Rohit, Just on note on: >>>Min, you’re right I don’t propose to change the IAM model just some >>>additional data that notes who *actually* owns the resource (VM, volume, >>>etc.) in an account which can be useful for sysadmins to list resource by >>>userid etc.
Adding 'user_id' column but not changing IAM model should be a small change and not causing any IAM side effects. But, it still won't really mean that that 'userid' 'owns' the resource. The ownership will still stay with the account - and so all other users in that account will still be able to access that resource, as per CS IAM. The userid will just provide an insight on which user in the account created the resource.

Mike: I don’t propose to use user name but uuids so they are unique. My concern was adding user_id column to say vm_instance table denormalizes data as that table already has domain_id and account_id in it and as Rajani suggested earlier those two are not needed as using user_id one can find account_id and domain_id. I guess, the easiest way would be to just add an additional user_id column.
