Examples of org.apache.pig.impl.util.SpillableMemoryManager

org.apache.pig.impl.util.SpillableMemoryManager
This class Tracks the tenured pool and a list of Spillable objects. When memory gets low, this class will start requesting Spillable objects to free up memory.
Low memory is defined as more than 50% of the tenured pool being allocated. Spillable objects are tracked using WeakReferences so that the objects can be GCed even though this class has a reference to them.
