This was a complete review of Apache Kafka and we have touched upon many important facts about it. We have also learned the reason why Kafka was developed, Kafka installation, and its support for different types of clusters. We also explored Kafka's design approach, and wrote a few basic producers and consumers.
In this chapter, we learned how to set up a Kafka cluster with single and multiple brokers on a single node, run producers and consumers from the command line, and exchange some messages. We also discussed important settings about the broker. Finally, we discussed Kafka's integration with technologies such as Spark.
In the next chapter we will review some integration patterns with examples. Take a look at Chapter 7, Study Case 1 - Spark and Cassandra, where we take a look at an in-depth example of Kafka integration with the other technologies.
