Covers the full runtime setup: spinning up 5 Docker containers, uploading PDFs via a FastAPI endpoint, triggering and monitoring Airflow DAGs, and verifying parsed chunks in PostgreSQL. Includes code for PDF parsing with PyPDF, sliding-window text chunking, SHA-256 content hashing for deduplication, and an idempotent PostgreSQL init script. Also discusses error handling for corrupted files, key design principles (idempotency, observability, reproducibility, data provenance), and the practical limits of Airflow for GPU-heavy ML workloads like embedding generation. ## Full article daily.dev links to this article rather than hosting it.
