A single cache tier in the multi-tier architecture

Fields

backend: Arc<dyn L2CacheBackend>

The backend for this tier

tier_level: usize

Tier level (1 for fastest, increases for slower/cheaper tiers)

promotion_enabled: bool

Whether to promote keys FROM lower tiers TO this tier

promotion_frequency: usize

Promotion frequency (N) - promote with 1/N probability

ttl_scale: f64

TTL multiplier for this tier (e.g., L2 might store for 2x L1 TTL)

stats: TierStats

Statistics for this tier
