Events

Producers write event_outbox in the same database transaction as the business change. outbox-relay-service publishes the envelope to Redis Streams. Consumers append to inbox_messages and let InboxMessageWorker run the handler. Handlers must be idempotent on event_id.

Produced​

  • No transactional outbox. Upload completion is synchronous HTTP plus object storage.

Consumed​

  • No Redis stream consumers. Redis is a cache and rate-limit store.

Envelope fields that matter for operations: eventId, type, traceId (from X-Request-Id). See request correlation.
