Embodiment Construction

[0044] The specific implementation manners of the present application will be further described in detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0045] figure 1 is a schematic structural diagram of a data synchronization system provided by an embodiment of this application, such as figure 1 As shown, the system at least includes: a data storage system 110 and an application system 120 .

[0046] The data storage system 110 is used to store data. For example: a credit directory is stored, and at least one credit-related data is stored in the credit directory.

[0047] The application system 120 refers to a system that subscribes to data stored in the data storage system 110 .

[0048] Optionally, when the application system 120 needs to subscribe to the data storage system 110, it sends a subscription request to the data storage sy...

Abstract

The invention relates to a data synchronization method and device and a storage medium, and belongs to the technical field of computers. The method comprises the following steps: acquiring a total synchronization indication; starting to execute data full-amount synchronization according to the full-amount synchronization instruction; obtaining a target data updating operation in the data full-amount synchronization process; after data full-amount synchronization is completed, carrying out secondary data synchronization according to the target data updating operation. The problem that data errors are likely to occur if data updating operation exists during existing data full-amount synchronization can be solved. Since the secondary data synchronization is carried out according to the data updating operation obtained in the data full-amount synchronization process after the data full-amount synchronization is finished, the data synchronization conflict in the full-amount synchronizationprocess can be avoided, and the data synchronization accuracy is improved.

Description

technical field [0001] The present application relates to a data synchronization method, device and storage medium, belonging to the technical field of computers. Background technique [0002] At present, many projects need to complete the aggregation of multi-party data such as public security, transportation, education, credit, etc., to achieve data centralization and data sharing, and have high requirements for data accuracy. In order to ensure data security or meet data subscription requirements, it is usually necessary to synchronize stored data to a designated location. [0003] Existing data synchronization methods include: synchronizing the full amount of data to a designated location at a certain point in time. Incremental synchronization monitors database operation logs and sends real-time data changes to the message subscription system. The system synchronizes data changes by listening to the message subscription system. [0004] However, during the first full ...
