Two simple .net core console apps (producer & consumer) using Kafka as a message broker. As addition you can use Confluent Control Center by using Option 2 (see below) with Docker.

Install Kafka (latest version) on your local machine: [https://kafka.apache.org/downloads]

bin\windows\zookeeper-server-start.bat config/zookeeper.properties

bin\windows\kafka-server-start.bat config/server.properties

git clone https://github.com/confluentinc/examples.git

Make sure you have at least 8192MB Memory allocated in docker (Settings, Advanced).

cd cp-all-in-one

docker-compose up -d --build

docker-compose ps

All states should have the value 'Up'

Go to a webbrowser and start Confluent Control Center: localhost:9021

Under 'topics' you can create a new topic called 'testTopic' with 0 partitions.

cd bookstore-producer

dotnet run args[-newmsg, -topic, -partition] (i.e. dotnet run -newmsg 24 -topic testTopicP12 -partition 12)

The result should be like that:

• Press Ctrl+C to exit
• Delivered 'This is a test: 5' to: testTopicP12 [[5]] @19
• Delivered 'This is a test: 2' to: testTopicP12 [[2]] @14
• Delivered 'This is a test: 17' to: testTopicP12 [[5]] @21
• ...

cd bookstore-consumer

dotnet run args[-topic, -group] (i.e. dotnet run -topic testTopicP12 -group testTopic12)

The result should be like that:

• Press Ctrl+C to exit
• Topic: testTopicP12
• Group: testTopic12
• Message 'This is a test: 22' at: 'testTopicP12 [[10]] @10'.
• Message 'This is a test: 10' at: 'testTopicP12 [[10]] @11'.
• Message 'This is a test: 22' at: 'testTopicP12 [[10]] @12'.
• ...
