We use in live environment for about 3 years. We didn't had any incident with it. Persistence is a file, that you can backup regularly to a secondary storage.

- We have on peek 10k OPs/second.

- features we like is priority, TTR, pause tube (while deploying new code)

- responds really fast to stats (we have on a Stats/Graphite dashboard)

We love the Beanstalkd Admin Console panel. https://github.com/ptrofimov/beanstalk_console

I haven't tried it actually. I evaluated it a few years ago and I remember that the queue persistance was missing (though now I see it is supported), and it lacked handling retries out of the box (which Gearman does).

Now I've wrote my own wrapper to handle retries on the client side so I might give it a try.
