Alembic is a database schema migration tool for SQLAlchemy, supporting versioned migration scripts with upgrade/downgrade steps. It can autogenerate migrations by diffing the database schema against SQLAlchemy models and supports transactional DDL and offline SQL script generation.
Use cases
- manage database schema migrations for a SQLAlchemy project
- autogenerate migration scripts from changed ORM models
- upgrade and downgrade database schema versions
- generate SQL migration scripts for DBA review
- apply ALTER statements to evolve table structures
When to choose
- your application uses SQLAlchemy and needs versioned schema migrations
- you want autogenerated migrations from Python model changes
- you need transactional DDL support on PostgreSQL or SQL Server
When to avoid
- you use an ORM other than SQLAlchemy
- you need a database-agnostic migration tool without SQLAlchemy
- you only need simple schema setup without version tracking
