##Redisson - distributed and scalable Java data structures on top of Redis server. Advanced Redis client

Use familiar Java data structures with power of Redis.

Based on patched version of lettuce Redis client and Netty 4 framework.
Redis 2.6+ and JDK 1.6+ compatible

Features

  • Cluster servers mode:
    1. automatic master discovery
    2. automatic new master server discovery
    3. automatic slots change discovery
  • Sentinel servers mode:
    1. automatic master and slave servers discovery
    2. automatic new master server discovery
    3. automatic new slave servers discovery
    4. automatic slave servers offline/online discovery
    5. read data using slave servers, write data using master server
  • Master with Slave servers mode: read data using slave servers, write data using master server
  • Single server mode: read and write data using single server
  • Distributed implementation of java.util.List
  • Distributed implementation of java.util.Set
  • Distributed implementation of java.util.SortedSet
  • Distributed implementation of java.util.Queue
  • Distributed implementation of java.util.concurrent.BlockingQueue
  • Distributed implementation of java.util.Deque
  • Distributed implementation of java.util.Map
  • Distributed implementation of java.util.concurrent.ConcurrentMap
  • Distributed implementation of reentrant java.util.concurrent.locks.Lock with TTL support
  • Distributed alternative to the java.util.concurrent.atomic.AtomicLong
  • Distributed alternative to the java.util.concurrent.CountDownLatch
  • Distributed publish/subscribe messaging via org.redisson.core.RTopic
  • Distributed HyperLogLog via org.redisson.core.RHyperLogLog
  • Thread-safe implementation
  • Supports OSGi
  • With over 110 unit tests
