Struct PhysicalPlanBuilder 

Source 
pub struct PhysicalPlanBuilder;
Expand description

Builds an arena PhysicalPlan from a PlanNodeEnum tree.

Implementations§

Source§

impl PhysicalPlanBuilder

Source

pub fn build( node: &PlanNodeEnum, ctx: &mut PhysicalPlanBuildContext, exec_ctx: &ExecutionContext, ) -> Result<PhysicalPlan, PlanBuildError>

Build a complete PhysicalPlan from a plan node.

Walks the PlanNodeEnum tree directly, creating arena operators and a fragment DAG. When ctx.partition_spec is set and the tree is partitionable, a partitioned plan (N local source fragments + one exchange fragment + global fragments) is produced instead; otherwise the single-tree path is used and the reason is recorded in ctx.parallel_fallback_reason.
