Union of the Snake
summary
A BEAM-inspired Oban implementation for Python is built from scratch, not a wrapper, recreating Oban semantics with TOML config, raw SQL queries, a CLI worker process to avoid the GIL, and async loopers that mimic GenServer behavior but lack true monitors and restart strategies. Cross-process notifications use a Postgres-backed shared jobs table and PubSub so Elixir and Python can enqueue each other. Tests run slower (Python Postgres suite 7.8s vs Elixir 3.4s). It works broadly but is Postgres-only and relies on Pro for process pools.
