Method for realizing cross-regional data synchronization

Abstract

The invention aims to provide a method for realizing cross-regional data synchronization. When the client accesses the access point for the first time, the database feeds back user information (1), calculates service response according to required service data, and when new data is generated, the user information (1) is updated into user information (2) at the moment, and the access point encryptsthe user information (2), transmits the encrypted user information (2) to the client and stores the encrypted user information (2) in the client; meanwhile, the access point transmits the new data toa database for storage in real time; the client accesses any access point again; and the user information (2) is carried, so that the access point does not need to request data from the database, andthe service response can be directly calculated according to the service data in the user information (2), thereby solving the problem of access point data synchronization by utilizing the client resources, reducing the access frequency of the database and relieving the access pressure of the database.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method for realizing cross-regional data synchronization. Background technique [0002] With the increase in the amount of access data, the CDN solution is now used for static websites, and multi-site deployment is often used. CDN: Content Delivery Network is the content distribution network. CDN is a group of WEB servers distributed in different geographical locations, which are used to publish content to users more effectively. When optimizing performance, they will be selected according to the distance. The user accesses the nearest access point to directly obtain the cached data of the access point, and directly responds to the user request. However, for dynamic data requests, the access point server needs to combine policies and configurations to respond based on user data and some behaviors, so the access point still needs to obtain user information from the central server or c...

AI Technical Summary

Problems solved by technology

[0004] (1) If a centralized database method is adopted, there will be a communication delay between the access point and the database, which will also lead to slow access, and the access pressure of the database is very high;

[0005] (2) If the database is deployed separately at the access point, there will be a problem of data inconsistency between each database and the central database;

[0006] (3) If a cache database is deployed near each access point, there will be a problem of data inconsistency between the cache and the central database
