Hello, I'm looking for way to a add new attribute to the compute nodes by adding a column to the compute_nodes table in nova database in order to track a metric on the compute nodes and use later it in nova-scheduler.
I checked the sqlalchemy/migrate_repo/versions and thought about adding my own upgrade then sync using nova-manage db sync. My question is : What is the process of upgrading a table in the database ? Do I have to modify or add a new variable in some class in order to associate the newly added column with a variable that I can use ? Best regards,
