Python & FastAPI•Part 5: ORMs, Databases & Background Workers (56 - 65)

Alternatives to Celery (ARQ, Dramatiq):

In Simple Words:

  • ARQ: Ultra-fast asynchronous task queue built on Redis and AsyncIO; ideal for FastAPI.
  • Dramatiq: Simpler, thread-based alternative to Celery with superior out-of-the-box retry logic and RabbitMQ/Redis backends.
python
# ARQ task definition:
async def download_file(ctx, url: str):
    async with httpx.AsyncClient() as client:
        resp = await client.get(url)
    return len(resp.content)
