Redis use cases

Redis (Remote Dictionary Server) is an in-memory, NoSQL database known for its high performance and versatility. It functions primarily as an in-memory data store but also supports persistence mechanisms like RDB and AOF^[600-developer-redis.md]. It utilizes a Reactor pattern with epoll for I/O event notification^[600-developer-redis.md].

Beyond acting as a database, Redis is widely adopted for several specific architectural roles:

  • Caching: Due to its speed and in-memory nature, it is frequently used as a cache to reduce database load and decrease latency^[600-developer-redis.md].
  • Message Broker: It serves as a lightweight message middleware (message middleware), enabling asynchronous communication between services^[600-developer-redis.md].
  • Database: It operates as a primary data store for use cases requiring rapid read/write operations^[600-developer-redis.md].

Redis supports a variety of data structures that enable these use cases, including strings, lists, sets, sorted sets (zset), and hashes^[600-developer-redis.md].
