Expand description

A planner used to add extensions to DataFusion logical and physical plans. A planner that creates a physical plan for a query.

Required Methods§

Source

fn create_physical_plan<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, logical_plan: &'life1 LogicalPlan, session: &'life2 dyn Session, ) -> Pin<Box<dyn Future<Output = Result<Arc<dyn ExecutionPlan>, DataFusionError>> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Given a LogicalPlan, create an ExecutionPlan suitable for execution

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
