Abstract

The embodiment of the invention provides a distributed caching method and a distributed caching system, and relates to the field of data storage. The data access speed of the distributed caching system is increased. The method comprises the following steps that the distributed caching system acquires a data operation request of a service application, and performs hash operation according to a key value of data indicated to be operated by the data operation request to obtain the identification information of a virtual queue vBucket corresponding to the data; the distributed caching system acquires a corresponding relationship between the identification information of the vBucket and a caching service node, determines a first caching service node corresponding to the identification information of the vBucket according to the corresponding relationship, and allocates the data operation request to the first caching service node for corresponding data operation. The embodiment of the invention is used for distributed data caching.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a distributed cache method and system. Background technique [0002] With the continuous popularization of Internet technology, the amount of data transmitted on the Internet has experienced explosive growth. Among them, the application server reads the data from the database and displays it in the browser, and many network applications also save the data in the database. With the increase in the amount of data and the concentration of access, the burden on the database is increased and the response of the database is deteriorated, and the display delay of the website is affected. [0003] In order to solve the above problems, distributed cache technology is more and more widely used in the existing technology. Among them, the existing distributed cache mostly adopts a master-slave structure, that is, the master cache service node establishes a data directory for storing data stored b...
