Apache Ignite Quick Start Guide

By: Sujoy Acharya

Overview of this book

Apache Ignite is a distributed in-memory platform designed to scale and process large volume of data. It can be integrated with microservices as well as monolithic systems, and can be used as a scalable, highly available and performant deployment platform for microservices. This book will teach you to use Apache Ignite for building a high-performance, scalable, highly available system architecture with data integrity. The book takes you through the basics of Apache Ignite and in-memory technologies. You will learn about installation and clustering Ignite nodes, caching topologies, and various caching strategies, such as cache aside, read and write through, and write behind. Next, you will delve into detailed aspects of Ignite’s data grid: web session clustering and querying data. You will learn how to process large volumes of data using compute grid and Ignite’s map-reduce and executor service. You will learn about the memory architecture of Apache Ignite and monitoring memory and caches. You will use Ignite for complex event processing, event streaming, and the time-series predictions of opportunities and threats. Additionally, you will go through off-heap and on-heap caching, swapping, and native and Spring framework integration with Apache Ignite. By the end of this book, you will be confident with all the features of Apache Ignite 2.x that can be used to build a high-performance system architecture.

Getting Familiar with Apache Ignite

As software practitioners, we review different technologies and frameworks. They are nothing but a tool. A toolbox contains many tools for different purposes. The challenge for us while picking a tool is to know which is the right one to apply to the situation. If we pick up a hammer and try to use it for everything, we will probably end up with a mess. The art of designing software is knowing its purpose, and when to use each tool. Apache Ignite adds another tool to our toolbox that we can pick up when the right situation arises. When you learn a new concept or framework, you should always ask: why do I need a new framework?

The why explains the purpose, how tells you about the process, and what talks about the result of why.

As technologists, we can adhere to Simon Sinek's Golden Circle theory that people don't buy what you do, they buy why you do it. Our clients don't care about our technology stack, they care about business functionalities.

Let's explore the why of Apache Ignite. The following topics are covered in this chapter:

  • Why Apache Ignite?
  • Exploring the features
  • Refactoring the architecture
  • Installing Apache Ignite
  • Running HelloWorld
  • Classifying Apache Ignite
