OBAN - Robust job processing in Elixir, backed by modern PostgreSQL

Oban's primary goals are reliability, consistency and observability. It is fundamentally different from other background job processing tools because it retains job data for historic metrics and inspection. You can leave your application running indefinitely without worrying about jobs being lost or orphaned due to crashes.

Jobs are stored in a single table but are executed in distinct queues. Each queue runs in isolation, ensuring that a job in a single slow queue can't back up other faster queues. Queues can be started, stopped, paused, resumed and scaled independently at runtime locally or across all running nodes (even in environments like Heroku, without distributed Erlang).
