[jira] [Created] (AURORA-878) Persist Host Attributes along Offer

Zameer Manji created AURORA-878:
-----------------------------------

             Summary: Persist Host Attributes along Offer
                 Key: AURORA-878
                 URL: https://issues.apache.org/jira/browse/AURORA-878
             Project: Aurora
          Issue Type: Task
          Components: Scheduler
            Reporter: Zameer Manji


At a large production cluster [~wfarner] and I have noticed that a lot of time is spent reading from the attribute store during scheduling. This is because when scheduling tasks we need to check the attributes of the slave before accepting an offer. We do this to compute diversity constraints.

We can prevent frequent reading from the attribute store in this process by persisting attributes alongside the offers. That way when we get an offer from a slave we can check the diversity constraints without reading from the AttributeStore.
