Expand description

Configuration for tiered memory behavior

Fields§

§hot_retention_hours: u64

Hours before considering demotion from hot to warm

§warm_retention_hours: u64

Hours before considering demotion from warm to cold

§hot_importance_threshold: f32

Minimum importance score to stay in hot tier

§warm_importance_threshold: f32

Minimum importance score to stay in warm tier

§max_hot_messages: usize

Maximum messages in hot tier

§max_warm_summaries: usize

Maximum summaries in warm tier

§session_ttl_secs: Option<u64>

Optional TTL for session-tier messages, in seconds.

When set, every message added via TieredMemory::add_message receives an expires_at timestamp of now + session_ttl_secs. Expired entries are removed by TieredMemory::evict_expired or lazily during TieredMemory::search_adaptive.

None (the default) means no TTL — messages persist until explicitly deleted or demoted.

§temporal_boost: f32

Extra recency weight added when a query is detected as temporally sensitive (e.g. contains “recent”, “latest”, “today”).

The additional weight is proportional to the query’s temporal score (0.0–1.0). The three weights are renormalised so they always sum to 1.0. Default: 0.3.

§fast_decay: bool

Use a faster recency decay rate (exp(-0.05 × h) instead of exp(-0.01 × h)) when the query is temporally sensitive.

Default: false.

§max_mental_models: usize

Maximum number of synthesised mental models to retain.

Default: 500.
