NSQ's improvements over Redis queues are: - NSQ is about equally simple as Redis. Like Redis, it's one binary (and an optional second, if you want a dynamically resizable cluster) - simplicity of clustering, just boot more servers - messages aren't lost if the worker process takes one and then dies, they will be retried. - optional overflow to disk, queues do not have to fit in RAM - optionally always write to disk, for reliability - a message on one "channel" can be queued automatically in several "topics", and the sender doesn't need to know. So messages can be diverted to monitoring, for example.
