Embodiment Construction

[0039] Specific embodiments of the present invention will be described in detail below. It should be noted that the embodiments described here are for illustration only, and are not intended to limit the present invention.

[0040] The idea of ​​the present invention is to improve the architecture between the cache server and the WEB server, divide multiple cache servers into at least two server groups, and store the cache data to be cached into corresponding nodes in the at least two cache server groups .

[0041] According to an embodiment of the present invention, the architecture of the distributed cache system of the present invention is as follows image 3 As shown, multiple cache servers are divided into m server groups, where m>1, that is, they can be divided into two server groups or more than two server groups, and each service group has at least one server node, and each cache server The cache server nodes of the cluster may be the same or different, as long as th...

Abstract

The invention discloses a distributed cache system, a data caching method and an inquiring method of cache data. The distributed cache system comprises at least two cache server farms, wherein each cache server farm is provided with at least one cache server node, one of the at least two cache server farms and one cache server node of the cache server farm respective serve as the main cache server farm and the main cache server node of the cache data, the other cache server farm and one of the cache server nodes serve as the backup cache server farm and the backup cache server node of the cache data, and the main cache server node and the backup cache server node save the same cache data. The invention can ensure the high reliability of the cache data in the cache server farm, and improvethe quality of the web service.

Description

technical field [0001] The invention relates to the field of internet data cache, in particular to a distributed cache system, a data cache method and a cache data query method. Background technique [0002] In the field of Internet applications, data caching technology is very important, not only to ensure the scalability of data caching, but also to ensure the performance and reliability of data caching. Most similar caching systems can solve the scalability problem, but they cannot solve the reliability of the cache well. For the caching of commonly used data, sessions and other information, high reliability is required. [0003] A cache architecture such as figure 1 As shown, the WEB server and the cache server are integrated, that is, the data is cached in the memory without network communication, so when the WEB server needs to be restarted, the cached data of the client is also lost; not only that, because the same The data to be cached on different WEB servers, so ...
