Step - tail
tail(n) keeps the last n traversers of the stream; tail() is tail(1). tail(Scope.local, n)
keeps the last n elements of the list each traverser holds.
g.V().values("name").order().tail() // ["vadas"]
g.V().values("name").order().tail(2) // ["ripple", "vadas"]
Rust: tail(n), tail_scoped(Scope::Local, n).
