Scalable Data Architecture with Java

By: Sinchan Banerjee

Overview of this book

Java architectural patterns and tools help architects to build reliable, scalable, and secure data engineering solutions that collect, manipulate, and publish data. This book will help you make the most of the architecting data solutions available with clear and actionable advice from an expert. You’ll start with an overview of data architecture, exploring responsibilities of a Java data architect, and learning about various data formats, data storage, databases, and data application platforms as well as how to choose them. Next, you’ll understand how to architect a batch and real-time data processing pipeline. You’ll also get to grips with the various Java data processing patterns, before progressing to data security and governance. The later chapters will show you how to publish Data as a Service and how you can architect it. Finally, you’ll focus on how to evaluate and recommend an architecture by developing performance benchmarks, estimations, and various decision metrics. By the end of this book, you’ll be able to successfully orchestrate data architecture solutions using Java and related technologies as well as to evaluate and present the most suitable solution to your clients.

Federated and Scalable DaaS with GraphQL

In the previous chapter, we discussed how to publish ingested data in a format that is platform- and language-agnostic using the REST API. We also learned how to design and develop a Data as a Service (DaaS) layer using the REST API, as well as how to containerize and deploy the application on AWS ECS. Then, we learned what an API management system is and how it can help monitor and manage APIs more efficiently. Finally, we learned how to create an API management layer on top of our REST DaaS application using Amazon API Gateway.

In this chapter, we will learn how to implement DaaS using GraphQL instead of REST. To do so, we will learn what GraphQL is, and why and when it should be used. We will explore the benefits and shortcomings that GraphQL has concerning REST while discussing the various architectural patterns available for GraphQL-based solutions. Finally, we will learn about the power of federation in the GraphQL layer. By the end...
