Build real-world, industry-strength data storage solutions with time-tested design methodologies using CassandraAbout This BookExplore design patterns which co-exist with legacy data stores, migration from RDBMS, and caching technologies with CassandraLearn about design patterns and use Cassandra to provide consistency, availability, and partition tolerance guarantees for applicationsHandle temporal data for analytical purposes Who This Book Is For This book is intended for big data developers who are familiar with the basics of Cassandra and wish to understand and utilize Cassandra design patterns to develop real-world big data solutions. Prior knowledge of RDBMS solutions is assumed.What You Will LearnEnable Cassandra to co-exist with RDBMS and other legacy data storesExplore various design patterns to build effective and robust storage solutionsMigrate from RDBMS-based data stores and caching solutions to CassandraUnderstand the behaviour of Cassandra when trying to balance the needs of consistency, availability, and partition toleranceDeal with time stamps related to data effectivelySee how Cassandra can be used in analytical use casesApply the design patterns covered in this book in real-world use cases In Detail There are many NoSQL data stores used by big data applications. Cassandra is one of the most widely used NoSQL data stores that is frequently used by a huge number of heavy duty Internet-scale applications. Unlike the RDBMS world, the NoSQL landscape is very diverse and there is no one way to model data stores. This mandates the need to have good solutions to commonly seen data store design problems. Cassandra addresses such common problems simply. If you are new to Cassandra but well-versed in RDBMS modeling and design, then it is natural to model data in the same way in Cassandra, resulting in poorly performing applications and losing the real purpose of Cassandra. If you want to learn to make the most of Cassandra, this book is for you. This book starts with strategies to integrate Cassandra with other legacy data stores and progresses to the ways in which a migration from RDBMS to Cassandra can be accomplished. The journey continues with ideas to migrate data from cache solutions to Cassandra. With this, the stage is set and the book moves on to some of the most commonly seen problems in applications when dealing with consistency, availability, and partition tolerance guarantees. Cassandra is exceptionally good at dealing with temporal data and patterns such as the time-series pattern and log pattern, which are covered next. Many NoSQL data stores fail miserably when a huge amount of data is read for analytical purposes, but Cassandra is different in this regard. Keeping analytical needs in mind, you’ll walk through different and interesting design patterns. No theoretical discussions are complete without a good set of use cases to which the knowledge gained can be applied, so the book concludes with a set of use cases you can apply the patterns you’ve learned.Style and approach This book is written in very simple language and an engaging style complete with examples in every chapter and real-world use cases at the end of the book.

Why do people who have dogs live happier, longer, and more fulfulling livesSociologists and veterinarians have spent years investigating the positive effects that dogs have on people's health and happiness yet their findings are inaccessible to ordinary people, hidden in obscure journals to be shared with other experts. Now the international bestselling author of the 100 Simple Secrets series has collected the most current and significant data from more than a thousand of the best scientific studies on the profound relationship between humans and our canine companions. These findings have been boiled down to the one hundred essential ways dogs positively impact our lives. Each fact is accompanied by a inspiring true story. If you love your dog, and science tells us that you do, this book will inspire and entertain. Communicate Better: It sounds odd to say a creature that communicates with barking and body language can have such a profound effect on human communication. But by providing a common point of reference and concern, dogs help us to feel a connection to other humans. That connection makes us feel more comfortable communicating with each other. When meeting a new person, the presence of a dog reduces the time before people feel comfortable while talking with each other by 45 percent. Live Longer: There is perhaps no better gift that dogs offer us humans than this simple fact. People who care for a dog live longer, healthier lives than those who do not. On average, people who cared for dogs during their lives lived 3 years longer than people who never had a dog. No Monkey Business: Primates are genetically more similar to humans than any other creature. But try to tell a chimpanzee something and you will be hard pressed to get your message across. Dogs are uniquely attuned to the messages we send. Dogs study humans and have evolved to build social skills that help them to function around us. Dogs are 52 percent more likely to follow human cues such as pointing toward a source of food than are primates. Around the Block: Good habits are often misunderstood as difficult or unpleasant chores. But there is tremendous value in the simple act of taking a walk. Walking not only burns calories, it also decreases stress. Having a dog means regularly talking walks it's something you do for your dog but in truth your dog is doing for you. Dog owners walk 79 percent farther in an average week than non–dog owners.
