Imagine what you could do if scalability wasn't a problem. With this hands-on guide, you’ll learn how the Cassandra database management system handles hundreds of terabytes of data while remaining highly available across multiple data centers. This expanded second edition—updated for Cassandra 3.0—provides the technical details and practical examples you need to put this database to work in a production environment. Authors Jeff Carpenter and Eben Hewitt demonstrate the advantages of Cassandra’s non-relational design, with special attention to data modeling. If you’re a developer, DBA, or application architect looking to solve a database scaling issue or future-proof your application, this guide helps you harness Cassandra’s speed and flexibility. Understand Cassandra’s distributed and decentralized structure Use the Cassandra Query Language (CQL) and cqlsh—the CQL shell Create a working data model and compare it with an equivalent relational model Develop sample applications using client drivers for languages including Java, Python, and Node.js Explore cluster topology and learn how nodes exchange data Maintain a high level of performance in your cluster Deploy Cassandra on site, in the Cloud, or with Docker Integrate Cassandra with Spark, Hadoop, Elasticsearch, Solr, and Lucene

Adaptivity and learning have in recent decades become a common concern of scientific disciplines. These issues have arisen in mathematics, physics, biology, informatics, economics, and other fields more or less simultaneously. The aim of this publication is the interdisciplinary discourse on the phenomenon of learning and adaptivity. Different perspectives are presented and compared to find fruitful concepts for the disciplines involved. The authors select problems showing representative traits concerning the frame up, the methods and the achievements rather than to present extended overviews.

Why a book on fault-tolerant search algorithms? Searching is one of the fundamental problems in computer science. Time and again algorithmic and combinatorial issues originally studied in the context of search find application in the most diverse areas of computer science and discrete mathematics. On the other hand, fault-tolerance is a necessary ingredient of computing. Due to their inherent complexity, information systems are naturally prone to errors, which may appear at any level – as imprecisions in the data, bugs in the software, or transient or permanent hardware failures. This book provides a concise, rigorous and up-to-date account of different approaches to fault-tolerance in the context of algorithmic search theory. Thanks to their basic structure, search problems offer insights into how fault-tolerant techniques may be applied in various scenarios. In the first part of the book, a paradigmatic model for fault-tolerant search is presented, the Ulam—Rényi problem. Following a didactic approach, the author takes the reader on a tour of Ulam—Rényi problem variants of increasing complexity. In the context of this basic model, fundamental combinatorial and algorithmic issues in the design of fault-tolerant search procedures are discussed. The algorithmic efficiency achievable is analyzed with respect to the statistical nature of the error sources, and the amount of information on which the search algorithm bases its decisions. In the second part of the book, more general models of faults and fault-tolerance are considered. Special attention is given to the application of fault-tolerant search procedures to specific problems in distributed computing, bioinformatics and computational learning. This book will be of special value to researchers from the areas of combinatorial search and fault-tolerant computation, but also to researchers in learning and coding theory, databases, and artificial intelligence. Only basic training in discrete mathematics is assumed. Parts of the book can be used as the basis for specialized graduate courses on combinatorial search, or as supporting material for a graduate or undergraduate course on error-correcting codes.

What story would Eve have told about picking the apple? Why is Pandora blamed for opening the box? And what about the fate of Cassandra who was blessed with knowing the future but cursed so that no one believed her? What if women had been the storytellers? Elizabeth Lesser believes that if women’s voices had been equally heard and respected throughout history, humankind would have followed different hero myths and guiding stories—stories that value caretaking, champion compassion, and elevate communication over vengeance and violence. Cassandra Speaks is about the stories we tell and how those stories become the culture. It’s about the stories we still blindly cling to, and the ones that cling to us: the origin tales, the guiding myths, the religious parables, the literature and films and fairy tales passed down through the centuries about women and men, power and war, sex and love, and the values we live by. Stories written mostly by men with lessons and laws for all of humanity. We have outgrown so many of them, and still they endure. This book is about what happens when women are the storytellers too—when we speak from our authentic voices, when we flex our values, when we become protagonists in the tales we tell about what it means to be human. Lesser has walked two main paths in her life—the spiritual path and the feminist one—paths that sometimes cross but sometimes feel at cross-purposes. Cassandra Speaks is her extraordinary merging of the two. The bestselling author of Broken Open and Marrow, Lesser is a beloved spiritual writer, as well as a leading feminist thinker. In this book she gives equal voice to the cool water of her meditative self and the fire of her feminist self. With her trademark gifts of both humor and insight, she offers a vision that transcends the either/or ideologies on both sides of the gender debate. Brilliantly structured into three distinct parts, Part One explores how history is carried forward through the stories a culture tells and values, and what we can do to balance the scales. Part Two looks at women and power and expands what it means to be courageous, daring, and strong. And Part Three offers “A Toolbox for Inner Strength.” Lesser argues that change in the culture starts with inner change, and that no one—woman or man—is immune to the corrupting influence of power. She provides inner tools to help us be both strong-willed and kind-hearted. Cassandra Speaks is a beautifully balanced synthesis of storytelling, memoir, and cultural observation. Women, men and all people will find themselves in the pages of this book, and will come away strengthened, opened, and ready to work together to create a better world for all people.
