  8. def buildBalancedPredicate(expressions: Seq[Expression], op: (Expression, Expression) => Expression): Expression

    Builds a balanced output predicate in bottom up approach, by applying binary operator op pair by pair on input predicates exprs recursively.

    Builds a balanced output predicate in bottom up approach, by applying binary operator op pair by pair on input predicates exprs recursively. Example: exprs = [a, b, c, d], op = And, returns (a And b) And (c And d) exprs = [a, b, c, d, e, f], op = And, returns ((a And b) And (c And d)) And (e And f)

  9. def canEvaluate(expr: Expression, plan: LogicalPlan): Boolean

    Returns true if expr can be evaluated using only the output of plan.

    Returns true if expr can be evaluated using only the output of plan. This method can be used to determine when it is acceptable to move expression evaluation within a query plan.

    For example consider a join between two relations R(a, b) and S(c, d).

    - canEvaluate(EqualTo(a,b), R) returns true - canEvaluate(EqualTo(a,c), R) returns false - canEvaluate(Literal(1), R) returns true as literals CAN be evaluated on any plan

    Returns a filter that its reference is a subset of outputSet and it contains the maximum constraints from condition.

    Returns a filter that its reference is a subset of outputSet and it contains the maximum constraints from condition. This is used for predicate pushdown. When there is no such filter, None is returned.

    Find the origin of where the input references of expression exp were scanned in the tree of plan, and if they originate from a single leaf node. Returns optional tuple with Expression, undoing any projections and aliasing that has been done along the way from plan to origin, and the origin LeafNode plan from which all the exp

    Normalize the exprIds in the given expression, by updating the exprId in AttributeReference with its referenced ordinal from input attributes.

    Normalize the exprIds in the given expression, by updating the exprId in AttributeReference with its referenced ordinal from input attributes. It's similar to BindReferences but we do not use BindReferences here as the plan may take the expression as a parameter with type Attribute, and replace it with BoundReference will cause error.

  41. def normalizePredicates(predicates: Seq[Expression], output: AttributeSeq): Seq[Expression]

    Composes the given predicates into a conjunctive predicate, which is normalized and reordered.

    Composes the given predicates into a conjunctive predicate, which is normalized and reordered. Then returns a new sequence of predicates by splitting the conjunctive predicate.
