Stopping Kafka mid-sync did not block clinical data persistence: the sync batch processor
|
|
applied the observation to PostgreSQL and left one outbox row pending (`processed_at IS NULL`).
|
|
When Kafka restarted, `OutboxRelayService` drained the backlog within 60 seconds
|
|
(outbox pending 1 → 0). This demonstrates the intended separation between Tier 1 durable
|
|
writes and Tier 2 async scoring pipelines — NEWS2 and downstream consumers may lag during
|
|
broker outages, but observations are not lost and replay correctly once Kafka is available.
