Function mz_transform::join_implementation::delta_queries::plan

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

Creates a delta query plan, and any predicates that need to be lifted. It also returns the number of new arrangements necessary for this plan.

The method returns Err if any errors occur during planning.
