w-TinyLFU eviction algorithm config.

Fields

window_capacity_ratio: f64

window capacity ratio of the total cache capacity.

Must be in (0, 1).

Must guarantee window_capacity_ratio + protected_capacity_ratio < 1.

protected_capacity_ratio: f64

protected capacity ratio of the total cache capacity.

Must be in (0, 1).

Must guarantee window_capacity_ratio + protected_capacity_ratio < 1.

cmsketch_eps: f64

Error of the count-min sketch.

See CMSketchU16::new.

cmsketch_confidence: f64

Confidence of the count-min sketch.

See CMSketchU16::new.
