// The source of events for the interval is typically either

// implementation of Store, if resource version = 0.

// Furthermore, an interval can be either valid or invalid at
// any given point of time. The notion of validity makes sense

resources. The scheduler then ranks each valid Node and binds the Pod to a
suitable Node. Multiple different schedulers may be used within a cluster;
kube-scheduler is the reference implementation.
