Class RedissonBlockingQueue<V>

All Implemented Interfaces:
Iterable<V>, Collection<V>, BlockingQueue<V>, List<V>, Queue<V>, RandomAccess, RBlockingQueue<V>, RBlockingQueueAsync<V>, RCollectionAsync<V>, RExpirable, RExpirableAsync, RList<V>, RListAsync<V>, RObject, RObjectAsync, RQueue<V>, RQueueAsync<V>, RSortable<List<V>>, RSortableAsync<List<V>>

public class RedissonBlockingQueue<V> extends RedissonQueue<V> implements RBlockingQueue<V>

Distributed and concurrent implementation of BlockingQueue.

Queue size limited by Redis server memory amount. This is why remainingCapacity() always returns Integer.MAX_VALUE
