Jan 1, 2025Month 2025-01 — Focused on boosting observability, data freshness, and performance for 1024pix/pix. Key work included introducing Datadog metrics for PGBoss job processing with histogram support and refactoring JobQueue to use a Metrics instance for precise execution-time tracking, enabling bottleneck identification and data-driven optimization. Implemented caching strategy and route configuration enhancements across API endpoints: disabled cache headers on data-sensitive endpoints to ensure freshness; aligned Hapi route configuration with v17+ to support explicit cache headers; and enabled Baleen caching for a targeted resource to reduce load. These changes collectively improve reliability, reduce stale data, and empower faster troubleshooting and capacity planning.
