Несколько очередей с пулами потоков не выполняют все задачи

/ 17 апреля 2020

Цель состоит в том, чтобы иметь две очереди: первая очередь питает вторую очередь, и каждая очередь имеет различное ограничение скорости. Например, первый работник, работающий в первой очереди, должен выполнять 5 запросов каждые 5 секунд, а второй работник должен выполнять 2 запроса каждые две секунды. Или может быть ограничение скорости с 10 запросами каждые 2 секунды или 20 запросами каждые 3 секунды.

Мой код выполняется, однако он не завершает sh время, кажется, выключено. 

for x in range(20):
    first_queue.put(x)

def first_worker_job(queue):
    v = first_queue.get()
    log.info(f"first: {v}")
    second_queue.put(v)

def first_worker(first_queue):
    while True:
        with concurrent.futures.ThreadPoolExecutor(max_workers=5) as executor:
            furtureIteams = {
                executor.submit(first_worker_job, first_queue): index
                for index in range(5)
            }
            for future in concurrent.futures.as_completed(furtureIteams):
                f = furtureIteams[future]

            time.sleep(5)

def second_worker_job(queue):
    v = second_queue.get()
    log.info(f"second: {v}")

def second_worker(second_queue):

    while True:
        with concurrent.futures.ThreadPoolExecutor(max_workers=2) as executor:
            furtureIteams = {
                executor.submit(second_worker_job, first_queue): index
                for index in range(2)
            }
            for future in concurrent.futures.as_completed(furtureIteams):
                f = furtureIteams[future]

            time.sleep(2)

first_thread = threading.Thread(target=first_worker, args=(first_queue,))
first_thread.setDaemon(True)
first_thread.start()

second_thread = threading.Thread(target=second_worker, args=(second_queue,))
second_thread.setDaemon(True)
second_thread.start()

first_queue.join()
second_queue.join()

second_thread.join()
first_thread.join()

Вывод:
