In this blog, we’ll dive into Kafka, a distributed streaming platform, and learn how to create a Producer and Consumer in .NET 6 using ASP.NET Core. We’ll cover Kafka’s core concepts, provide detailed explanations for each code snippet, and build a functional application that sends and receives messages.
What is Kafka?
Kafka is a high-throughput, distributed messaging system designed to handle real-time data streams. It has three key components:
Producer: Sends data (messages) to Kafka topics.
Consumer: Reads data (messages) from Kafka topics.
Broker: A Kafka server that stores and manages incoming messages. Kafka typically runs in a cluster with multiple brokers.
Kafka organizes data into topics, which are like categories for storing messages. Messages within topics are immutable and ordered.
.
3.Create a Kafka topic for this example:
kafka-topics.bat --create --topic fruit --bootstrap-server localhost:9092 --replication-factor 1 --partitions 1
Step 9: Run and Test
1.Start the Kafka and Zookeeper servers.
2.Run the .NET application:
dotnet run
3.Use a REST client like Postman to send a message
POST
http://localhost:5292/api/kafka/send?topic=fruit&message=apple
Kafka Workflow Recap
- The producer sends the message to the fruits topic.
- The Kafka broker receives and stores the message.
- The consumer reads the message from the topic and processes it.
This demonstrates the basic producer-consumer pattern in Kafka, integrated with a .NET 6 application.
You will get source code from github.
Conclusion
In this blog, we explored Kafka concepts and implemented a real-time producer-consumer application in .NET 6. Kafka is highly scalable, fault-tolerant, and suitable for distributed systems. This example can be extended to include advanced features like message keying, batch processing, error handling, and monitoring.
Happy coding!
