Struct PlanningPolicy 

pub struct PlanningPolicy {
    pub keyed_hash_join: KeyedHashJoinStrategyOptions,
    pub dynamic_filter: DynamicFilterExecutionOptions,
}

Thresholds applied during plan optimization, admission, and execution.

The policy accompanies the AnalysisContext across planning passes and is captured in the resulting admission artifact rather than embedded directly in plan IR. This separation allows plan IR fingerprints to remain invariant to policy adjustments while recording the active policy in the admitted artifact. The type implements Copy because passes receive it by value without shared state.

Fields

keyed_hash_join: KeyedHashJoinStrategyOptions

Keyed-hash join strategy thresholds.

dynamic_filter: DynamicFilterExecutionOptions

Dynamic-filter route and application thresholds.

Implementations

impl PlanningPolicy

pub fn validate(&self) -> Result<(), QueryError>

Rejects thresholds the optimizer and the engine cannot honor.

Each component policy validates its own ordering constraints and reports the first failure with the field names in its facts. Zero is accepted everywhere as “branch disabled”; see the component docs.
