##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 2.4+ and JDK 1.6+ compatible

####Simple config example
// connects to Redis server 127.0.0.1:6379 by default
Redisson redisson = Redisson.create();
...
redisson.shutdown();
or with initialization by Config object
Config config = new Config();
config.setConnectionPoolSize(10);
// Redisson will use load balance connections between listed servers
config.addAddress("first.redisserver.com:8291");
config.addAddress("second.redisserver.com:8291");
config.addAddress("third.redisserver.com:8291");
Redisson redisson = Redisson.create(config);
...
redisson.shutdown();
####Distributed Map example
Redisson redisson = Redisson.create();
ConcurrentMap<String, SomeObject> map = redisson.getMap("anyMap");
map.put("123", new SomeObject());
map.putIfAbsent("323", new SomeObject());
map.remove("123");
...
redisson.shutdown();
####Distributed Set example
Redisson redisson = Redisson.create();
Set<SomeObject> set = redisson.getSet("anySet");
set.add(new SomeObject());
set.remove(new SomeObject());
...
redisson.shutdown();
####Distributed List example
Redisson redisson = Redisson.create();
List<SomeObject> list = redisson.getList("anyList");
list.add(new SomeObject());
list.get(0);
list.remove(new SomeObject());
...
redisson.shutdown();
####Distributed Queue example
Redisson redisson = Redisson.create();
Queue<SomeObject> queue = redisson.getQueue("anyQueue");
queue.add(new SomeObject());
queue.peek();
queue.pool();
...
redisson.shutdown();
####Distributed Lock example
Redisson redisson = Redisson.create();
Lock lock = redisson.getLock("anyLock");
lock.lock();
lock.unlock();
// same as
redisson.getLock("anyLock").lock();
...
redisson.getLock("anyLock").unlock();
...
redisson.shutdown();
####Distributed AtomicLong example
Redisson redisson = Redisson.create();
RAtomicLong atomicLong = redisson.getAtomicLong("anyAtomicLong");
atomicLong.set(3);
atomicLong.incrementAndGet();
atomicLong.get();
...
redisson.shutdown();
####Distributed CountDownLatch example
Redisson redisson = Redisson.create();
RCountDownLatch latch = redisson.getCountDownLatch("anyCountDownLatch");
latch.trySetCount(1);
latch.await();
// in other thread or other JVM
RCountDownLatch latch = redisson.getCountDownLatch("anyCountDownLatch");
latch.countDown();
...
redisson.shutdown();
####Distributed Topic example
Redisson redisson = Redisson.create();
RTopic<SomeObject> topic = redisson.getTopic("anyTopic");
topic.addListener(new MessageListener<SomeObject>() {
public void onMessage(SomeObject message) {
...
}
});
// in other thread or other JVM
RTopic<SomeObject> topic = redisson.getTopic("anyTopic");
topic.publish(new SomeObject());
...
redisson.shutdown();
