Transparent and universal file cache system

Abstract

The invention relates to a file cache system, in particular to a transparent and universal file cache system. The system consists of five modules, namely a core module, a configuration management module, a massage queue management module, a communication module and a cache operation module. The whole system adopts a single-process and multithreading model, wherein the core module and the configuration management module operate in a thread 0; the communication module operates in a thread 1; the cache operation module operates in a thread 2; and the massage queue management module is shared globally. In the system, the core module is responsible for reading configuration information and initializing other functional modules. By the massage queue management module, other functional modules can realize mutual exclusion access to a massage queue. The system is communicated with a client by the communication module, receives a caching massage and delivers the cache massage to the cache operation module to process, and then returns a processing result to the client. By using the link modification technology, the transparent and universal file cache system can efficiently realize the filecache operation; moreover, by using the link modification technology, the system provides high transparency for application; and the modularization design and the excellent user interface make the system have excellent universality.

Description

technical field [0001] The invention relates to a file cache system, in particular to a transparent and general file cache system. The invention belongs to the field of computer technology. Background technique [0002] At present, with the rapid development of computer technology and the Internet, users' requirements for applications are not limited to functions, and the performance requirements for applications have gradually become the main factor affecting user experience. [0003] For enterprise websites, how to provide fast, stable and high-quality website experience for users from all over the world to improve user satisfaction and increase revenue is a strategically important topic for enterprises. American Gomez Network Company once conducted a survey of 2,000 users, and the results showed that when a website responds very slowly, 50% of users will give up visiting and turn to a competitor's website. With the gradual popularization of e-commerce, how to provide us...

Problems solved by technology

[0006] Looking at the implementation and application of file caching technology in these web server systems, there are generally the following problems: 1) relying on special hardware to build cache servers, the cost is relatively high; 2) The cached files are still stored in the disk of the cache server, and the disk access performance is still low; 3) The cache hit rate of the main memory of the cache server is still not guaranteed; 4) Each system adopts its own cache implementation scheme and is compatible with the application system It is associated with itself, not universal, and cannot be reused by other applications

Although many of the systems mentioned above have implemented and applied some kind of file caching technology, the implementation of each system is quite different, and they are all tightly coupled with the system itself, which is not universal.
