Book Description
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

Book Description
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.

"Tarot archetypes provide the reader with a window into present circumstances and future potential. But what if that window only opened up on a world that was white, European, and heterosexual? This book explores themes of sexuality, coming out, gender and gender-queering, sources of oppression and empowerment, and many other topics especially familiar to "not-straight" folks"--

Book Description
Follow this handbook to build, configure, tune, and secure Apache Cassandra databases. Start with the installation of Cassandra and move on to the creation of a single instance, and then a cluster of Cassandra databases. Cassandra is increasingly a key player in many big data environments, and this book shows you how to use Cassandra with Apache Spark, a popular big data processing framework. Also covered are day-to-day topics of importance such as the backup and recovery of Cassandra databases, using the right compression and compaction strategies, and loading and unloading data. Expert Apache Cassandra Administration provides numerous step-by-step examples starting with the basics of a Cassandra database, and going all the way through backup and recovery, performance optimization, and monitoring and securing the data. The book serves as an authoritative and comprehensive guide to the building and management of simple to complex Cassandra databases. The book: Takes you through building a Cassandra database from installation of the software and creation of a single database, through to complex clusters and data centers Provides numerous examples of actual commands in a real-life Cassandra environment that show how to confidently configure, manage, troubleshoot, and tune Cassandra databases Shows how to use the Cassandra configuration properties to build a highly stable, available, and secure Cassandra database that always operates at peak efficiency What You'll Learn Install the Cassandra software and create your first database Understand the Cassandra data model, and the internal architecture of a Cassandra database Create your own Cassandra cluster, step-by-step Run a Cassandra cluster on Docker Work with Apache Spark by connecting to a Cassandra database Deploy Cassandra clusters in your data center, or on Amazon EC2 instances Back up and restore mission-critical Cassandra databases Monitor, troubleshoot, and tune production Cassandra databases, and cut your spending on resources such as memory, servers, and storage Who This Book Is For Database administrators, developers, and architects who are looking for an authoritative and comprehensive single volume for all their Cassandra administration needs. Also for administrators who are tasked with setting up and maintaining highly reliable and high-performing Cassandra databases.
