## What it is
Oban is a robust background job processing library for Elixir, backed by PostgreSQL, SQLite3, and MySQL, with transactional job insertion, retries, scheduling, and observability. A commercial Oban Pro tier adds durable workflows, global concurrency, rate limiting, batches, and unique jobs, and the framework also ships a Python version.

## Use cases
- run background jobs in elixir backed by postgres
- schedule recurring cron jobs in my phoenix app
- enqueue jobs transactionally with database changes
- build durable multi-step workflows with dependencies
- retry failed jobs with error handling
- limit job concurrency across a cluster
- process background tasks without redis

## When to choose
- you already run a SQL database and want job queues without extra infrastructure like Redis
- you need transactional, at-least-once job execution with retries and historic job retention
- you want cron scheduling, queue control, and telemetry out of the box
- you need durable workflows, batches, or global concurrency and are open to a paid Pro license

## When to avoid
- you need a language other than Elixir or Python
- you want a broker-based queue decoupled from your primary database
- you need sub-second latency fire-and-forget messaging rather than durable job processing
- you require Pro features like workflows or unique jobs but cannot use a commercial license

## Facets
- artifact type: library
