# Лабораторная работа №4 - Работа с брокером сообщений
|
||||
|
||||
# Задачи:
|
||||
|
||||
Необходимо выбрать предметную область и разработать следующие приложения:
|
||||
|
||||
1) Publisher. Программа, которая создаёт один exchange с типом fanout. Программа должна раз в секунду генерировать сообщения в журнал событий согласно вашей предметной области. Например, событие "пришёл заказ" или "сообщение от пользователя" или "необходимо создать отчёт".
|
||||
2) Consumer 1. Программа, которая создаёт под себя отдельную не анонимную (!) очередь (queue) (то есть имя queue НЕ пустая строка), создаёт binding на exchange и начинает принимать сообщения (consume). Программа должна обрабатывать сообщения 2-3 секунды. Можно реализовать через обычный Thread.Sleep (для C#).
|
||||
3) Consumer 2. Аналогично Consumer 1, только сообщения необходимо обрабатывать моментально. Только имя очереди должно отличаться от Consumer 1.
|
||||
|
||||
|
||||
# Как запустить
|
||||
Командой "python 'название_файла'" в текущей папке
|
||||
|
||||
# Работа программы

||||

||||
publisher:

|
||||
|
||||
consumer_2:
|
||||
![img_1.png](img_1.png)
|
||||
|
||||
consumer_1 в одном экземпляре:
|
||||
![img_2.png](img_2.png)
|
||||
|
||||
второй consumer_1:
|
||||
![img_3.png](img_3.png)
|
||||
|
||||
наша первая очередь за 10 минут, на пике зафиксирован запуск второго экземпляра
|
||||
![img_4.png](img_4.png)
|
||||
|
||||
вторая очередь, пик из-за того, что consumer_2 запустился, когда уже были какие-то сообщения в очереди
|
||||
![img_5.png](img_5.png)
|
||||
|
||||
Можно сказать, что запуск второго экземпляра consumer_1 скорости уменьшил нагрузку на очередь.
