Can it handle migrations between different database types?

Yes, it includes logic for handling dialect-specific differences, such as transitioning between PostgreSQL JSONB and MySQL JSON types.

How does it facilitate zero-downtime migrations?

It utilizes a multi-phase strategy involving backward-compatible schema changes, dual-writing data, and incremental backfilling to ensure no service interruption.

Is it suitable for large-scale data transformations?

It provides specific patterns for batching data updates and multi-step column renames to minimize table locking and performance impact on large datasets.

Which ORMs does this skill support?

The skill provides specialized patterns, code snippets, and best practices for Sequelize, TypeORM, and Prisma.

Does it include safety measures for failed migrations?

Yes, it emphasizes transaction-based migrations and checkpoint-based rollback strategies to ensure you can revert to a stable state if a migration fails.
