I have some python code that I am refactoring, I can see that the tables have a column called "my_column" with a data type integer. Does this automatically get created?
Also is there a way I can explicitly set the data type of "my_column" to BigInt?

UniqueConstraintis separate from the table columns and doesn't have a data type. In your example there should be a separateColumn()named"my_column".The unique constraint is only created when doing something like
Base.metadata.create_all(engine)or via a migration using something like alembic.To alter an existing table you could use something like alembic to create a migration that would only be run once to change a column's datatype.
