Fields§

§groups: usize§search_mode: SearchMode§query_digest: Option<String>§selected_plan: String§selected_plan_fingerprint: String

The physical operator-tree shape. Bound values are intentionally absent.

§selected_plan_cost: PlanCost§selected_plan_cost_breakdown: PlanCostBreakdown§selected_plan_properties: PhysicalProperties§selected_plan_cardinality_estimates: Vec<OperatorCardinalityEstimate>

Per-operator cardinalities keyed by stable, plan-local pre-order identities.
