Struct AdaptiveTtlConfig 

pub struct AdaptiveTtlConfig {
    pub min_ttl_secs: u32,
    pub max_ttl_secs: u32,
    pub grace_secs: u32,
    pub max_heartbeats_per_second: u32,
    pub failover_ttl_secs: u32,
}

Adaptive-TTL heartbeat configuration. Mirrors Nomad’s design: the leader caps cluster-wide heartbeat rate to a constant by stretching individual workers’ TTLs as the cluster grows.

Fields

min_ttl_secs: u32

max_ttl_secs: u32

grace_secs: u32

max_heartbeats_per_second: u32

failover_ttl_secs: u32

Implementations

impl AdaptiveTtlConfig

pub fn compute_ttl(&self, n_workers: u32) -> u32

Compute the TTL to hand a worker, given the current cluster size. Formula matches Nomad: clamp(N / max_hb_per_sec, min, max).
