Chancy

A postgres-backed task queue for Python.

Key Features

• Fully-featured jobs support priorities, retries, timeouts, memory limits, future scheduling, and more.
• Completed jobs stick around in the database for easy debugging and job tracking, with configurable retention policies. Inspect your jobs with plain old SQL, an HTTP API, or the dashboard.
• Core is dependency-free except for psycopg3, but plugins can add additional dependencies.
• Optional transactional job queueing - only queue a job if your transaction commits successfully.
• asyncio-based worker, can be run in-process with your web server on small projects or as a standalone worker on larger projects.
• Statically declare your queues or create and manage them on-the-fly, assigning them to workers based on tags.
