If you prefer short code, you can convert the Schema.apply method (which is what is called when creating a case class instance) into a function and use the .tupled method to convert it from a function taking three arguments to a function taking a 3-tuple:
rdd.map((Schema.apply _).tupled)
Both of these have the same result. Personally, Iād probably only use the latter, if there is a lot of parameters.
