### Лабораторная работа №4 - Работа с брокером сообщений
|
||||
|
||||
#### Задание
|
||||
|
||||
1. Установить брокер сообщений RabbitMQ.
|
||||
2. Пройти уроки 1, 2 и 3 из RabbitMQ Tutorials на любом языке программирования.
|
||||
3. Продемонстрировать работу брокера сообщений.
|
||||
|
||||
#### Описание работы программы:
|
||||
|
||||
- Класс Publisher успешно осуществляет отправку сообщений своим клиентам.
|
||||
|
||||
- Класс Consumer1 принимает и обрабатывает сообщения с задержкой в 3 секунды, что можно заметить на видео.
|
||||
|
||||
- Класс Consumer2 мгновенно принимает и обрабатывает сообщения.
|
||||
|
||||
#### Уроки

||||
## Показания очереди orders_slow при одном запущенном экземпляре Consumer_1
|
||||
|
||||

|
||||
|
||||
## Показания очереди orders_fast
|
||||
|
||||

|
||||
|
||||
## Показания очереди orders_slow при двух запущенных экземплярах Consumer_1
|
||||

|
||||
|
||||
## Показания очереди orders_slow при трех запущенных экземплярах Consumer_1
|
||||
|
||||
