Vercel Queues is a durable event streaming system built on Fluid compute, now available in public beta for all teams.
- •Messages are published to durable topics and fanned out to subscribed consumer groups, each processing independently
- •Provides at-least-once delivery semantics with automatic retries until messages are successfully processed or expired
- •Publishers use the `send` function and consumers use `handleCallback` from the `@vercel/queue` package via route handlers
- •Consumer routes are made private through `vercel.json` trigger configuration, invocable only by Vercel's queue infrastructure
- •Billed at $0.60 per 1M operations, including multi-AZ replication, delayed delivery, idempotency keys, and concurrency control
