I think Erik's looking for a timeframe for this, too. We could implement this tomorrow in Glance, but there's been a conscience decision to use URIs as an image's globally-unique identifier, and to allow Glance registries to implement whatever image ID they wanted. This can, of course, change, but would break on existing Glance installations. The same would be true of Nova, of course. Old instances would need to be migrated to the new key as well.
In Nova, I would say the following must all occur: 1) Change the ID in the model from autoinc keys to string/text UUIDs 2) Remove the current logic in various places that looks for integer keys 3) Add a field to the necessary tables for storing the EC2 ID (internal_id?) 4) Update all the test cases to use non-integer keys (PITA) 5) Test, test, test -jay On Fri, May 27, 2011 at 4:05 PM, Vishvananda Ishaya <[email protected]> wrote: > +1 > > We have blueprints for migrating nova but it will take some time. > > On May 27, 2011, at 1:02 PM, Mark Washenberger wrote: > >> +1 for UUIDs. >> >> If we agree on this approach, there is some difficulty incorporating it into >> nova as Ed has identified.
