ephraimbuddy opened a new pull request, #62234:
URL: https://github.com/apache/airflow/pull/62234
The `--use-migration-files` flag was removed in #41120 when we pruned the
migration history for Airflow 3. At the time, we couldn't create a database
from scratch using only migration files because the migration chain no longer
started from an empty database. The oldest migration assumed an existing 2.6.2
schema.
Now that we have a squashed migration (0000_2_6_2) with `down_revision =
None` that creates the full baseline schema from scratch, we can re-introduce
this flag. This enables a critical development workflow, which is: creating the
database purely from migration files, then using `alembic revision
--autogenerate` to detect schema drift between the ORM models and the
migration-produced schema. Without this flag, `autogenerate` compares against
an ORM-created database (via `create_all`), which masks any drift since both
sides come from the same ORM definitions.
