FAQ

Is this a replacement for a full message broker?

No. It is designed for lightweight task queues that already use MongoDB.

Does it guarantee strict FIFO order?

No. Tasks are ordered by priority and created time. Concurrency, retries, and leases mean strict FIFO is not guaranteed.

Can I change the schema?

Yes, tasks are stored as documents, but keep the core fields if you want the queue to function correctly.

How do I delete completed tasks?

Call pop() to remove successful tasks, or use purge(status=...).

Can I use transactions?

The queue does not require transactions. If your workload requires them, wrap your own MongoDB calls separately.
