# Лабораторная работа 4
|
||||
Данная работа посвящена работе с брокером сообщений RabbitMQ.
|
||||
## Прохождение tutorial
|
||||
Для каждого из уроков был создан отдельный проект, где в Program создаётся producer и concumer(s), а для подтверждения работоспособности использовалась консоль. Скриншоты подтверждения
|
||||
### "Hello World!"
|
||||
|
||||
### Work Queues
|
||||
|
||||
### Publish/Subscribe
|
||||
|
||||
## Описание
|
||||
Для демонстрационной работы была выбрана предметная область гипотетический системы обработки посылок. Имеется некий сканер, который отправляет устройству сведения через очереди (какие штрих-коды он отсканировал, или, если произошла какая-то ошибка - какая это ошибка).
|
||||
## Запуск
|
||||
Для запуска лабораторной работы необходимо иметь запущенный движок Docker на устройстве.
|
||||
Необходимо перейти в папку, где располагается данный файл. Далее открыть терминал и ввести команду:
|
||||
```
|
||||
docker compose up -d --build
|
||||
```
|
||||
Важно, чтобы в этот момент на компьютере был свободен порт 8081 и 5672.
|
||||
Результаты работы системы можно простелить через Web GUI брокера(http://localhost:8081) или посмотрел логи контейнеров.
|
||||
## Исследования
|
||||
Первоначальный вариант запуска предполагает, что имеется всего 2 потребителя:
|
||||
1. Тратит на обработку сообщения 2-3 секунды
|
||||
2. Тратит на обработку сообщения минимальное возможное время(условно - не тратит вообще ничего)
|
||||
Так как производитель отправляет сообщения 1 раз в секунду, можно понять, что первый потребитель не справится с потоком сообщения, в то время как второй будет успевать обрабатывать их. На практике это подтверждается: очередь, куда из exchange попадают сообщения для первого потребителя только растёт(не справляемся с нагрузкой). В то время как у второго значения практически всегда - о.
|
||||
<br/>
|
||||
|
||||
<br/>
|
||||
|
||||
<br/>
|
||||
Учитывая описанное ранее, можно попробовать решить проблему первого сервиса за счёт горизонтального масштабирования. Теоретически должно хватить 3-х копий, чтобы сообщения не застаивались. На практике эта гипотеза подтвердилась. Очередь пусть и не пустеет, но не становится длиннее.
|
||||
<br/>
|
||||
|
||||
|
||||
## Видеодемонстрация
|
||||
Был записан видеоролик, демонстрирующий процесс запуска и работы системы. Он расположен по [адресу](https://drive.google.com/file/d/1l7LXVXOb-oRNdS8aJGgeV7xbGCOpi1Es/view?usp=sharing)
|
||||
Стоит отметить, что ошибки, которые были видны в логах сервисов связаны с относительно долгим стартом RabbitMQ (несмотря на depands_on брокер не усаапевает подняться, когда сервисы встают, и они не могут подключиться, из-за чего и падают. но из за политики перехапуска их раз за разом востанавливают, до тех пор пока брокер полностью не будет готов принимать сообщения)
