PhysicalMapper

linkrs_query::planning::physical_mapper

Struct PhysicalMapper 

Source 
pub struct PhysicalMapper;
Expand description

Full logical-to-physical mapper.

The entry points are PhysicalMapper::map (logical tree to physical tree) and PhysicalMapper::merge_physical_hints (overlay of the cost-based physical choices onto a mapped tree).

Implementations§

Source§

impl PhysicalMapper

Source

pub fn map(logical: LogicalNodeEnum) -> PlanNodeEnum

Convert a logical plan tree into a physical plan tree.

The structure mirrors the shared logical-to-physical converter; scan nodes carrying an index hint become index scans instead.

Source

pub fn merge_physical_hints( mapped: PlanNodeEnum, physical: PlanNodeEnum, ) -> (PlanNodeEnum, Vec<String>)

Merge a fully mapped tree with the cost-based physical tree.

The mapped tree supplies structure (notably factorization operator positions); the physical tree supplies cost-based access choices. Returns the merged tree plus notes for every position where the trees diverged and the physical choice won, so no fallback is silent.
