Learning Redis is meant to be a guide and handbook for developers, architects, solution providers, consultants, engineers, and anyone planning to learn, design, and architect an Enterprise Solution and looking for an in-memory datastore that is agile and fast and extends its capabilities beyond just storing data.
This book starts with an introduction to the evolving landscape of NoSQL, explores commands in easy-to-understand examples, and then uses Redis in a few sample applications, with Redis as the backbone. The later sections of the book focus on the management of Redis for performance and scalability.
This book covers core concepts to design and create fast, agile, and concurrent applications, but it is not meant to be a replacement for the official documentation guide for Redis, published by Redis.io.
Chapter 1, Introduction to NoSQL, covers the ecosystem of NoSQL. It discusses the evolution of the NoSQL landscape and provides an introduction to the various types of NoSQL and their characteristics.
Chapter 2, Getting Started with Redis, taps into the world of Redis. It also covers areas such as the installation of Redis on various platforms and running a sample program in Java to connect to Redis.
Chapter 3, Data Structures and Communicating Protocol in Redis, covers data structures that are available in Redis and the communicating protocol in Redis. It also covers examples that the user can execute and get a feel of using it. By the end of this chapter, you should have a basic feel of the capabilities of Redis.
Chapter 4, Functions in the Redis Server, takes you from learning commands to the various in-built capabilities of Redis. These capabilities include messaging in Redis, transactions, and the pipeline capabilities in Redis, which have differences between them. The chapter also introduces the users to a scripting language called LUA.
Chapter 5, Handling Data in Redis, focuses on the in-depth data handling capability of Redis. This includes the master-slave arrangement, the way data is stored in Redis, and various options it provides to persist data.
Chapter 6, Redis in Web Applications, is all about positioning Redis in web applications. To make it interesting, there are some example applications, which you can take ideas from, about the wide range of use cases where Redis can be used.
Chapter 7, Redis in Business Applications, is all about positioning Redis in business applications. To expand its applicability further in the Enterprise Solution design landscape, some example applications have been explained from which you can see its versatility.
Chapter 8, Clustering, talks about the clustering capability, how the end user can make use of various patterns in clustering for Redis, and use these patterns accordingly in their solutions.
Chapter 9, Maintaining Redis, is all about maintaining Redis in a production environment.
The following software is required for this book:
Redis
JDK 1.7
Jedis ( the Java client for Redis)
Eclipse, the IDE for development
This book is meant for developers, architects, solution providers, consultants, and engineers. Primarily the book requires knowledge of Java but it can also be understood by anybody with a bit of programming background.
Apart from this, there is information about how to design solutions and maintain them in production for which coding skills are not required.
In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.
Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The following code is for the new Hello World program, which is now called HelloWorld2:"
A block of code is set as follows:
package org.learningredis.chapter.two;
public class Helloworld2 {
JedisWrapper jedisWrapper = null;
public Helloworld2() {
jedisWrapper = new JedisWrapper();
}
private void test() {
jedisWrapper.set("MSG", "Hello world 2 ");
String result = jedisWrapper.get("MSG");
System.out.println("MSG : " + result);
}
public static void main(String[] args) {
Helloworld2 helloworld2 = new Helloworld2();
helloworld2.test();
}
}New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Note the last line showing on the Command Prompt: The servers now ready to accept connections on port 6379."
