Struct CacheConfig 

pub struct CacheConfig {
    pub max_entries: usize,
    pub ttl: Duration,
    pub negative_ttl: Duration,
    pub background_refresh: bool,

    pub enable_metrics: bool,
}

Configuration for the tenant cache.

Fields

max_entries: usize

Maximum number of entries in the cache.

ttl: Duration

Time-to-live for cached entries.

negative_ttl: Duration

background_refresh: bool

Enable background refresh before TTL expires.

refresh_threshold: f64

How long before TTL to start background refresh (e.g., 0.8 = refresh at 80% of TTL).

enable_metrics: bool

Enable metrics collection.
