Python Background Jobs

About

This skill provides comprehensive guidance and architectural patterns for implementing background workers and task queues in Python, enabling developers to decouple heavy lifting from the main request/response cycle. It covers essential distributed system concepts like task idempotency, job state machines, and dead letter queues using popular frameworks like Celery, RQ, and Dramatiq, ensuring Python applications remain responsive and resilient even when handling high-latency tasks or unreliable external services.

Key Features
