slowQueryThreshold property
Threshold above which a query's wall-clock duration triggers a
SlowQueryDetected event on IAdminService.events. When null,
the runtime falls back to queryTimeout * 0.8 if a query timeout
is set; otherwise no slow-query events are emitted.
The threshold is observability-only — it does not cancel the query. Useful for dashboards / alerting on regressions.
Implementation
final Duration? slowQueryThreshold;
