Celery: Offloading Work from Your FastAPI App
Celery lets your web app offload slow tasks to a separate process, keeping your API responsive. Use it for tasks that can't finish in a single HTTP request, like sending bulk emails or processing images.
Celery lets your web app offload slow tasks to a separate process, preventing blocked requests and keeping your API responsive. Think of it as a dedicated workforce for your app's heavy lifting. It's vital for tasks that shouldn't make a user wait, like sending bulk emails, processing large PDFs, or running ML models. The footgun: assuming your app and Celery talk directly. You must configure a message broker (like Redis or RabbitMQ) to queue tasks and a results backend to store outcomes.
