register_operation

classmethod register_operation(name: str, sourcename: Optional[str] = None) → Callable

This method is normally used to add new operations to the Operations class, and possibly the BatchOperations class as well. All Alembic migration operations are implemented via this system, however the system is also available as a public API to facilitate adding custom operations.
