Recipe

To set up the basic Kafka messaging model, we need to understand a couple of terms. This article gives you an extremely basic overview of Apache Kafka.

A couple of the most important parts of Apache Kafka.
  1. Zookeeper
  2. Kafka Server
  3. Topic (Channel)
  4. Producer (Sender)
  5. Consumer (Receiver)
Start Zookeeper Server

zookeeper-server.bat ../../config/zookeeper.properties

Apache Kafka library 
Apache Kafka library 
Start Kafka Server

kafka-server.bat ../../config/server.properties

Apache Kafka library 
Apache Kafka library
Create Topic

kafka-topics.bat --create --topic KafkaDemo --zookeeper localhost:2181 --replication-factor 1 --partitions 1 

Apache Kafka library
We can see an entry of created topics in the running Kafka server.

Create Producer (Sender)

kafka-console-producer.bat --broker-list localhost:9092 --topic KafkaDemo

Apache Kafka library
Create Consumer(Receiver)

kafka-console-consumer.bat --zookeeper localhost:2181 --topic KafkaDemo --from-beginning

Apache Kafka library 
Write a message in Producer console, hit enter and we will receive it in the consumer console.

And here, we are done with an extremely basic Apache Kafka messaging setup. I have not covered Partition, Broker, Cluster and many more topics in this blog. The intention was just to explain how quickly we can set up the Kafka messaging system.
