclose a graph data processing method and apparatus. The method comprises the steps of determining to-be-processed graph data, and dividing a graph corresponding to the graph data into a plurality of sub-graphs; and dispatching computing nodes in a MapReduce system, and performing multi-round MapReduce operations on the graph data to obtain a processing result of the graph data, wherein each Map computing node in the MapReduce operation is used for processing vertexes with a mutual connection relationship in one of the sub-graphs. According to the method and the apparatus provided by the embodiments of the invention, the graph data processing efficiency can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of data processing, and in particular, to a method and device for processing graph data. Background technique [0002] A graph is an abstract data structure that can describe rich information and the dependencies between information. There are many algorithms based on graph data in the prior art, such as the shortest path algorithm, graph simulation algorithm, web page ranking algorithm, and breadth-first search algorithm. Applications of graph data and its associated algorithms are ubiquitous, such as social network analysis, semantic web analysis, bioinformatics, and traffic navigation. [0003] With the rapid development of these applications, the scale of the graph data they involve has also become larger and larger, with hundreds of millions of vertices and billions of edges at every turn. How to efficiently store and process large-scale graph data has also attracted more and more attentio...
