        $this->queueName = $queueName;
        $this->queueKey = "queue:".$queueName;

    }

    public function getSize()
    {
        return $this->client->llen($this->queueKey);
    }

    public function push($element)
    {
        $this->client->lpush($this->queueKey,$element);
    }

    public function pop()
    {
        return $this->client->brpop([$this->queueKey],$this->timeout);
    }
