WcoIntersectExecutor

linkrs_query::executor::streaming::operators::intersect

Struct WcoIntersectExecutor 

Source 
pub struct WcoIntersectExecutor { /* private fields */ }
Expand description

N-way intersect executor: one probe side plus N sorted build tables.

Output row layout: probe_row ++ [intersect_value] ++ build_row_1 ++ ... ++ build_row_N, where each build_row_i is a full matching build row. Callers resolve column positions through the slot layout before constructing the executor.

Implementations§

Source§

impl WcoIntersectExecutor

Source

pub fn new(builds: Vec<IntersectBuild>, bound_cols: Vec<usize>) -> Self

Create an executor over finished build tables. bound_cols[i] is the probe-side column holding the bound value for builds[i].

Source

pub fn num_builds(&self) -> usize

Source

pub fn into_builds(self) -> Vec<IntersectBuild>

Release the build tables. The streaming operator moves tables out per probe chunk and restores them afterwards so consecutive chunks reuse the same sealed state without cloning.

Source

pub fn probe_row(&self, probe_row: &[Value]) -> Vec<Vec<Value>>

Probe with one row; returns zero or more output rows.

Source

pub fn probe_rows(&self, probe_rows: &[Vec<Value>]) -> Vec<Vec<Value>>

Probe with many rows, concatenating the per-row outputs.
