Abstract

The invention discloses a distributed cache method and system based on an improved consistent hashing. Included are a plurality of node servers. Each node server comprises a main cache region and a copy cache region. For each node server, the main cache region is used for caching, according to a consistent hashing algorithm, data written by a user or in need of access on the node server; and the copy cache region is used for caching, according to the consistent hashing algorithm, data of the main cache region of the previous node server on a hashing ring constituted by all the node servers. The invention effectively improves the reliability and availability of the system, and can also avoid a waste of resources and reduce the number of times of cached data synchronization.

Description

technical field [0001] The invention belongs to the field of information systems, and in particular relates to a method and system based on an improved consistent hash distributed cache. Background technique [0002] With the development of the Internet, especially the mobile Internet, the number of users is increasing, and the response speed required is getting faster and faster. In order to speed up the access speed, a comparative method is to use cache in the information system. Cache technology stores hot data and shortens the distance between cluster object data and applications. It is a key technology to speed up data access and provide distributed data sharing. This technology plays a very important role in improving system scalability and ensuring system reliability. . [0003] A large number of distributed caches exist in information systems. There are two main types of distributed cache systems: [0004] One is that the cached content of each server is the same, ...
