Live Migrations

gistfile1.txt

I just had my meeting with Henry in person. I have received clear (yet complicated) direction and tasking:

Ressurect https://review.openstack.org/#/c/99965/42 in neutron first and run with it for some time and make https://review.openstack.org/#/c/248190/ use it
Repropose it to oslo.db for citizenship in that project
Create the tests for neutron's migrations
My notes (in an unorganized manner):
Ressurect https://review.openstack.org/#/c/99965/42 in neutron first and run with it for some time
Then propose it to oslo.db
Can take out everything about downgrade

Move over the the oslo.db patch
Make 124946 dependent on the new patch
3: line (neutron patch)#542 (oslo.db)#693 def walk_versions
*: look into https://github.com/openstack/oslo.db/blob/master/oslo_db/sqlalchemy/test_base.py
