Trait polars_lazy::physical_plan::PhysicalPlanner

pub trait PhysicalPlanner {
    fn create_physical_plan(
        &self, 
        root: Node, 
        lp_arena: &mut Arena<ALogicalPlan>, 
        expr_arena: &mut Arena<AExpr>
    ) -> Result<Box<dyn Executor>>;
}

This is supported on crate feature compile only.

A type that implements this transforms a LogicalPlan to a physical plan.

We could produce different physical plans with different goals in mind, e.g. memory optimized performance optimized, out of core, etc.

Required methods

fn create_physical_plan(
    &self,
    root: Node,
    lp_arena: &mut Arena<ALogicalPlan>,
    expr_arena: &mut Arena<AExpr>
) -> Result<Box<dyn Executor>>
