Month 2025-11: Focused on server reliability and maintainability for potiuk/airflow. Implemented a robust uvicorn health check timeout configuration, aligning worker health checks with existing timeouts to improve stability under load. This work ensures long-running workers are less likely to be incorrectly marked healthy, reducing false positives and outages in production. Key features and outcomes: - Implemented Server Reliability Improvement: Uvicorn Health Check Timeout Configuration for potiuk/airflow. Increased default health check timeout from 5 seconds to 120 seconds by configuring timeout_worker_healthcheck in uvicorn_kwargs, and aligned with existing timeout_keep_alive and timeout_graceful_shutdown. - Enforced minimum uvicorn version 0.37.0 to enable the new setting, ensuring compatibility and future-proofing configuration. - Wired timeout_worker_healthcheck to the worker_timeout value, ensuring consistency across health checks and keep-alive mechanisms. - Documentation and traceability through commit e98dd9ff7dfb5bc56c58819f9cafaf195e52b964 and PR #57731. Impact and value: - Higher reliability and fewer false-negative health signals during load, reducing outages and manual intervention needs in production. - Improved resilience for long-running workers and safer deployments during traffic spikes. Technologies and skills demonstrated: - Python/uvicorn configuration, version pinning, and CLI-driven timeout management. - Integration of health-check timeouts with existing keep-alive/graceful shutdown controls. - Change traceability with commit-level details and PR linkage.
