What frameworks does this migration skill support?

It provides standardized patterns and examples for major frameworks including Python's Alembic, Ruby on Rails' ActiveRecord, and JavaScript's Sequelize.

Why are schema and data migrations separated?

Separating them ensures structural changes remain fast and predictable, while slower data transformations can be managed and rolled back independently without affecting the schema version.

Can it help with large-scale data updates?

Yes, the skill enforces batch processing and idempotency in data migrations to prevent memory issues and ensure scripts can be safely re-run if interrupted.

How does it handle zero-downtime deployments?

The skill guides a multi-step approach for breaking changes (like renaming columns) and uses concurrent indexing techniques to prevent table locks during schema updates.

소개

This skill provides Claude Code with a comprehensive framework for managing database evolution with extreme care and precision. It focuses on creating safe, reversible schema changes and data migrations that prevent service interruptions. By implementing best practices like concurrent index creation, idempotent data scripts, and multi-step column modifications, this skill ensures that database updates are production-ready across various environments and frameworks such as Alembic, Rails, and Sequelize.
