Kafka Console Consumer Command Line Interface (CLI)

The video tutorial explains how to use the Kafka console consumer to read messages from a Kafka topic. It covers the setup of the console consumer, the behavior of message consumption, and how to produce messages using the console producer. The tutorial also demonstrates how to read all messages from a topic by using the 'from beginning' option, allowing users to access both historical and new messages. The session concludes with a brief mention of the next lecture, which will cover using the console consumer in consumer group mode.

What is the next topic to be covered after the basics of the console consumer?

• Advanced Kafka producer techniques
