> As of now BasicOperators enumerates all the cases to match LogicalPlan to SparkPlan, but some of cases are just a kind of simple transformation as the code stated as 'pass through', which just need to provide same parameters except converting LogicalPlan to SparkPlan via calling `planLater`.
> We can automate this via leveraging reflection. ScalaReflection already has many methods to leverage, so we would be good to go.
