I'm not sure what you mean by unique jobs, but for scheduled jobs, it could definitely be on the roadmap. I'm still deciding whether or not its a good idea to make it more of an actual service than just a library.

Examples: https://github.com/noxdafox/rabbitmq-message-deduplication

https://nats.io/blog/new-per-subject-discard-policy/

So ensuring that each message has a unique payload?
