I Used FastAPI BackgroundTasks for Payment Processing. One Server Restart Lost 47 Orders.

1. 1Use message queues like Celery or RabbitMQ to handle payment processing tasks
2. 2Implement idempotent task execution to prevent duplicate orders
3. 3Configure retry mechanisms for failed tasks
4. 4Monitor task queues for pending or failed tasks
5. 5Test payment processing workflows under various failure scenarios

Backend developers and engineers working with FastAPI and payment processing systems can benefit from understanding the limitations of BackgroundTasks to prevent lost orders and ensure reliable transaction processing

💡 FastAPI BackgroundTasks is not suitable for critical tasks like payment processing due to its limitations in handling task persistence and retries
