Embodiment Construction

[0024] figure 1 It is a flow chart of Embodiment 1 of the data segmentation method of the distributed graph computing system of the present invention, as shown in figure 1 As shown, the method includes:

[0025] Step 101, according to a preset algorithm, determine the similarity measurement value between each data node in the data to be processed and its own first adjacent nodes;

[0026] The method provided in this embodiment is applicable to a scenario where a distributed data processing system is used for data segmentation and storage of large-scale graph-structured data, and multiple processing hosts are set in the distributed data processing system. It is worth noting that after the system receives a large amount of data to be processed, the existing distributed processing method can be used to distribute and store the data to be processed in multiple processing hosts in advance, and the method provided in this embodiment Processing can be performed on the data to be pr...

Abstract

The invention provides a data segmenting method and system of a distributed graph calculating system. The data segmenting method includes determining a similarity measurement value between each data node and an own first adjacent node in to-be-processed data; acquiring appearing times of a label of each first adjacent node, and determining whether at least two labels identical in appearing times exist or not; if yes, determining second adjacent nodes corresponding to the labels, and determining a label of each data node according to a similarity measurement value between each data node and the corresponding second adjacent node; dividing the data nodes with a same label into a same community, and storing the data nodes belonging to the same community into a same processing host. Community dividing of the data nodes is realized by taking similarity features among the data nodes into full consideration and on the basis of the labels, and operation expenditure is saved; the data nodes close in relationship are distributed into the same processing host, so that expenditure in communication among different processing hosts is reduced.

Description

technical field [0001] The invention belongs to the field of data processing, and in particular relates to a data segmentation method and system of a distributed graph computing system. Background technique [0002] In recent years, massive data generated in many fields represented by the Internet, high-energy physics, and computational biology have put forward higher requirements for data processing systems. Among these massive data, graph-structured data composed of nodes and edges is an important data structure that can effectively represent data relationships in many different fields. For example, social network data can be represented as a graph-structured data, where nodes represent Users, and edges represent the relationship between users. For example, if two users follow each other, it means that there is an edge between the two corresponding nodes. Similarly, the web page data of the Internet can also be represented as a graph structure data. Nodes represent web pa...
