Struct TierPolicy 

pub struct TierPolicy {
    pub hot_to_warm_days: u64,
    pub warm_to_cold_days: u64,
    pub cold_to_frozen_days: u64,
    pub min_size_for_cold: u64,
    pub compress_cold: bool,
}

Policy controlling when blocks graduate to colder tiers.

Fields

hot_to_warm_days: u64

Days of inactivity before a Hot block is demoted to Warm.

warm_to_cold_days: u64

Days of inactivity before a Warm block is demoted to Cold.

cold_to_frozen_days: u64

Days of inactivity before a Cold block is promoted to Frozen.

min_size_for_cold: u64

Blocks smaller than this (bytes) are never demoted to Cold or Frozen.

compress_cold: bool

Whether Cold/Frozen blocks should have compression applied.

Implementations

impl TierPolicy

pub fn new( hot_to_warm_days: u64, warm_to_cold_days: u64, cold_to_frozen_days: u64, min_size_for_cold: u64, compress_cold: bool, ) -> Self

Create a new policy with explicit thresholds.

pub fn days_to_secs(days: u64) -> u64

Convert a day count to seconds (seconds = days * 86 400).
