Cache synchronization method and device, electronic equipment and computer readable storage medium

Abstract

The embodiment of the invention discloses a cache synchronization method and device, electronic equipment and a computer readable storage medium. The cache synchronization method comprises the following steps: after monitoring that first preset information of a service system is changed on a local server, updating a first cache of the local server by utilizing the changed first preset information;Wherein the service system is distributed in a server cluster comprising the local server; Sending a first preset information change event to at least one other server in the server cluster so as toupdate a third cache of the at least one other server by utilizing the changed first preset information; And updating the second cache of the local server by using the first cache in response to the event that the third cache on the at least one other server is successfully updated. According to the method and the device, the real-time performance of cache updating is improved, and the dependenceon a persistent storage medium in the updating process and the one-time problem of the preset information updating process are avoided.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a cache synchronization method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] With the rapid development of business, business diversity and complexity have led to very complex business systems. When problems occur in business systems, it is difficult for human resources to find and locate the problems in the first place. Therefore, real-time management and control (management monitoring) of business systems must also be implemented. indispensable. The management and control system corresponding to the business system needs to realize the analysis of the collected data of the business system through distributed real-time computing. For the real-time computing of the management and control system, some information needs to be configured. When the preset information changes, how to quickly change the preset informat...

Problems solved by technology

However, the inventors of the present disclosure have found that there are at least two problems in this method: 1. The real-time nature of parameter configuration. In the method of regularly refreshing the cache, the event interval set by the timed task should not be too large, otherwise when the parameter configuration changes less, it is easy to It causes waste of resources, and the excessive time interval will lead to inconsistent parameter configuration in the service cluster, which affects the real-time calculation results of the business system; 2. The fault tolerance of parameter configuration is not good. When a parameter configuration error occurs, the configuration cannot be quickly rolled back To the original configuration to maintain the stability of real-time calculation
