Abstract

The invention relates to a data synchronization system, a method, a device and a storage medium, belonging to the technical field of data synchronization. The system comprises a core domain and an n-level service domain. At least one service domain comprises m platform domains, and the core domain is located at the upper level of the n-level service domain; the core domain, configured to obtain adata update request sent by at least one subordinate service domain; executing a data update operation according to the data update request; acquiring a data update path and generating a data update message according to the data update path; writing a data update message into a message queue subscribed by a target service domain of a first level indicated by a data update path through a core domain daemon; a target platform domain in the target service domain of the i-th level for obtaining a data update message in a subscribed message queue through the i-th daemon; executing a data update operation according to the data update message. The data synchronization system, the method, the device and the storage medium can solve the problem of data conflict; Ensure the consistency of the updated data.

Description

technical field [0001] The application relates to a data synchronization system, method, device and storage medium, and belongs to the technical field of data synchronization. Background technique [0002] Distributed database refers to the use of high-speed computer network to connect multiple physically dispersed data storage units to form a logically unified database. A distributed database consists of multiple levels of service domains and a core domain on the upper layer of the service domain. Each service domain can include multiple platform domains to form a cluster to provide services for users; each service domain can also have multiple user domains . For example: provide users with video conferencing services through distributed databases. [0003] In a typical distributed database deployment method, the data between different service domains at the same level are independent of each other; the platform domain under each level of service domain contains all the d...
