> 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
> caching 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.
