cloudflare-queues

Cloudflare Queues enable asynchronous processing by letting you create producer and consumer patterns using Wrangler CLI. Producers call send() or sendBatch() to publish messages; consumers implement queue handlers that process batches with explicit ack() and retry() controls, scaling automatically across Workers.

Yes, Cloudflare Queues supports explicit retry() logic with exponential backoff and dead-letter queue (DLQ) integration for failed messages. Configure max_batch_size, max_batch_timeout, and leverage message delays up to 12 hours to handle processing failures gracefully.

Messages in Cloudflare Queues are limited to 128 KB each. Maximum message delay is up to 12 hours, and the system handles batching and concurrency auto-scaling to meet latency requirements across your serverless environment.

Use Cloudflare Queues with Wrangler to decouple producers from consumers through asynchronous batching. Producers submit tasks via send() or sendBatch(); consumers process queue(batch) events, reducing bottlenecks and enabling independent scaling of workloads.

Cloudflare Queues is designed for scalable background processing on Cloudflare Workers. It decouples async workloads, supports batching with visibility controls, explicit acknowledgments, and integrates directly with the Wrangler/Workers ecosystem.
