    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

  62. object CatalogAndIdentifier

    Extract catalog and identifier from a multi-part name with the current catalog if needed.

    Extract catalog and identifier from a multi-part name with the current catalog if needed. Catalog name takes precedence over identifier, but for a single-part name, identifier takes precedence over catalog name.

    Note that, this pattern is used to look up permanent catalog objects like table, view, function, etc. If you need to look up temp objects like temp view, please do it separately before calling this pattern, as temp objects don't belong to any catalog.
