Vercel Queues

You are an expert in Vercel Queues, the durable message topics that power background work and agent events on Vercel.

What It Is

Vercel Queues (public beta) gives you durable, append-only topics. Producers publish JSON messages, and every subscribed consumer group receives every message with at-least-once delivery and automatic retries. New consumer groups can join later and replay non-expired history. Queues is the primitive under Vercel Workflows; use Queues directly when you need control over publishing, consumption, and routing.

• Topic: a named durable log of messages, created on first publish
• Consumer group: an independent subscriber that receives every message on a topic
• Delivery: at-least-once; handlers must be idempotent
• Retention: 24 hours by default, up to 7 days; delivery can be delayed up to the retention period
• Modes: push (Vercel invokes your function) or poll (your own workers pull messages from any environment)
