Use this practical guide to successfully handle the challenges encountered when designing an enterprise data lake and learn industry best practices to resolve issues. When designing an enterprise data lake you often hit a roadblock when you must leave the comfort of the relational world and learn the nuances of handling non-relational data. Starting from sourcing data into the Hadoop ecosystem, you will go through stages that can bring up tough questions such as data processing, data querying, and security. Concepts such as change data capture and data streaming are covered. The book takes an end-to-end solution approach in a data lake environment that includes data security, high availability, data processing, data streaming, and more. Each chapter includes application of a concept, code snippets, and use case demonstrations to provide you with a practical approach. You will learn the concept, scope, application, and starting point. What You'll Learn

A practical guide to help you tackle different real-time data processing and analytics problems using the best tools for each scenarioAbout This Book<ul>
<li>Learn about the various challenges in real-time data processing and use the right tools to overcome them</li>
<li>This book covers popular tools and frameworks such as Spark, Flink, and Apache Storm to solve all your distributed processing problems</li>
<li>A practical guide filled with examples, tips, and tricks to help you perform efficient Big Data processing in real-time</li>
</ul>Who This Book Is ForIf you are a Java developer who would like to be equipped with all the tools required to devise an end-to-end practical solution on real-time data streaming, then this book is for you. Basic knowledge of real-time processing would be helpful, and knowing the fundamentals of Maven, Shell, and Eclipse would be great.What You Will Learn<ul>
<li>Get an introduction to the established real-time stack</li>
<li>Understand the key integration of all the components</li>
<li>Get a thorough understanding of the basic building blocks for real-time solution designing</li>
<li>Garnish the search and visualization aspects for your real-time solution</li>
<li>Get conceptually and practically acquainted with real-time analytics</li>
<li>Be well equipped to apply the knowledge and create your own solutions</li>
</ul>In DetailWith the rise of Big Data, there is an increasing need to process large amounts of data continuously, with a shorter turnaround time. Real-time data processing involves continuous input, processing and output of data, with the condition that the time required for processing is as short as possible.
This book covers the majority of the existing and evolving open source technology stack for real-time processing and analytics. You will get to know about all the real-time solution aspects, from the source to the presentation to persistence. Through this practical book, you’ll be equipped with a clear understanding of how to solve challenges on your own.
We’ll cover topics such as how to set up components, basic executions, integrations, advanced use cases, alerts, and monitoring. You’ll be exposed to the popular tools used in real-time processing today such as Apache Spark, Apache Flink, and Storm. Finally, you will put your knowledge to practical use by implementing all of the techniques in the form of a practical, real-world use case.
By the end of this book, you will have a solid understanding of all the aspects of real-time data processing and analytics, and will know how to deploy the solutions in production environments in the best possible manner.Style and Approach In this practical guide to real-time analytics, each chapter begins with a basic high-level concept of the topic, followed by a practical, hands-on implementation of each concept, where you can see the working and execution of it. The book is written in a DIY style, with plenty of practical use cases, well-explained code examples, and relevant screenshots and diagrams.

This book examines the politics of rural development with special reference to watershed development interventions in the desert province of Rajasthan in India. Watershed development (and rainwater harvesting) is one of the most significant rural development interventions in rainfed areas of India since the early 1990s. A range of developmental actors including the state watershed department, international donors, NGOs and grassroots organisations are involved in sponsoring watershed development projects. Using multi-sited ethnography and conversational interviews with the deliverers as well as recipients of development, the book compares and contrasts the watershed interventions of the state and two different kinds of NGOs in Rajasthan. While conventional studies on watershed development have focused on the evaluation of ‘success’ or ‘failure’ of particular projects, whether implemented by the state or NGOs, the book moves beyond this narrow analytical gaze to look at the roles, agendas and interests of multiple development agencies, often partnering together and sometimes competing with each other as part of, what the author calls, the ‘watershed development regime’.Taking cue from watershed development and water conservation projects over the last two decades, the book engages with the larger question of ‘how’ of delivering development. It examines the complex processes of cooperation, competition, negotiations, contestations and conflicts between different stakeholders, including the agents of development and differently positioned rural social groups in the context of Rajasthan. The book demonstrates that the recent interventions in watershed development and rainwater harvesting have considerably shaped the politics of development in Rajasthan in a number of ways: by becoming a site for the remaking of the ‘state’ and its internal relations, by disturbing the local hegemony in the countryside, by creating new relations of patronage between diverse agents and recipients of development, by increasing the associational capacity as well as creating new conflicts (intra and inter village) and by initiating competition and cooperation between the various agents of development over control of local resources and power.

Over the last couple of decades, there has been tremendous use of information technology in business. Business leaders cite training end-users to use technology as a one of the key challenges of the future. This book explores three contemporary methods in end-user training: e-learning, peer collaboration and collaborative e-learning. Drawing on the two foundational disciplines of Information Systems and Education, this book first summarizes the inconsistencies in existing literature. Next, it outlines a theoretical model that describes the effect of learning methods using the structures embedded in the technology, teams and techniques as well as the important role of faithful appropriation of learning methods on learning outcomes. Finally, drawing on the results of a 2X2 multi-period quasi-experiment, the book outlines detailed guidelines for researchers and practitioners in the area of End-user training as well as anyone else involved in the area of training.
