This is not a bug. This line is informational, and it means that Alembic will assume that the Data Definition Language (DDL) operations (e.g., creating tables, indices, etc.) will not be executed within a transaction. In other words, when Alembic applies migrations to the database, it will not wrap the DDL operations in a transaction. This means that if any of these operations fail, the database will not roll back to its previous state, and the migration process will continue.
By assuming non-transactional DDL, Alembic is allowing the database to execute these operations directly, without creating a transaction that could be rolled back. This is often the default behavior for many databases, as transactions are not always supported for DDL operations.
In general, this message is just an informational notification, and it doesn't require any specific action from you. Alembic is designed to handle these situations, and the migration will continue as usual.

thank's for your response, but the process seems stopped at this step and I don't have any other step started like below
INFO: Started server process [14860]
INFO: Waiting for application startup.
INFO: Application startup complete.
INFO: Uvicorn running on http://127.0.0.4:8084 (Press CTRL+C to quit)
This step don't appear
that's why http://127.0.0.4:8084 don't work !
