Abstract

The invention provides a data increment synchronization method and device and terminal equipment. The method comprises the following steps: receiving a plurality of increment logs sent by a source end database; extracting table data related to the DML operation from the multiple incremental logs, generating a compression log based on the table data, and sending the compression log to each target end database, wherein the compression log is used for instructing the target end database to send out a first request when it is judged that the compression log is matched with the received query request, or instructing the target end database to send out a second request after the target end database receives the compression log for a preset time; and receiving a first request or a second request sent by each target end database, and sending a corresponding incremental log to the corresponding target end database according to the received first request or second request. According to the invention, data synchronization efficiency can be improved.

Description

Technical field [0001] The present invention belongs to the field of data synchronization, and more particularly, it is to relate to a data incremental synchronization method, apparatus, and terminal device. Background technique [0002] The development of information technology has increased data acquisition, storage, and processing tasks, and network-based data sharing has become an indispensable way to acquire data resources. [0003] In order to better implement data sharing, you need to synchronize the shared data, for example, in order to better implement data sharing between various civil affairs systems, data synchronization is required between various civil affairs systems. However, the amount of data involved in the civil affairs system is huge, and the civil society system across the country will cause data synchronization to cause the bandwidth pressure, and the efficiency of data incremental synchronization is reduced. Inventive content [0004] It is an object of t...
