Database Migrations
affaan-m/eccMaking changes to a live database can be risky. Database migrations let you update tables, columns, and indexes without breaking your application. You can also roll back changes if something goes wrong.
This guide covers best practices for PostgreSQL and MySQL. It also explains how to use popular ORM tools like Prisma, Django, and TypeORM. You will learn how to avoid downtime by using patterns like expand-contract and concurrent index creation.
Migrations should always be tested with production-sized data. Never edit a migration that has already run. Keep schema and data changes in separate steps. These simple rules keep your database reliable.
