In another comment, someone compared the PUB/SUB feature of Redis to ZeroMQ. Can the PUB/SUB feature of Redis function as a queue system for many common uses, or is there another significant difference that sets a full queue implementation apart? I ask because I am not particularly familiar with Redis, my queue usage has been fairly simple so far and I would enjoy simplifying my technology stack by combining the two if it makes sense.
