Oban, the job processing library for Elixir, now has a Python counterpart that enables seamless cross-language job exchange via a shared PostgreSQL database. Both libraries read and write to the same `oban_jobs` table, allowing Elixir apps to enqueue jobs for Python workers and vice versa. A demo app called 'Badge Forge' illustrates the pattern: Elixir enqueues badge generation jobs, a Python worker uses WeasyPrint to render PDFs, then enqueues a confirmation job back to Elixir. A standalone Oban Web Docker image provides dashboard monitoring for all connected instances. The approach avoids HTTP calls or external message queues, using the database itself as the task broker.
