A method to realize cross-regional data synchronization

Abstract

The purpose of the present invention is 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 the user information ①, calculates the service response according to the required service data, and generates new data. At this time User information ① is updated to user information ②, the access point encrypts the user information ② and transmits it to the client, and stores it in the client; at the same time, the access point transmits the new data to the database for storage in real time; the client accesses any access again When pointing, bring user information ②, so that the access point does not need to request data from the database, and can directly calculate the service response based on the business data in the user information ②, so that the use of client resources solves the data synchronization problem of the access point , can reduce the number of visits to the database, and ease the pressure on database visits.

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
