Hi, Dan Smith and all,
I noticed followed statement in 'Icehouse tasks' in https://etherpad.openstack.org/p/IcehouseNovaExtensibleSchedulerMetrics
convert 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?.
