Use Queues to decouple producers from asynchronous consumers and buffer bursts of work. Design consumers for duplicate delivery; use Workflows when the task needs durable multi-step orchestration.

Fetch the relevant documentation below before implementing. Treat current Cloudflare docs as the source of truth for API signatures, acknowledgement semantics, configuration, limits, and pricing.

Choose a consumer

Use a Worker push consumer when processing runs on Workers.
Use an HTTP pull consumer when processing runs in another environment; plan for polling, visibility timeouts, and acknowledgement leases.
Choose a message encoding the consumer can decode. Check serialization and compatibility-date behavior before sending existing application objects.

See How Queues works and delivery guarantees before choosing ordering or deduplication strategies.
