Hi,

Is there a way to make alembic commit all DDL and data changes completely
and begin a new transaction for each script?

Suppose I was upgrading and there were 3 migration scripts that needed
to run.  Suppose 2 of them passed, but the 3rd had a bug in the SQL and failed.
It would be nice if alembic's alembic_version would contain the
result of the 2 succeeding migrations.

sure thing:

Thanks,
