Async Task Queue With Retry And Error Handling

via “automatic retry and failure recovery with exponential backoff”

Python workflow orchestration — decorators for tasks/flows, retries, caching, scheduling.

Unique: Implements retry logic as a first-class concern in the task execution pipeline, with jitter-based exponential backoff to prevent thundering herd problems. Retries are composable with caching — a cached result bypasses retries entirely.

vs others: More flexible than Celery's retry mechanism (which is queue-specific) and simpler to configure than Airflow's SLA/retry operators, with built-in jitter to avoid cascading failures.
