Backend Migrations

概要

Streamlines the process of modifying database structures by providing expert guidance on creating, testing, and deploying schema changes. This skill helps developers implement reversible migrations, handle large-scale index creation safely, and maintain data integrity across various frameworks like Django, Rails, and Prisma. It is particularly useful for teams aiming for high-availability systems where backward compatibility and zero-downtime deployments are critical requirements for maintaining service continuity.
