Trait datafusion::physical_optimizer::optimizer::PhysicalOptimizerRule

pub trait PhysicalOptimizerRule {
    fn optimize(
        &self,
        plan: Arc<dyn ExecutionPlan>,
        config: &SessionConfig
    ) -> Result<Arc<dyn ExecutionPlan>>;
    fn name(&self) -> &str;
}

PhysicalOptimizerRule transforms one [‘ExecutionPlan’] into another which computes the same results, but in a potentially more efficient way.

Required Methods

fn optimize(
    &self,
    plan: Arc<dyn ExecutionPlan>,
    config: &SessionConfig
) -> Result<Arc<dyn ExecutionPlan>>

Rewrite plan to an optimized form

fn name(&self) -> &str

A human readable name for this optimizer rule
