Summary
The topic covered in this chapter is quite exhaustive. Rest assured that you have covered enough of Apache Kafka to implement a Data Lake.
In this chapter, we started with the relevance of messaging layer in the context of a Data Lake. After that, the chapter deep dived into Kafka and detailed it's architecture and its various components. It then showed you the full working example of Kafka with step-by-step instructions from installation all the way to taking data from a source, to destination using Kafka. Finally, as in other chapters we introduced other choices which can replace Kafka as the technology to achieve the same capability.
After reading this chapter, you should now have a clear idea of the messaging layer and a deep understanding of Apache Kafka and how it works. You should also have a clear idea of how our use case can use this technology and what exactly it accomplishes.
