Summary
In this chapter, as with any other chapter in this part of the book, we started with introducing the layer where the technology would fall. Then we introduced the chosen technology in this layer, namely Apache Flink. We slowly went into the details of Apache Flink. Its architecture was elaborated and many core aspects of this all-important framework were covered in brief. We then got our hands dirty with an actual implementation of Apache Flink technology pertaining to our use case--SCV. We finally explained when to use and when not to use Flink, and closed the chapter with alternatives to Apache Flink.
After reading this chapter, you should have a fair idea of the Data Ingestion layer and the full working and functioning of Apache Flink. Now you also know about Flink’s architecture along with its core components and working. You should have also got hands-on working experience with Flink and a high-level view of the alternatives to Flink.
