What are the semantics of proper “priority queues”? As far as I know, both Sidekiq and Faktory have two modes, the weighted mode, and then a mode where all of queueA will be processed before moving on to queueB, i.e. it inherits the semantics of BRPOP.
I didn’t know that Pro uses MBRPOPLPUSH. We use a our own version of Faktory that uses Redis scripts to give us better guarantees.
