How Python Data Engineers Use Amazon RDS

Python data engineers use RDS as the managed database backend for pipeline metadata stores, staging databases, and application databases. Engineers connect via standard Python database drivers (psycopg2, pymysql) or SQLAlchemy, using IAM authentication for credential-free access. RDS Proxy is used in Lambda-based ingestion functions to avoid connection pool exhaustion.
