Struct DecisionCachePolicy 

pub struct DecisionCachePolicy {
    pub tiers: Vec<DecisionCacheTier>,
    pub max_entry_bytes: u64,
    pub max_entries: Option<u64>,
    pub ttl_ms: u64,
    pub volatile: Vec<String>,
    pub key_dimensions: Vec<String>,
    pub on_refresh_failure: RefreshFailurePolicy,
}

The decision-result cache’s tiers, bounds and declared sources (spec 044, 3.1 and 3.6).

Fields

tiers: Vec<DecisionCacheTier>

In lookup order, memory before persistent (3.3). The persistent tier is the store persistent_cache declares.

max_entry_bytes: u64

max_entries: Option<u64>

Entries of the memory tier; present exactly when it is a tier.

ttl_ms: u64

volatile: Vec<String>

Input names, and step:<id> for an acquisition step, refreshed on every hit (3.6.2).

key_dimensions: Vec<String>

Upstream-origin dimensions the host supplies as scope handles (3.5).

on_refresh_failure: RefreshFailurePolicy

Omitted means unresolved (3.6.5); always written.
