PresenceState

reddb::storage::queue

Enum PresenceState 

Source 
pub enum PresenceState {
    Active,
    Stale,
    Expired,
}
Expand description

Lifecycle bucket derived from last_seen_age_ms vs the configured ttl_ms. Snapshot consumers (Red UI, virtual tables) read this flag and never re-derive the rule.

Variants§

§

Active

Last heartbeat within ttl_ms. Worker is alive.

§

Stale

Beyond ttl_ms but within 2 * ttl_ms. Worker missed a beat; surface a warning in Red UI but keep the row visible.

§

Expired

Beyond 2 * ttl_ms. Worker is assumed dead; will be pruned on the next sweep but still appears in the snapshot until then so the UI can show “last seen 5 minutes ago” rather than a gap.
