Alembic is a database migrations tool for SQLAlchemy.
|
|
|
|
* 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.
