Whiteboard

(kiennt) Hi folks,

After take week(s) to follow & investigate how to implement this blueprint, I recognize that unified limit API isn't ready yet:
* Unified Limit API is labeled as experimental [1]
* The implementation needs a lib called oslo.limit [2]. But a lib still in Work-in-progress phase [3]

We can't implement a new quota that uses an unified limit api now, But we can implement quota support at service level (like other projects) which has several limits itself. Should we do that way? Or wait for an unified limit API be stable. Please share your thoughts :)

(hongbin) I would vote for implement our own quota API.
