BarrierAck

laminar_core::cluster::control::barrier

Struct BarrierAck 

Source 
pub struct BarrierAck {
    pub epoch: u64,
    pub ok: bool,
    pub error: Option<String>,
    pub local_watermark_ms: Option<i64>,
}
Expand description

Follower ack. ok = false forces the leader to abort instead of wait.

Fields§

§epoch: u64

Epoch being acknowledged.

§ok: bool

false = snapshot failed locally; leader should abort.

§error: Option<String>

Free-text error; populated when ok = false.

§local_watermark_ms: Option<i64>

Follower’s local watermark at ack time (ms since epoch or arbitrary monotonic domain, matching the source’s event-time units). The leader folds this into the cluster-wide min emitted in the matching Commit announcement.

None means the follower’s watermark is unset (fresh boot, no source events yet) — treated as “infinity” by the leader: it doesn’t cap the cluster min downward.
