Cache realization method of interface calling

Abstract

The invention discloses a cache realization method of interface calling, which effectively integrates a centralized cache and a stand-alone cache. Interface version number information saved in a stand-alone Ehcache cache is used for monitoring timeliness of interface information in a stand-alone memory cache, an interface calling return result is preferentially acquired from the local stand-alone cache during interface calling, so that the local stand-alone cache can be made full use of to acquire the interface calling return result under the condition of low interface update frequency, the centralized cache can be used for acquiring the interface calling return result under the condition of high interface frequency, the data consistency of the stand-alone cache can be realized, the stand-alone cache can be made full use of, the pressure of the centralized cache is effectively reduced, the network transmission overhead is reduced, and the system resource waste is avoided.

Description

technical field [0001] The invention relates to caching technology, in particular to a caching implementation method of interface calling. Background technique [0002] At present, in large-scale, high-concurrency and high-load WEB systems in the Internet and other fields, caching technology is generally used to improve performance. Without the support of caching technology, it is impossible to solve the large concurrency problem of the WEB system. Even if it is solved, it will cost a lot of money. Therefore, an excellent caching solution is very important for large-scale high-concurrency systems. [0003] According to different system scales, there are two existing caching technologies, one is stand-alone caching and the other is centralized caching. Stand-alone caching means that the WEB application and the cache are the same application, which is the simplest caching strategy. HashMap and List used in Java-based programs can all be counted as the category of caching. Ce...

Problems solved by technology

However, in the centralized caching solution, all calls must be implemented by calling the cache server through the network. In this way, in the case of a particularly large number of calls, it will cause network congestion and even performance problems of the cache server itself.

At the same time, for interfaces that are not updated in real time (that is, the update frequency is low), such as basic data interfaces, etc., this kind of overhead is unnecessary, so it will cause waste of system resources
