What is a Redis cluster?

Redis cluster is a distributed database architecture that enables users to store and process data across multiple servers. By distributing data across multiple nodes, Redis cluster can improve system robustness and performance, while also scaling the database’s storage capacity and processing power.

A Redis cluster typically consists of multiple nodes, with each node responsible for storing and processing a portion of the data. The cluster uses a consistent hashing algorithm to determine where data is stored on which node, and implements data backup and fault tolerance through master-slave replication. In the event of a node failure, the cluster can automatically perform failover to ensure the stability and reliability of the system.

By utilizing Redis cluster, users can easily scale the size of their databases, improve system performance and availability to meet the growing demands of data processing. Additionally, Redis cluster provides a wealth of features and tools to help users manage and monitor the operational status of distributed databases, ensuring stable system operation.
