Producing the sample messages

About this task

In the real-world practice, the system that produces messages to Kafka is completely decoupled. While in this scenario, Kafka itself is used to produce the sample messages. You need to perform the following operations to produce these messages:

Procedure

Create the Kafka topic to be used to categorize the messages. The following command is used for demonstration purposes only. If you need further information about the creation of a Kafka topic, see Apache's documentation for Kafka./usr/lib/kafka/bin/kafka-topics.sh --zookeeper localhost:2181 --create --topic activities --partitions 1 --replication-factor 1
This command creates a topic named activities, using the Kafka brokers managed by the Zookeeper service on the localhost machine.

Publish the message you want to analyze to the activities topic you have just created. In this scenario, Kafka is used to perform this publication using, for example, the following command:

echo 'Ryan|M|Pool
Remy|M|Drink
Remy|M|Hiking
Irene|F|Drink
Pierre|M|Movie
Irene|F|Pool
Thomas|M|Drink
Ryan|M|Cooking
Wang|F|Cooking
Chen|M|Drink | /usr/lib/kafka/bin/kafka-console-producer.sh --broker-list  localhost:9092 --topic  activities

This command publishes 10 simple messages

Ryan|M|Pool
Remy|M|Drink
Remy|M|Hiking
Irene|F|Drink
Pierre|M|Movie
Irene|F|Pool
Thomas|M|Drink
Ryan|M|Cooking
Wang|F|Cooking
Chen|M|Drink

As explained previously, you can use your actual message producer system instead to perform the publication.
