Schema Migrations Are Silently Breaking Your ML Models. Synthetic Databases Can Catch It First.

Designed using LLM Every time your database schema changes, your ML pipeline is at risk. Here is how to use synthetic data generation to test migrations before they reach production features. The most expensive ML bug I have ever debugged cost four days and was caused by a column rename. A backend engineer renamed user_created_at to account_registration_date in a migration. It was a clean rename, well-intentioned, documented in the migration log. The database team ran it on a Friday. The ML pipeline ran on Saturday morning. It did not crash. It did not throw an exception.
