Hi everybody,
this question may sounds stupid, but i would like to have it clear

what happens if inside a dataset transformation (e.g. a map) I use something that is declared somewhere else, like a variable or a dataset, and not passed as broadcast dataset nor parameter in the constructor of a rich function?

for example

val a = 2
dataset.filter((v) => v._1 == a)

or

dataset1.flatmap((v) => /* something that uses dataset2 */)


thanks
