How to Safely Add a New Column to a Production Database

Adding a new column should be simple, but in production it often isn’t. Schema changes can break deployments, lock tables, or stall writes. The risk grows with scale. Downtime is expensive, and rolling back schema mistakes can be worse. That’s why controlled, versioned migrations are not optional. A
