Node.js Service for Scanned Claims Intake: Async Jobs and Latency (Fidelity First)
Short answer: make the Node.js intake path durable and boring: accept a bounded upload, validate it before enqueueing, move bytes into a private temporary area, and let workers render or merge bundles asynchronously. Under load, protect the queue and the renderer separately. For marketplace claims, preserve the original scan as the source of truth; spend render cost only when a reviewer or…
The Node.js service for scanned claims intake should focus on durability and efficiency. Accept a bounded upload, validate it before enqueueing, move bytes into a private temporary area, and let workers render or merge bundles asynchronously. Protect the queue and renderer separately under load. Preserve the original scan as the source of truth for marketplace claims, spending render cost only when necessary.
Maintain invariants such as immutable original bytes, recorded digests, idempotent job handling, and clear transitions. Separate queues by failure domain, with the intake queue remaining responsive under high load, the render queue having a smaller concurrency limit, and a dedicated notification queue. Implement using a separate file for temporary storage, calculate SHA-256 digests, and store claim transitions with attempt counts and timestamps.
