Distributed real-time graph construction and query method and system based on Spark and Ignite

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 ca
