outbox capability

outbox adds the transactional outbox pattern to your Go service, guaranteeing events are published even when the process crashes between a database write and a message broker publish.

What You Get

Section titled “What You Get”
  • Outbox table
  • Publisher
  • Relay worker for at-least-once delivery

When to Use

Section titled “When to Use”

Without the outbox pattern, a crash between committing to the database and publishing to a message broker means the event is silently lost. Use outbox whenever events must be reliable — order placed, payment received, shipment dispatched.
