Struct SessionWindowConfig 

pub struct SessionWindowConfig {
    pub gap_duration: Duration,
    pub min_events: usize,
    pub max_session_duration: Option<Duration>,
    pub allowed_lateness: Duration,
}

Configuration for the session window processor.

Fields

gap_duration: Duration

Maximum gap between consecutive events before the session is closed.

min_events: usize

Minimum number of events required for a session to be emitted. Sessions with fewer events are silently discarded.

max_session_duration: Option<Duration>

If set, force-close a session whose span exceeds this duration.

allowed_lateness: Duration

Bounded out-of-order tolerance.

The processor assumes events arrive in non-decreasing timestamp order. An event whose timestamp is earlier than the previously processed event by more than allowed_lateness is rejected by SessionWindowProcessor::process with StreamingError::InvalidState, rather than being silently mis-assigned to the wrong session. Defaults to Duration::ZERO, which rejects any strictly out-of-order event.
