Lettuce is a scalable, thread-safe Redis client for Java built on Netty, supporting synchronous, asynchronous, and reactive APIs. It provides advanced Redis features including Cluster, Sentinel, pipelining, auto-reconnect, SSL, and pluggable codecs.

Use cases

• connect to redis from a java application
• use redis cluster with automatic topology discovery in java
• reactive redis streams with project reactor
• high-throughput redis pipelining from multiple threads
• failover to redis sentinel from a spring service
• serialize java objects to redis with custom codecs
• connect to aws elasticache or azure redis cache from jvm

When to choose

• you need a thread-safe Redis client sharing one connection across threads
• you require reactive or async Redis access on the JVM
• your deployment uses Redis Cluster or Sentinel
• you want the default client behind Spring Data Redis

When to avoid

• you need a simple blocking-only client and prefer a lighter API like Jedis
• your project is not on the JVM
• you rely heavily on blocking commands from shared connections, which Lettuce discourages
