Trait datafusion_optimizer::optimizer::OptimizerRule

source · 
pub trait OptimizerRule {
    fn optimize(
        &self,
        plan: &LogicalPlan,
        optimizer_config: &mut OptimizerConfig
    ) -> Result<LogicalPlan>;
    fn name(&self) -> &str;
}
Expand description

OptimizerRule transforms one [‘LogicalPlan’] into another which computes the same results, but in a potentially more efficient way. If there are no suitable transformations for the input plan, the optimizer can simply return it as is.

Required Methods
