// will be processed by this scheduler, based on pod's "spec.SchedulerName".

// PercentageOfNodeToScore is the percentage of all nodes that once found feasible
// for running a pod, the scheduler stops its search for more feasible nodes in
// the cluster. This helps improve scheduler's performance. Scheduler always tries to find
// at least "minFeasibleNodesToFind" feasible nodes no matter what the value of this flag is.
// Example: if the cluster size is 500 nodes and the value of this flag is 30,
// then scheduler stops finding further feasible nodes once it finds 150 feasible ones.
// When the value is 0, default percentage (5%--50% based on the size of the cluster) of the
// nodes will be scored.
PercentageOfNodesToScore int32
// Duration to wait for a binding operation to complete before timing out
// Value must be non-negative integer. The value zero indicates no waiting.
