Struct TierThresholds 

Source 
pub struct TierThresholds {
    pub hot_to_warm: u16,
    pub warm_to_dormant: u16,
    pub dormant_to_cold: u16,
    pub warm_to_hot: u16,
    pub dormant_to_warm: u16,
}
Expand description

Static fallback thresholds for tier transitions when the coherence engine is absent (DC-1). All values are in basis points (0..=10_000).

Fields§

§hot_to_warm: u16

Threshold for Hot -> Warm demotion. If cut_value + recency_score drops below this, demote from Hot.

§warm_to_dormant: u16

Threshold for Warm -> Dormant demotion.

§dormant_to_cold: u16

Threshold for Dormant -> Cold demotion.

§warm_to_hot: u16

Threshold for Warm -> Hot promotion.

§dormant_to_warm: u16

Threshold for Dormant -> Warm promotion (triggers reconstruction).

Implementations§

Source§

impl TierThresholds
