Example 1
@Override
public void apply(Tuple tuple, TimeWindow timeWindow, Iterable<TripDuration> iterable, Collector<AverageTripDuration> collector) {
  if (Iterables.size(iterable) > 1) {
    String location = Iterables.get(iterable, 0).pickupGeoHash;
    String airportCode = Iterables.get(iterable, 0).airportCode;

    long sumDuration = StreamSupport
        .stream(iterable.spliterator(), false)
        .mapToLong(trip -> trip.tripDuration)
        .sum();

    double avgDuration = (double) sumDuration / Iterables.size(iterable);

    collector.collect(new AverageTripDuration(location, airportCode, sumDuration, avgDuration, timeWindow.getEnd()));
