How to Safely Add a New Column to a Production Database

A new column seems simple. It rarely is. Adding it in a production database means touching schema, migrations, code, tests, and possibly data backfills. In systems with high traffic and zero downtime requirements, a careless change can lock tables, block writes, or break deployment pipelines. The cost of mistakes can
