test.java

public class ThrottleLast {

    @Test
    public void testThrottleLastClosing() {

        final PublishSubject<Integer> subject = PublishSubject.create();
        Observable<Integer> share = subject.share();
        Observable<Integer> closing = share.throttleLast(10, TimeUnit.MILLISECONDS);

        share.window(closing).flatMap(this::procWindow).subscribe();

        IntStream.range(0, 100).forEach(subject::onNext);

        Uninterruptibles.sleepUninterruptibly(1, TimeUnit.SECONDS);
    }

    private Observable<?> procWindow(Observable<Integer> stringObservable) {
        Set<Integer> seen = Sets.newConcurrentHashSet();
        return stringObservable
                .doOnNext(n -> Uninterruptibles.sleepUninterruptibly(5, TimeUnit.MILLISECONDS))
                .doOnNext(seen::add)
                .doOnCompleted(() -> System.out.println(seen));
    }
}
