Hello,
I'd like to request a feature freeze exception for the change,
https://review.openstack.org/#/c/149828/
This change implements NestedQuotaDriver that does the quota
management in nested projects.
The specs has been merged : https://review.openstack.org/#/c/129420/
The blueprint was approved.
https://blueprints.launchpad.net/nova/+spec/nested-quota-driver-api
But due to Feature Freeze,its status was changed to "Pending
Approval" .
Keystone already supports nested projects. This change implements the quota
management of those nested projects. Without this change(NestedQuotaDriver),
Nova will not be able to support nested projects,even if they exist in
keystone.NestedQuotaDriver is made by adding nested quota functionality to the
existing DbQuotaDriver. It is a superset of DbQuotaDriver and its supports one
to N levels of projects.That is,it can support nested as well as non-nested
projects.
The implementation of NestedQuotaDriver is over and the code is under review.
All the use cases mentioned in the blue print have been implemented. It is
supposed to become the default quota driver of nova.To avoid any potential
risks,it can be deployed as an optional driver in the current release(Kilo) and
can be made default in the next release(L).
Kindly grant freeze exception for the change.Nested projects are very important
for large organizations like CERN who are waiting for this code to get merged
in Kilo.Yahoo also has expressed keen interest in this feature.
best regards
sajeesh
