How to handle database migration scripts in Tornado framework.?

I have been searching for libraries that can handle database migration for tornado framework. How is the database migration handled in Tornado framework ?

I was working on Yii Framework before and it has a very convenient CLI tool to handle Database migration.

I am looking for something like that.

Solution

I highly recommend Alembic. It was originally written to support SQLAlchemy, but you don't need to use SQLAlchemy as long you have a relational database it supports. That said, you will need to understand SQLAlchemy Core to work with Alembic, but that is generally a useful skill to have.
