Cache system hotspot data access method and device, equipment and storage medium

Abstract

The invention relates to a cache system hotspot data access method and device, computer equipment and a storage medium. The method comprises the following steps: receiving an access request of a cachesystem, wherein the access request carries a to-be-accessed data identifier; when the to-be-accessed data corresponding to the to-be-accessed data identifier is in the candidate hotspot data list, obtaining a preset routing scheduling rule; and routing the access request to a target fragment according to a preset routing scheduling rule, responding the access request through the target fragment,acquiring an access result corresponding to the to-be-accessed data identifier, wherein the target fragment is not a fragment specially used for processing the access request corresponding to the to-be-accessed data identifier. By adopting the method, the flow of the fragment where the hotspot key is located can be dispersed, so that uniform access of the hotspot key is realized, and the access efficiency of the cache system is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a cache system hotspot data access method, device, computer equipment and storage medium. Background technique [0002] Redis is a distributed K-V (key-value key-value pair) cache system widely used by enterprises. When accessing the system, it will calculate a fragment according to the hash (hash function) of the key (key) to store Take this K-V. However, in practical applications, during some peak hours, a large number of requests for the same Key (maybe corresponding to a certain promotional product, hot news, hot comments, etc.) of the application, this key can be called a hot key, according to the hot key hash, all access requests will fall into the same shard, and the load on this shard will be severely increased, resulting in long response time and low access efficiency. Contents of the invention [0003] Based on this, it is necessary to address the above-m...
