Andreas Fuchs created CLOUDSTACK-6318:
-----------------------------------------

             Summary: Cloudstack upgrade takes long time on big cloud_usage databases
                 Key: CLOUDSTACK-6318
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6318
             Project: CloudStack
          Issue Type: Improvement
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Install and Setup
    Affects Versions: 4.2.0
            Reporter: Andreas Fuchs
            Priority: Minor
             Fix For: Future


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
