Duty Job Queue

Duty is a simple job queue for Node.js that runs in-memory by default, requiring no external database for basic use. Version 2.5.1 is the latest stable; releases are infrequent. Key differentiators: dumb-simple API, database-agnostic via dbstream, supports progress events, timeouts, retries with backoff, and concurrency control. Lighter than Kue or Bull, no Redis needed for simple cases.
