    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)

  8. 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

    Merge an Alias(Alias(x)) into Alias(x) preserving metadata.

    If the outer alias has explicit metadata, it is preserved. Else if the inner alias has explicit metadata, the result has explicit outer.metadata. Else both are deriving the metadata. the result is deriving metadata, with the union of noninheritable keys.

    alias

    An Alias with a child Alias, Alias(Alias(x))

    Merge any stack of aliases under the top-level alias, and then drops any aliases deeper in the expression tree. So Alias1(Alias2(Alias3(Foo(Alias4(x))))) becomes Alias5(Foo(x)) where Alias5 preserves the metadata of Alias{1,2,3} and the name and exprId of Alias1. Alias4 is simply removed.
