Cloudflare Queues

Build reliable asynchronous message processing on Cloudflare Workers using Queues for background tasks, batch operations, and retry handling.

When to Use

• Background Tasks - Offload non-critical work from request handlers
• Batch Processing - Accumulate messages and process in batches to reduce upstream API calls
• Retry Handling - Automatic retries with configurable delays for transient failures
• Decoupling - Separate producers from consumers for scalability
• Rate Limiting Upstream - Control the rate of requests to external APIs
• Dead Letter Queues - Capture and inspect failed messages for debugging
