Module intersect 

WCO intersect probe execution over sorted adjacency lists.

For each probe row, every build side contributes the adjacency list of its bound value; the probe emits one output row per intersect value present in ALL lists, crossed with the matching payload rows. Sorted adjacency plus linear merge intersection keeps the per-probe cost proportional to the adjacency sizes rather than their product.

Execution core: this executor and IntersectBuild back the streaming WcoIntersectOperator, which drains chunk inputs into the build tables and probes them per probe row. Keep the row layout (probe ++ [intersect] ++ builds) in sync with the operator’s output assembly.

Structs

IntersectDataInfo

Per-build-side probe wiring: which probe column holds the bound value.

WcoIntersectExecutor

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

Functions

multiway_sorted_intersect

Incrementally intersect N sorted key lists, smallest first.

two_way_sorted_intersect

Linear merge intersection of two sorted key slices.
