  57. def sameResult(plan: LogicalPlan): Boolean

    Returns true when the given logical plan will return the same results as this logical plan.

    Returns true when the given logical plan will return the same results as this logical plan.

    Since its likely undecideable to generally determine if two given plans will produce the same results, it is okay for this function to return false, even if the results are actually the same. Such behavior will not affect correctness, only the application of performance enhancements like caching. However, it is not acceptable to return true if the results could possibly be different.

    By default this function performs a modified version of equality that is tolerant of cosmetic differences like attribute naming and or expression id differences. Logical operators that can do better should override this function.
