public final class GDWheelPolicy
extends Object
implements Policy

Greedy Dual Wheel (GD-Wheel) algorithm.

The algorithm is explained by the authors in GD-Wheel: A Cost-Aware ReplacementPolicy for Key-Value Stores. This a cost-aware cache policy, which takes into account the access times (i.e. the cost of recomputing or fetching the data). This is also a weighted policy, meaning it supports non-uniform entry sizes.
