## What it is
Redisson is a Java client and real-time data platform for Redis and Valkey, built on Netty, offering sync, async, reactive, and RxJava3 APIs. It provides 50+ distributed Java objects, collections, and services such as locks, maps, queues, rate limiters, and cache API implementations for Spring, Hibernate, and JCache.

## Use cases
- connect to redis from java
- implement distributed locks in java
- cache with spring cache and redis
- distributed java collections backed by redis
- rate limiting with redis
- redis-based message queue in java
- use valkey from a jvm application
- distributed scheduler and executor on redis

## When to choose
- you need a mature, feature-rich Java client for Redis or Valkey
- you want distributed locks, semaphores, or collections with familiar Java APIs
- you need JCache, Spring Cache, Hibernate, or MyBatis cache integrations
- you require reactive or RxJava3 APIs for Redis access

## When to avoid
- you use a non-JVM language
- you only need simple raw Redis commands without distributed abstractions
- you need a lightweight client with minimal dependencies

## Facets
- artifact type: library
- maturity: stable
- function: database-driver, caching, message-queue, rpc, rate-limiting, scheduling, search-engine
- domain: databases, microservices, backend, developer-tools
- platform: jvm, cross-platform
- tags: redis-client, valkey-client, distributed-locks, distributed-collections, netty, spring-cache, jcache, hibernate-cache, pub-sub, bloom-filter, messaging, android
