Build a durable order pipeline

Build a complete producer, route, worker, retry policy, and replay workflow for an order event.

Arc Runtime 3.xUpdated Jul 18, 2026

Model the event

Keep the event focused on a completed business fact. Avoid embedding commands or mutable workflow state in the payload.

fixtures/order-accepted.json

{
  "type": "order.accepted",
  "id": "evt_2F9Q",
  "payload": {
    "orderId": "ord_7K2M",
    "region": "north"
  }
}

arcwell.streams.yml

streams:
  northline-fulfillment:
    lease: 30s
    retries:
      attempts: 6
      backoff: exponential
      maximum: 15m

shell

arcctl quarantine list --stream northline-fulfillment
arcctl replay evt_2F9Q --reason "handler fix deployed"
