Configuring Kafka Topics

Kafka topics are highly configurable, allowing you to customize their behavior in a variety of ways. In this hands-on lab, you will have the opportunity to work with Kafka configurations by making some changes to the configuration of an existing topic. You will also work with global broker configuration by changing some default topic configuration values that will be used for new topics.
