Function transform::join_implementation::differential::plan

pub fn plan(
    join: &MirRelationExpr, 
    input_mapper: &JoinInputMapper, 
    available: &[Vec<Vec<MirScalarExpr>>], 
    unique_keys: &[Vec<Vec<usize>>]
) -> Option<MirRelationExpr>

Creates a linear differential plan, and any predicates that need to be lifted.
