Graceful Shutdown and Backpressure #36
Description
Why
Prevent data loss and keep service stable under load.
Definition of Done
- Server drains in‑flight requests on shutdown.
- Background workers stop polling and finish running jobs.
- Queue length and worker concurrency are bounded and configurable.
- Load test shows stable latency under sustained pressure.
Tasks
- Wire shutdown signals to server and workers.
- Add bounded channels for job dispatch.
- Expose configuration for concurrency and queue sizes.
- Create a simple load script and record results.
