Struct CacheConfig 

pub struct CacheConfig {
    pub default_ttl_secs: u64,
    pub swr_window_secs: u64,
    pub max_in_memory_entries: usize,
}

Runtime-configurable cache parameters.

Loaded from Settings at startup; Default reflects the v1 proposal values so callers can construct a sensible default without a settings handle.

Fields

default_ttl_secs: u64

Time-to-live in seconds (default 30, from Settings.cache_ttl_secs).

swr_window_secs: u64

How long stale data may be served while background revalidation runs. Default 60 s — twice the default TTL so there is always a window without a blocking S3 fetch during normal browsing.

max_in_memory_entries: usize

Maximum number of entries kept in the in-memory LRU map. Eviction is LRU; disk is unaffected by eviction.
