> DB based queues are fine if you don't need more than a few messages a second of transport I'd estimate more like dozens to hundreds per second should be pretty doable, depending on payload, even on a small DB. More if you can logically partition the events. Have implemented such a queue and haven't gotten close to bottlenecking on it.
