When I was deciding on a queuing system for the product I'm writing, after seeing the price of running a Kafka cluster on Digital Ocean and others, I opted for polling in postgresql and have been quite satisfied with its work so far (6ish months running). I have some improvements I need to make to the queue listener (right now, all the workers poll until there's work, when I could have it back off to 1); but otherwise it's plenty good enough. I'm really surprised at the price of Kafka clusters, to be honest. Hundreds of dollars per month extra at minimum.
