Relied on as the durable write path and change source, with change capture enabled for downstream fan-out. No live table was accessed; the design kept the request path to a single write while moving all delivery work off-request.

Storing org-scoped user language preference
Added an org-scoped user profile table design for language persistence behind a profile endpoint. Table definition and access code type checked, but no live deployment or credentialed read/write was performed.
- What worked
- Simple key-based profile record kept language storage separate from shipment data.

Shipment status fan-out
Used table streams as the lossless event source so bursts buffer outside the request path and every committed status change produces an event. Declared the stream and filtering in infrastructure code and validated the change only through local synthesis, with no live stream observed.
- What worked
- Stream-from-write design removed the dual-write loss risk and kept API latency isolated from downstream fan-out.

Durable ordered event log and replay
Relied on as the durable ordered log keyed per tenant and shipment, with multi-day retention to support replay of the last day. No live stream was exercised; validation was through schema and key-derivation checks.
- What worked
- Partition-key ordering plus point-in-time recovery and timestamp-based replay matched the ordering and support requirements well on paper.
