backend-migrations

功能与用途

Create and manage database migrations with reversible up/down methods, zero-downtime deployment strategies, and proper schema versioning. Use this skill when creating database migration files, altering table schemas, adding or modifying database indexes, or implementing data migrations. Use when working with migration tools like TypeORM migrations, Sequelize migrations, Alembic (Python), Rails migrations, Flyway, or Liquibase. Use when writing migration files (e.g., YYYYMMDDHHMMSS_migration_name.ts, 001_create_table.sql, versions/*.py) or when modifying database schema in a version-controlled manner. Use when handling backwards compatibility for high-availability deployments or when separating schema changes from data migrations.
