Youil
Yulit worked on backend stability and observability improvements in the potiuk/airflow and apache/airflow repositories over a two-month period. Using Python, FastAPI, and SQLAlchemy, Yulit implemented a session cleanup middleware for the FAB FastAPI app, ensuring SQLAlchemy sessions were properly removed after each request to prevent PendingRollbackError and idle transactions under WSGIMiddleware. In apache/airflow, Yulit addressed a crash in DagRun tracing by validating the OpenTelemetry context carrier, ensuring root span emission for legacy DagRuns and compliance with tracing specifications. The work focused on robust error handling, resource management, and enhancing the reliability of backend tracing and diagnostics.
