Alembic DB Migrations
These files are for creating/updating the tables in the Relational DB (Postgres). Danswer migrations use a generic single-database configuration with an async dbapi.
To generate new migrations:
run from danswer/backend:
alembic revision --autogenerate -m <DESCRIPTION_OF_MIGRATION>
More info can be found here: https://alembic.sqlalchemy.org/en/latest/autogenerate.html
Running migrations
To run all un-applied migrations:
alembic upgrade head
To undo migrations:
alembic downgrade -X
where X is the number of migrations you want to undo from the current state
