Problems solved by technology

[0003] However, the Redis cluster built by Twemproxy and Redis Sentinel belongs to the centralized management architecture. Redis Sentinel is prone to abnormalities, and Redis Sentinel plays an important role in ensuring the high availability of Redis clusters. Once the service is abnormal, the transfer of Redis storage fragmentation failures will fail. Automatic completion requires manual operation and maintenance intervention, data integrity and high availability of the Redis cluster cannot be guaranteed

Embodiment approach

[0088] In addition, as another implementation mode, it can also be selected as:

[0089] When a data access request is detected, determine the data key value in the data access request;

[0090] Obtain the number of data partitions by the Redis cluster agent component, and use the data key value to take the modulus of the number of data partitions to obtain a modulus result;

[0091] Determine the non-downtime target data partition according to the modulus result.

[0092]Specifically, obtain the number of data partitions contained in the Redis cluster management device through the Redis cluster agent component, that is, the number of data partitions, and use the data key value to take the modulus of the number of data partitions to obtain the modulo result (remainder) , and then obtain the preset mapping relationship table between the modulus result and the data partition, query the mapping relation table, obtain the data partition corresponding to the modulus result, and ju...

Abstract

The invention discloses a Redis cluster management method, which comprises the following steps of: when a data access request is monitored, determining a target data partition which is not downtime through a Redis cluster agent component and a data key value in the data access request; routing the data access request to the target data partition, and processing the data key value to obtain a hashslot number; and routing the data access request to a Redis node corresponding to the hash slot number in the target data partition. The invention also discloses a Redis cluster management device, equipment and a readable storage medium. According to the invention, the data integrity and high availability of the Redis cluster can be effectively ensured.

Description

technical field [0001] The present invention relates to the technical field of Redis clusters, in particular to a Redis cluster management method, device, equipment and readable storage medium. Background technique [0002] Due to the limited memory management capability of a single Redis server, a failure of the Redis server will directly affect a large area of ​​business. In order to obtain better cache performance and scalability, a Redis cluster is built to meet the requirements. At present, Redis clusters are built mainly through Twemproxy and Redis Sentinel, that is, Twemproxy is a single-threaded proxy program that supports the Redis protocol. By introducing a proxy layer, it encapsulates the real Redis storage fragmentation at the back end, and implements Failover through RedisSentinel to ensure Redis storage fragmentation. High availability of slices. [0003] However, the Redis cluster built by Twemproxy and Redis Sentinel belongs to the centralized management ar...
