Embodiment Construction

[0032] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0033] The main idea of ​​the technical solution of the present invention is that in the large-scale data system, on the premise of ensuring the use of the cache system, facing the collective cache data, the content that needs to be updated in time can be quickly located from the huge cache system, and Ability to update all cached data related to it. Under this premise, it is also necessary to ensure that the cache efficiency of the cache system itself is not significantly affected, and to achieve a good balance between the two seemingly contradictory words of cache and timeliness.

[0034] The technical solution of the present invention is to establish two new cache areas in addition to the original cache data, and establish a cache-based data mapping relationship through three cache areas in total...

Abstract

The invention discloses a data base caching method. Besides an original caching data, two new caching areas are constructed, and the data mapping relationship based on caching is constructed through three caching areas; and in a large-scale data system, on condition that a caching system is ensured to be used, the content needing to be updated timely can be located fast in the huge caching systemfor the aggregate caching data, and all the caching data related to the content can be updated.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a database cache method. Background technique [0002] In network applications facing large-scale access, the database often becomes the bottleneck of the entire system. In order to reduce the pressure of database access, the current Internet applications widely use caching mechanisms such as MemCache to cache data, so as to reduce the number of accesses to the database by the application server and improve system response efficiency. At present, various file caches and memory cache systems are developing rapidly, providing many choices for application developers. These caches often use the Key-Value mapping mechanism, and each Key (key value or cache name) corresponds to a specific Value (storage Content), the application writes or reads the required data through a specific Key, and sets a certain length of cache expiration time, and the cache system maintains these cached da...
