FeedbackWindowTinyLfuPolicy (simulator 3.1.5 API)

java.lang.Object
- com.github.benmanes.caffeine.cache.simulator.policy.sketch.feedback.FeedbackWindowTinyLfuPolicy

All Implemented Interfaces:

Policy, Policy.KeyOnlyPolicy
```
public final class FeedbackWindowTinyLfuPolicy
extends Object
implements Policy.KeyOnlyPolicy
```
The Window TinyLfu algorithm where the size of the admission window is adjusted based on the workload. If a candidate is rejected multiple times within a sample period then the window is increased. The window is decreased on an eviction if no adjustments have been made for at least two periods. This allows the policy to dynamically decide whether it should favor recency (larger window) or frequency (smaller window) based on the workload's characteristics. If the workload changes then the policy will adapt to the new environment.
