Expand description

Physical query planner that converts a LogicalPlan to an ExecutionPlan suitable for execution.

Required Methods§

source

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

Create a physical plan from a logical plan

source

fn create_physical_expr( &self, expr: &Expr, input_dfschema: &DFSchema, session_state: &SessionState ) -> Result<Arc<dyn PhysicalExpr>>

Create a physical expression from a logical expression suitable for evaluation

expr: the expression to convert

input_dfschema: the logical plan schema for evaluating expr
