pub struct DefaultPhysicalPlanner { /* private fields */ }
Expand description

Default single node physical query planner that converts a LogicalPlan to an ExecutionPlan suitable for execution.

Implementations§

source§

impl DefaultPhysicalPlanner

source

pub fn with_extension_planners( extension_planners: Vec<Arc<dyn ExtensionPlanner + Send + Sync>> ) -> Self

Create a physical planner that uses extension_planners to plan user-defined logical nodes LogicalPlan::Extension. The planner uses the first ExtensionPlanner to return a non-None plan.

source§

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

e: the expression to convert

input_dfschema: the logical plan schema for evaluating e

input_schema: the physical schema for evaluating e
