Struct OstTierConfig 

pub struct OstTierConfig {
    pub hot_capacity_bytes: u64,
    pub warm_capacity_bytes: u64,
    pub cold_capacity_bytes: u64,
    pub policy: OstTierPolicy,
    pub promotion_threshold: u32,
    pub demotion_interval_us: u64,
}

Capacity and policy configuration for the tiering engine.

Ost prefix avoids collision with TierConfig in tiering.

Fields

hot_capacity_bytes: u64

Maximum bytes that can live in the Hot tier.

warm_capacity_bytes: u64

Maximum bytes that can live in the Warm tier.

cold_capacity_bytes: u64

Maximum bytes for the Cold tier (u64::MAX = effectively unlimited).

policy: OstTierPolicy

Policy that drives automatic promotions and demotions.

promotion_threshold: u32

Access-count threshold for Warm → Hot promotion.

demotion_interval_us: u64

How often (in microseconds) to check for cold-eligible objects.
