Issue: Investigate Checkout Service operational risk 19

ID: GH-2019 Date: 2026-04-26 Repository: acme-commerce/checkout-service Service: Checkout Service Owner: Commerce Platform Status: open Type: issue

Summary

This issue tracks production-readiness work for the Checkout Service. The concern is related to connection pool saturation during a regional traffic burst. The implementation area touches API contracts API-CHECKOUT-01, API-CHECKOUT-02, service telemetry, and operational runbooks.

Engineering Notes

  • Validate that retries are bounded and idempotency keys are respected.
  • Add structured logs with service, correlation_id, and customer_impact fields.
  • Confirm dashboards show p95 latency, error rate, dependency saturation, and queue depth.
  • Cross-service impact should be reviewed with Checkout Service, Billing Service, Inventory Service, Authentication Service, and Notification Service owners when applicable.

Acceptance Criteria

  1. Contract tests cover expected and malformed payloads.
  2. Runbook references are updated for Checkout Service.
  3. The change can be linked from Jira remediation tickets and incident reviews.
