Ooof. I don't mind the OSS/pro feature gate for the most part, but I really don't love that "Pro version uses smarter heartbeats to track producer liveness."
There's a difference between QoL features and reliability functions; to me, at least, that means that I can't justify trying to adopt it in my OSS projects. It's too bad, too, because this looks otherwise fantastic.
With a typical Redis or RabbitMQ backed durable queue you’re not guaranteed to get the job back at all after an unexpected shutdown. That quote is also a little incorrect—producer liveness is tracked the same way, it’s purely how “orphaned” jobs are rescued that is different.
