lightweight database migration tool for SQLAlchemy
Alembic is a new database migration tool, written by the author of SQLAlchemy. A migration tool offers the following functionality:
- Can emit ALTER statements to a database in order to change the
structure of tables and other constructs * Provides a system whereby "migration scripts" may be constructed; each script indicates a particular series of steps that can "upgrade" a target database to a new version, and optionally a series of steps that can "downgrade" similarly, doing the same steps in reverse. * Allows the scripts to execute in some sequential manner.
