      Description

      We have no visibility into whether reservations made by preemption are actually consumed or simply expire.

      We are currently collecting stats for the size of preemption/reservation BiCache. We could additionally collect (a) cache expiration stats and (b) reservation entry removals in TaskSchedulerImpl.taskChanged() to monitor overall preemption effectiveness.
