class WatermarkTracker[Mark] extends WatermarkLookup[Mark] with NamedLogging

Keeps track of a boundary WatermarkTracker.highWatermark that increases monotonically. Clients can do one of the following:

The WatermarkTracker is effectively used to enforce mutual exclusion between two types of tasks.
