Structs

JoinKeyBinding

Resolved join key binding for one equality condition: which build/probe columns participate, and whether the column holds a map/struct from which a key must be extracted (e.g. UNWIND $rows AS row MATCH (m:Memory {id: row.id}) binds the probe column row with map key id, P53.26).

Functions

derive_join_bindings

Resolve the build/probe column indices for a join condition. Returns one binding per Equal key.
