Silent Exception Failures in ETL
A production ETL run lost 198 rows (0.0013% of 15.2M total) when asyncpg connection errors caused worker processes to crash silently without retry logic or exit code checking. Python's exception-based error handling made this vulnerability invisible—unlike Rust's Result<T, E> which forces explicit error handling at compile time, Python function signatures don't indicate what exceptions can be raised, making defensive programming entirely optional and prone to being overlooked.
