Abstract

The invention provides a cluster cache sharing method, system and device and a storage medium, and the method comprises the steps that a newly added service node obtains a service node list from a registration center, and each service node in the service node list maintains heartbeat communication with a corresponding front service node; the newly added service node queries a front service node from the service node list; the newly added service node sends a heartbeat request to the front service node; and the newly added service node updates the service node list of the registration center. The invention provides a cluster cache comprising a plurality of service nodes; mutual perception of all the service nodes in the cluster is achieved based on a heartbeat mechanism among the service nodes, a complete service node list is maintained, the management of the service nodes is facilitated, and the problem of consistency of cache data of the cluster is solved.

Description

technical field [0001] The present invention relates to the technical field of data cache services, in particular to a cluster cache sharing method, system, device and storage medium. Background technique [0002] Commonly used caches in the field of back-end services are generally divided into two types, direct memory caches within services and third-party external caches. Internal cache frameworks currently include Guava, MapDB, etc. External caches such as Redis and Memcache. Among them, Guava is an open source Java library for providing caching functions. MapDB is an embedded java database engine that mainly provides data storage in the form of Map and set. Redis (Remote Dictionary Server, Remote Dictionary Service) is an open source log-type, Key-Value database written in ANSI C language, supporting the network, memory-based and persistent. Memcache is a distributed cache system. [0003] In the case of a single machine, frameworks such as Guava can manage cached d...
