Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] In a typical configuration of the present application, each module and trusted party of the system includes one or more processors (CPU), input / output interface, network interface and memory.

[0037] Memory may include non-permanent storage in computer readable media, in the form of random access memory (RAM) and / or nonvolatile memory such as read only memory (ROM) or flash RAM. Memory is an example of computer readable media.

[0038] Computer-readable media, including both permanent and non-permanent, removable and non-removable media, can be implemented by any method or technology for storage of information. Information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static random access memory (SRAM), dynam...

Abstract

Compared with the prior art, the invention discloses a method for updating cache data in a distributed cache system. The method includes the steps: when a triggering condition is satisfied, updating cache failure time and / or cache data corresponding to a cache keyword based on the cache keyword of the cache data of the distributed cache system, the cache failure time being updated based on currenttime and cache failure duration. The method guarantees that the distributed cache system reasonably keeps the storage duration of the hotspot cache data, and the low-frequency cache data can be removed in time, and the storage space utilization efficiency of the distributed cache system is improved while the cache data use efficiency of the distributed cache system is guaranteed.

Description

technical field [0001] The present application relates to the technical field of computer data processing, and in particular to a technique for updating cached data in a distributed cache system. Background technique [0002] In large-scale Internet applications, due to the requirements of high concurrent access, fast response, dynamic expansion, and easy maintenance, in order to reduce the burden on the database, a distributed cache system is usually used, such as redis (Remote Dictionary Server, remote dictionary service). When building a distributed cache system application, a reasonable expiration time is often set for the cache data stored in it. The cache system will regularly clean up the expired cache data and release the storage space occupied by the expired cache data to ensure Sustainability of the cache system. However, in a high-concurrency access scenario, when a large number of requests fail to obtain cached data due to cache data expiration and other reasons...
