Struct HedgeParams

Source

pub struct HedgeParams {
    pub hedge_after: Duration,
    pub hedge_max: u32,
}

Expand description

Resolved (validated) hedge parameters for one upstream (DW-063). hedge_after is None when hedging is disabled (no hedge block or hedge_after_ms == 0). When enabled, a speculative duplicate is sent after hedge_after without a response; at most hedge_max copies per request.

Fields§

§hedge_after: Duration

Tail-latency threshold before a hedge copy is sent.

§hedge_max: u32

Maximum speculative copies per request.
