Hi all,
I am resuming this thread following the session we had at the summit in
Paris (etherpad here [1])
While there was some sort of consensus regarding what this library
should do, and how it should do it, the session ended with some open
questions which we need to address before finalising the specification.
There was a rather large consensus that the only viable architecture
would be one where the quota management library owns resource usage
data. However, this raises further concerns around:
- ownership of resource usage records. As the quota library owns usage
data, it becomes the authoritative source of truth for it. This could be
problematic in some projects, particularly nova, where the resource
tracker currently own usage data.
Well, just to be clear... the resource tracker in Nova owns the usage
records for the compute node, not the usage records for a tenant or user
(the quota driver and DB tables own that data).
Best,
-jay
