Overview of this book

Scala Programming Projects is a comprehensive project-based introduction for those who are new to Scala. Complete with step-by-step instructions and easy-to-follow tutorials that demonstrate best practices when building applications, this Scala book will have you building real-world projects in no time. Starting with the fundamentals of software development, you’ll begin with simple projects, such as developing a financial independence calculator, and then advance to more complex projects, such as a building a shopping application and a Bitcoin transaction analyzer. You’ll explore a variety of Scala features, including its OOP and FP capabilities, and learn how to write concise, reactive, and concurrent applications in a type-safe manner. You’ll also understand how to use libraries such as Akka and Play. Furthermore, you’ll be able to integrate your Scala apps with Kafka, Spark, and Zeppelin, along with deploying applications on a cloud platform. By the end of the book, you’ll have a firm foundation in Java programming that’ll enable you to solve a variety of real-world problems, and you’ll have built impressive projects to add to your professional portfolio.

Introducing Apache Kafka


In the previous section, Introducing Lambda Architecture, we mentioned that Kafka is used for stream processing. Apache Kafka is a high throughput distributed messaging system. It allows decoupling the data coming in with the data going out.

It means that multiple systems (producers) can send messages to Kafka. Kafka will then deliver these messages out to the consumers registered.

Kafka is distributed, resilient, and fault-tolerant, and has a very low latency. Kafka can scale horizontally by adding more machines to the system. It is written in Scala and Java.

Kafka is broadly used; Airbnb, Netflix, Uber, and LinkedIn use this technology.

The purpose of this chapter is not to become an expert in Kafka, but rather to familiarize you with the fundamentals of this technology. By the end of the chapter, you will be able to understand the use case developed in this chapter—streaming bitcoin transactions in a Lambda architecture.
