Cache data synchronization method and device, equipment and storage medium

Abstract

The invention discloses a cache data synchronization method, device and equipment and a storage medium, and is applied to a distributed message middleware system.The method comprises the steps that target cache data in a main server of a remote dictionary service cluster is obtained; the target cache data is the cache data obtained after the application server stores the corresponding changed service data to the main server after the service data is changed; broadcasting the target cache data to each client of the distributed message-oriented middleware system through a server of the distributed message-oriented middleware system; and controlling each client of the distributed message-oriented middleware system to transmit the acquired target cache data to a corresponding slave server, so that each slave server stores the acquired target cache data to a local cache space. Through the technical scheme of the invention, the pressure of the application server and the main server can be reduced, the real-time synchronization of the cached data is realized, and the consistency of the data is ensured.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a buffer data synchronization method, device, equipment and medium. Background technique [0002] In order to improve the access speed of the system in the application system, a cache mechanism is often added at the application level, that is, the query data is stored in memory. Redis (Remote Dictionary Server, remote dictionary service) is an important memory database for cache data management. The management of data cache in the multi-service cluster mode must not only ensure the consistency of data, but also ensure the real-time performance of data. Timeliness and reliability are a basic requirement for cache synchronization. The synchronization methods of cached data in the existing remote dictionary service can be divided into the following types: [0003] (1) if figure 1 As shown, the application server is connected to multiple Redis servers, and the multiple Re...

Problems solved by technology

[0007] In view of this, the purpose of the present invention is to provide a cache data synchronization method, device, equipment and medium, which can solve the problem of high pressure on the master server when a master server is connected to multiple slave servers, and ensure the consistency of the cache data. The specific plan is as follows:
