Data synchronization method, data synchronization apparatus, computer device, and storage medium

Abstract

The invention provides a data synchronization method, a data synchronization apparatus, a computer device, and a storage medium. The data synchronization method comprises the following steps: receiving first data synchronization request information, wherein the first data synchronization request information comprises client data version information; comparing the latest data version information with the client data version information, and extracting corresponding service data that need to be synchronized; and compressing the service data to write the same in a file stream so as to form a service data file, and transmitting the service data file to a client corresponding to the first data synchronization request information in the form of file. By adoption of the technical scheme of the invention, on one hand, the repeated processing of multiple intermediate links is reduced, and the risk of data truncation is reduced, and on the other hand, by adoption of the file form transmission, continuous transmission can be performed even in the case of poor network quality, and the stability of synchronous data transmission is improved, furthermore, the time of data synchronization is shortened, the efficiency of data synchronization is improved, and it is conducive to improving the consistency of data synchronization.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a data synchronization method, a data synchronization device, a computer device and a computer-readable storage medium. Background technique [0002] The computing power and storage capacity of mobile terminals are relatively limited, and all application data cannot be saved, so mobile applications need to exchange a large amount of data when using them. It is unrealistic to obtain all data from the server every time a mobile application is used. The terminal will store commonly used and basic application data to improve the running speed of the mobile application. How to ensure that the application data on multiple mobile terminals is consistent has become an important prerequisite for the correct operation of the mobile application. [0003] In related technologies, the data synchronization method needs to go through data synchronization request, data extracti...

Problems solved by technology

[0003] In related technologies, the data synchronization method needs to go through data synchronization request, data extraction, data conversion, data encryption, data compression, data retransmission, data decompression, data decryption, data conversion, data analysis, data retransmission every time data synchronization is performed. Stored in the warehouse, the data synchronization task can be completed with one request for small batches of data, but when it involves a large amount of data, it is easily affected by communication protocol problems, network problems, etc., resulting in data synchronization failure

However, the paging technology for data is likely to increase the time of data synchronization due to multiple requests, and the efficiency of data synchronization is low, which may easily lead to inconsistency of data synchronization
