Hi, Dan Smith and all, I noticed followed statement in 'Icehouse tasks' in https://etherpad.openstack.org/p/IcehouseNovaExtensibleSchedulerMetricsconvert resource tracker to objects make resoruce tracker extensible no db migrations ever again!! extra specs to cover resources - use a name space How is it planned to achieve the 'no db migrations ever again'? Even with the object, we still need keep resource information in database. And when new resource type added, we either add a new column to the table. Or it means we merge all resource information into a single column as json string and parse it in the resource tracker object?.
You're right, it's not really achievable without moving to a schemaless persistence model. I'm fairly certain it was added to be humorous and should not be considered an outcome of that session.
