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.

Creating a DaaS to expose data using Spring Boot

In this section, we will learn how to expose a REST-based DaaS API using Java and Spring Boot. But before we try to create the solution, we must understand the problem that we are going to solve.

Important note

REST stands for Representational State Transfer. It is not a protocol or standard; instead, it provides certain architectural constraints to expose the data layer. The REST API allows you to transfer the representational state of a data resource to the REST endpoint. These representations can be in JSON, XML, HTML, XLT, or plain text format so that they can be transferred over the HTTP/(S) protocol.

Problem statement

In the solution described in Chapter 6, Architecting a Real-Time Processing Pipeline, we analyzed and ingested analytical data in a MongoDB-based collection. Now, we want to expose the documents present in the collection using a DaaS service that can be searched for by either ApplicationId or CustomerId...
