Description RHOS Integration 2013-12-12 19:16:11 UTC

Cloned from launchpad blueprint https://blueprints.launchpad.net/glance/+spec/convert-to-alembic.

Description:

Some work has already been started on moving from SQLAlchemy-migration to Alembic on other projects like ceilometer and nova and their blueprints can be located through the following links:

https://blueprints.launchpad.net/nova/+spec/convert-to-alembic

https://blueprints.launchpad.net/ceilometer/+spec/convert-to-alembic

Even though the above blueprints have enough info on this. Some of the notable points to plan to move from sqlalchemy-migration to alembic are:

1) sqlalchemy-migration project is no longer maintained and doesn't accept bug fixed any more.
For more info on the activity of the project, please visit:
http://code.google.com/p/sqlalchemy-migrate/
https://www.ohloh.net/p/sqlalchemy-migrate/commits/summary

2) does not support SQLAlchemy 0.8.x (but seems like some patches are available but not sure if it addresses all compatibility issues)
