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.

Core architectural patterns of GraphQL

In this section, we will discuss the various architectural patterns that are used for GraphQL. These patterns are independent of the technology used to implement it or the platform where it is deployed and executed. There are five different GraphQL patterns, as follows:

  • DaaS pattern: Here, GraphQL server is used to expose the database layer. It can expose three operations – queries, mutations, and subscriptions (please refer to the Operation types section of this chapter). Using these operations, it can achieve Create, Read, Update and Delete (CRUD) operations like REST but also supports subscriptions on top of it. The following diagram shows this pattern:

As we can see, GraphQL exposes its queries and operations using the HTTP protocol. GraphQL provides server libraries in multiple languages, using which teams can build and run GraphQL Server applications. Also, GraphQL...
