Abstract

An embodiment of the invention provides a method and device for maintaining data consistency, an electronic device and a readable storage medium, which can solve the problem of data inconsistency between a cache server and a database server, are reliable, have high efficiency and can save a large amount of service server resources. The method for maintaining data consistency in the embodiment of the present invention includes the steps of copying and sending the modified data to a corresponding message queue server while modifying the data; receiving data from the caching server and / or the database server and placing the data in respective message queues; and obtaining data from the message queue server and processing the data according to the data consistency principle.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method, device, electronic equipment and readable storage medium for maintaining data consistency. Background technique [0002] In large-scale Internet e-commerce applications, in order to cope with high concurrency and high availability scenarios, the application data needs to be stored in the cache server and the database server at the same time, and the data of the cache server and the database server are allowed to be modified at the same time. Cause data inconsistency, affect business logic, and even lead to logic errors. [0003] There are two methods to solve the problem of data inconsistency in the prior art, one is to clear the cache: regularly clear the cache, and then copy the data in the database server to the cache server; the other is to traverse the data method: to traverse the cache regularly The data in the server and the database server, if inconsistent data is foun...
