Detailed description:

Redis is an open source, memory-based high-performance key-value storage system. It stores data in memory, providing very fast read and write access. Because the data is stored in memory, Redis can perform faster than traditional relational databases such as MySQL.

The main features of Redis include:

• High performance: It can handle millions of requests per second.
• Low latency: It provides very low latency, usually at the millisecond level.
• High Availability: Through replication and clustering, it ensures data redundancy and availability.
• Multiple data structures: It supports a variety of data structures, including strings, lists, hashes and sets.

Redis is widely used in a variety of applications, including:

• Cache: Stores frequently accessed data for faster access.
• Message queue: Realize message delivery and asynchronous processing.
• Session Management: Store user session data to track login status.
• Ranking list: Store and manage rankings.
