RedissonClient redisson = Redisson.create(config);

// Reactive API
RedissonReactiveClient redissonReactive = Redisson.createReactive(config);

// RxJava2 API
RedissonRxClient redissonRx = Redisson.createRx(config);
// 3. Get Redis based Map
RMap<MyKey, MyValue> map = redisson.getMap("myMap");

RMapReactive<MyKey, MyValue> mapReactive = redissonReactive.getMap("myMap");

RMapRx<MyKey, MyValue> mapRx = redissonRx.getMap("myMap");
// 4. Get Redis based Lock
RLock lock = redisson.getLock("myLock");

RLockReactive lockReactive = redissonReactive.getLock("myLock");

RLockRx lockRx = redissonRx.getLock("myLock");
// 4. Get Redis based ExecutorService
RExecutorService executor = redisson.getExecutorService("myExecutorService");

// over 30 different Redis based objects and services ...
