A practical guide to implementing your enterprise data lake using Lambda Architecture as the base About This Book * Build a full-fledged data lake for your organization with popular big data technologies using the Lambda architecture as the base * Delve into the big data technologies required to meet modern day business strategies * A highly practical guide to implementing enterprise data lakes with lots of examples and real-world use-cases Who This Book Is For Java developers and architects who would like to implement a data lake for their enterprise will find this book useful. If you want to get hands-on experience with the Lambda Architecture and big data technologies by implementing a practical solution using these technologies, this book will also help you. What You Will Learn * Build an enterprise-level data lake using the relevant big data technologies * Understand the core of the Lambda architecture and how to apply it in an enterprise * Learn the technical details around Sqoop and its functionalities * Integrate Kafka with Hadoop components to acquire enterprise data * Use flume with streaming technologies for stream-based processing * Understand stream- based processing with reference to Apache Spark Streaming * Incorporate Hadoop components and know the advantages they provide for enterprise data lakes * Build fast, streaming, and high-performance applications using ElasticSearch * Make your data ingestion process consistent across various data formats with configurability * Process your data to derive intelligence using machine learning algorithms In Detail The term "Data Lake" has recently emerged as a prominent term in the big data industry. Data scientists can make use of it in deriving meaningful insights that can be used by businesses to redefine or transform the way they operate. Lambda architecture is also emerging as one of the very eminent patterns in the big data landscape, as it not only helps to derive useful information from historical data but also correlates real-time data to enable business to take critical decisions. This book tries to bring these two important aspects - data lake and lambda architecture-together. This book is divided into three main sections. The first introduces you to the concept of data lakes, the importance of data lakes in enterprises, and getting you up-to-speed with the Lambda architecture. The second section delves into the principal components of building a data lake using the Lambda architecture. It introduces you to popular big data technologies such as Apache Hadoop, Spark, Sqoop, Flume, and ElasticSearch. The third section is a highly practical demonstration of putting it all together, and shows you how an enterprise data lake can be implemented, along with several real-world use-cases. It also shows you how other peripheral components can be added to the lake to make it more efficient. By the end of this book, you will be able to choose the right big data technologies using the lambda architectural patterns to build your enterprise data lake. Style and approach The book takes a pragmatic approach, showing ways to leverage big data technologies and lambda architecture to build an enterprise-level data lake.

The Chronicles of Devi is an eternal story... The celebration of triumph of a single woman and her lion over the forces of evil. A story which celebrates the power of a unique woman who could create life as well as destroy to save her creation.
Billions of years ago, a wonderful experiment started on planet Bhuvan when a celestial woman, DEVI puffed life on Bhuvan. As Bhuvan rotated on its axis, the celestial rondures churned to create three worlds on it. The radiant white orbs created the upper-earth called Swarg, the warm green orbs created the middle-earth Dharti and dark black orbs created under-earth Patal. In their final moments, each rondure expanded till it burst open like a seed pod and revealed a fully developed yet "sui generis" life form.
Devi had not imagined that her creations would spawn so rapidly and be so quickly consumed by their own lust, greed, gluttony, pride, and envy to a degree that would threaten the very existence of the planet, Bhuvan, also called Earth, that nurtured them. She knew that the intelligence she imparted to the humans was a double edged sword-one that could be used to deepen their knowledge beyond known realms, but at the same time could annihilate its user if in wrong hands. Devi knew this before she sparked the helix of human life. She smiled knowingly as she did it, but she wanted to see how the humans dealt with the issue of right and wrong when they encountered it amongst their own kind. It was an experiment for her to create bigger universes.
Today she was amused, but even more irritated. The world that she had created with such love was facing a threat to its survival. Such was the irony that the very hands which rose toward her begging for help, and the hands which ominously threatened to chop them off, all belonged to her own children.
But Devi had no doubt in her mind. She knew how to pacify them both. A motherly glance which can soothe even the most troubled heart instantaneously, or a swift blow to knock one senseless-both of these were at her command and she would not hesitate to use them. Mahisha need to be taught a lesson. Attempting to become the new lord of universe, the fool was not only attempting to challenge Devi's own authority but was also tormenting others to an unconscionable degree.
And then Devi came to Bhuvan in the form of Mahalakshmi.
A woman and her lion who became a legend,
Together they fought, to vanquish the evil on Bhuvan and restore the balance of nature,
Read the book for an exhilarating journey of creation of life, an unprecedented cataclysm and the ultimate triumph.

The story of an epic adventure in the second book of The Chronicles Of Devi series. One thousand years had passed since planet Bhuvan was rid of evil Mahisha by Devi's incarnation, Mahalakshmi, and life on Bhuvan was flourishing. But in the Asur Empire, which flourished in under-earth Patal, some were not happy. Although many, many years had passed since their ancestors witnessed the vanquishing of Mahisha, they had still not reconciled themselves to defeat at the hands of Devi and the subsequent handing over of power to the Devas. Stirrings of revenge were resurging in the hearts of the Asurs. Deep within them a hungry desire to once again be the supreme lords of Bhuvan still lived and flourished. In the beautiful gardens of under-earth Patal, the handsome Danava princes, Shumbh and Nishumbh plan their strategy. But, the biggest obstacle to their plans was Devi. She again takes form. A woman and her lion who return to planet Bhuvan and establish the rule of law. Centuries pass but the legend lives on.
