Spark Streaming是否支持迭代为Flink？

Question

例如，这里是Flink的程序，它从一系列整数中连续减去1，直到它们达到零： Flink iterations

DataStream<Long> someIntegers = env.generateSequence(0, 1000);

IterativeStream<Long> iteration = someIntegers.iterate();

DataStream<Long> minusOne = iteration.map(new MapFunction<Long, Long>() {
  @Override
  public Long map(Long value) throws Exception {
    return value - 1 ;
  }
});

DataStream<Long> stillGreaterThanZero = minusOne.filter(new FilterFunction<Long>() {
  @Override
  public boolean filter(Long value) throws Exception {
    return (value > 0);
 }
});

iteration.closeWith(stillGreaterThanZero);

DataStream<Long> lessThanZero = minusOne.filter(new FilterFunction<Long>() {
    @Override
    public boolean filter(Long value) throws Exception {
       return (value <= 0);
    }
});
