Maybe this doesn't matter. No, I don't think this matters much, to be honest. I'm not entirely sure what the long-term purpose of the shadow tables are in Nova -- perhaps someone could clue me in to whether the plan is to keep them around? As I know the tables shadow_* are used by command ' nova-manage db archive_deleted_rows' , which moves records with "deleted=True" to table shadow_* . That means these tables are used by other process, So, I think we need other tables to store the old records in your migration.Yeah, that's what I understood the shadow tables were used for, I just didn't know what the long-term future of these tables was... curious if there's been any discussion about that.

I think Joe Gordon was working on something in the hopes of eventually killing the shadow tables but I can't remember exactly what that was now.
