NSQ – A realtime distributed messaging platform
I'm glad these new projects are coming on, and this one seems to be very forthright about its limitations, but I'm just putting this in the bucket with all of the other messaging systems that provide a minimum feature set.I haven't seen much on the market recently that offers things like (first-class) persistence, guaranteed ordering, guaranteed delivery, or any of the other more complex distribution patterns. That's why I'm still using ActiveMQ.  I'm pretty happy with it, so I suppose I'm not really looking for a replacement, but I still wonder what benefit people are getting from these newer systems.
