-----------------------------------
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.
