Abstract

The invention relates to a method and system for synchronizing data between clusters in a graph database in real time and a medium, and the method comprises the steps: starting a monitor node on a main cluster, creating a learner copy, and adding the learner copy into a ramp group where a data fragment of the main cluster node is located; reading and processing a change data log of a master cluster node in real time through a monitor node, obtaining corresponding graph space information and an address of a pipeline node on a slave cluster, sending graph space data corresponding to the change data log to be synchronized to the pipeline node, and recording a log ID; and processing the graph space data through the pipeline node, sending the processed graph space data to the slave cluster node, and completing synchronization of the graph space data among the data fragments of the slave cluster based on the principle of raft consistency. According to the method and the device, the problem of how to ensure the reliability and the availability of the data in the graph database is solved, and the consistency of the data among the clusters is effectively ensured.

Description

technical field [0001] The present application relates to the field of graph databases, and in particular, to a method, system and medium for real-time synchronization of data between clusters in a graph database. Background technique [0002] With the rapid development of big data and artificial intelligence, ultra-large-scale relational networks are gradually being widely used in social recommendation, risk control, Internet of Things, blockchain, and security. Distributed graph database is one of the technical cornerstones of all these applications. , the amount of data that needs to be processed increases geometrically. For a graph database cluster that accommodates hundreds of billions of vertices and trillions of edges, to ensure high availability of data in real time, it is necessary to build a standby cluster and ensure real-time synchronization of data between the active and standby clusters. [0003] Because the data of the relational network changes in real time,...
