Abstract

The invention discloses a data synchronization method and device, and relates to the technical field of computers. One specific embodiment of the method comprises the following steps: serving a data change message of subscription source data through message middleware, receiving the data change message of the source data, and storing the data change message in a temporary table; synchronizing thestatic offline data of the source data to a local data table; and obtaining and processing the data change message from the temporary table, and updating data corresponding to the data change messageto the local data table. According to the embodiment, the problem that comparison resources are wasted can be solved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for synchronizing data. Background technique [0002] When e-commerce develops to a certain stage, the basic data of e-commerce will generally be made into a service interface and provided to other business departments, and the specific information of the basic information can be queried according to the id. Since many other business departments now have the need for data analysis based on real-time data, such as real-time inventory analysis, real-time pricing analysis, etc., they all need to associate basic data for data screening and paging query. If you use the interface service query of the basic data, you must query all the data to perform paging, association, screening queries, etc., which will put pressure on the basic data platform services on the one hand, and on the other hand have a great impact on the real-time performance requirements. Impact. ...
