Redis universal agent-based implementation method, storage medium and electronic equipment

Abstract

The invention provides a Redis universal agent-based implementation method. The method comprises the following steps of configuring the connection of a Redis universal agent, connecting the Redis universal agent with a Redis Sentinel, acquiring a Master instance through a Sentinel Masters command, recording the Master instance into a set Masters, traversing the set Masters to obtain a Slave instance associated with the Master instance through a Sentinel Slaves command, distributing the Master instance and the Slave instance by adopting the consistency hash algorithm, subscribing the switch-master information through a Redis Sentinel PSUBSCRIBE command, calling a Redis proxy interface by a client, creating a proxy connection handle, and executing a Redis command through the connection proxyhandle. According to the invention, the relation between the Master instance and the Slave instance is recorded through the connection configuration of the Redis universal proxy. Meanwhile, the Master instance and the Slave instance are distributed by adopting the consistency hash algorithm. Therefore, the distribution of a key in a cluster can be managed in a consistent hash mode. Moreover, distribution uniformity among all instances can be guaranteed.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a Redis-based universal proxy implementation method, storage medium and electronic equipment. Background technique [0002] Redis is an open source, high-performance key-value storage (key-value store) system. All key values ​​of Redis are stored in memory, which has high single-machine read and write performance. When operating Redis, it is necessary to communicate with the Redis server according to the Redis protocol specification. Redis has provided the sentinel function since version 2.8. When Redis is configured with master-slave mode, master-slave switching can be performed through sentinel. [0003] In the existing technology, Redis has the following problems: Redis commands cannot span multiple Redis instances, and the same operation may operate multiple keys. The existing Redis client cannot guarantee that multiple keys are on the same Redis instance. Operations...
