Alena Prokharchyk resolved CLOUDSTACK-6318.
-------------------------------------------
Resolution: Won't Fix
Resolving as won't fix. DB upgrade should be considered to be completed only
when both databases - cloud and cloud_usage are updated. If we postpone
cloud_usage db upgrade, it can cause all kinds of problems during the usage
record updates.
To address "cloud-usage might take longer to update, but is in most of the
installation not that critical" - for the environments where usage installation
is not critical, this problem - long time update for cloud_usage due to lots of
data - won't occur at all. As those environments most likely won't have usage
running if usage is irrelevant for them. For the environments where usage
matters, we should be consistent with the db upgrade process.

> Components: Install and Setup
> Affects Versions: 4.2.0

>
> when updating cloudstack on an environement which is already running for a
> certain time and has a bigger ammount of instances cloud_usage db will become
> quite big.
> in this situaion the schema updates for the databases can take quite a long
> time, during this time cloudstack management is offline.
> proposal:
> cloudstack-managent does only schema updates on cloud db
> cloudstack-usage does the scema updates on cloud_usage
> this way cloudstack-management will be back online after the update much
> quicker and only dependant of the size of cloud db
> cloud-usage might take longer to update, but is in most of the installation
> not that critical
