Abstract

The invention relates to a distributed real-time graph construction and query method and a system based on Spark and Ignite. The method comprises the steps of starting Spark real-time graph construction and graph query tasks, loading fields of points and edges of a to-be-queried graph into an Ignite data set from a database, caching the fields, and creating indexes for the fields; generating a corresponding request parameter theme from the request parameter in the request initiated by the front end by using an encryption algorithm, and monitoring the request parameter theme; putting the request parameter theme into the request parameter, sending the request parameter theme to a request theme, and monitoring the request theme; obtaining data for calculation, and sending a calculation resultto the request parameter theme; and returning the obtained result data to the front end. By means of the distributed graph construction and storage functions of the Spark and the Ignite, graph construction and graph query can be conducted on hundred million-level or even ten billion-level data in real time, and the graph query time can be effectively shortened.

Description

technical field [0001] The invention relates to the field of data query, in particular to a method and system for constructing and querying distributed real-time graphs based on Spark and Ignite. Background technique [0002] With the rapid increase in the number of Internet users, the amount of data has grown exponentially in recent years. In this context, many big data analysis technologies have flourished, such as artificial intelligence, deep learning and knowledge graphs. The amount of data analyzed by the traditional knowledge map is small, and a single machine can meet the demand. But in the case of massive data, the calculation speed and storage space of a single machine will soon exceed the limit. At this time, distributed storage and computing will bring huge advantages to knowledge map analysis. [0003] However, in the case of hundreds of millions or tens of billions of data, traditional graph databases will be very slow in querying three-dimensional graphs, l...
