How does this skill help with zero-downtime deployments?

It provides specific 'expand-contract' patterns that allow the application to transition between schema versions gradually, ensuring compatibility while the database and code are updated in phases.

Does it work with modern TypeScript ORMs?

Yes, it includes detailed workflows and best practices for popular ORMs like Prisma and Drizzle, including how to handle manual SQL for operations the ORMs can't natively express.

Which database engines are supported?

While many principles apply universally, the skill provides specific, optimized SQL patterns and best practices for PostgreSQL and MySQL.

How does it handle large-scale data migrations?

The skill suggests batch-based update patterns and background backfill strategies to prevent long-running transactions from locking tables and causing application timeouts.
