Opis: Data Just Right - Michael Manoochehri

Making Big Data Work: Real-World Use Cases and Examples, Practical Code, Detailed Solutions Large-scale data analysis is now vitally important to virtually every business. Mobile and social technologies are generating massive datasets; distributed cloud computing offers the resources to store and analyze them; and professionals have radically new technologies at their command, including NoSQL databases. Until now, however, most books on "Big Data" have been little more than business polemics or product catalogs. Data Just Right is different: It's a completely practical and indispensable guide for every Big Data decision-maker, implementer, and strategist. Michael Manoochehri, a former Google engineer and data hacker, writes for professionals who need practical solutions that can be implemented with limited resources and time. Drawing on his extensive experience, he helps you focus on building applications, rather than infrastructure, because that's where you can derive the most value. Manoochehri shows how to address each of today's key Big Data use cases in a cost-effective way by combining technologies in hybrid solutions. You'll find expert approaches to managing massive datasets, visualizing data, building data pipelines and dashboards, choosing tools for statistical analysis, and more. Throughout, the author demonstrates techniques using many of today's leading data analysis tools, including Hadoop, Hive, Shark, R, Apache Pig, Mahout, and Google BigQuery. Coverage includes * Mastering the four guiding principles of Big Data success-and avoiding common pitfalls * Emphasizing collaboration and avoiding problems with siloed data * Hosting and sharing multi-terabyte datasets efficiently and economically * "Building for infinity" to support rapid growth * Developing a NoSQL Web app with Redis to collect crowd-sourced data * Running distributed queries over massive datasets with Hadoop, Hive, and Shark * Building a data dashboard with Google BigQuery * Exploring large datasets with advanced visualization * Implementing efficient pipelines for transforming immense amounts of data * Automating complex processing with Apache Pig and the Cascading Java library * Applying machine learning to classify, recommend, and predict incoming information * Using R to perform statistical analysis on massive datasets * Building highly efficient analytics workflows with Python and Pandas * Establishing sensible purchasing strategies: when to build, buy, or outsource * Previewing emerging trends and convergences in scalable data technologies and the evolving role of the Data ScientistForeword xv Preface xvii Acknowledgments xxv About the Author xxvii Part I: Directives in the Big Data Era 1 Chapter 1: Four Rules for Data Success 3 When Data Became a BIG Deal 3 Data and the Single Server 4 The Big Data Trade-Off 5 Anatomy of a Big Data Pipeline 9 The Ultimate Database 10 Summary 10 Part II: Collecting and Sharing a Lot of Data 11 Chapter 2: Hosting and Sharing Terabytes of Raw Data 13 Suffering from Files 14 Storage: Infrastructure as a Service 15 Choosing the Right Data Format 16 Character Encoding 19 Data in Motion: Data Serialization Formats 21 Summary 23 Chapter 3: Building a NoSQL-Based Web App to Collect Crowd-Sourced Data 25 Relational Databases: Command and Control 25 Relational Databases versus the Internet 28 Nonrelational Database Models 31 Leaning toward Write Performance: Redis 35 Sharding across Many Redis Instances 38 NewSQL: The Return of Codd 41 Summary 42 Chapter 4: Strategies for Dealing with Data Silos 43 A Warehouse Full of Jargon 43 Hadoop: The Elephant in the Warehouse 48 Data Silos Can Be Good 49 Convergence: The End of the Data Silo 51 Summary 53 Part III: Asking Questions about Your Data 55 Chapter 5: Using Hadoop, Hive, and Shark to Ask Questions about Large Datasets 57 What Is a Data Warehouse? 57 Apache Hive: Interactive Querying for Hadoop 60 Shark: Queries at the Speed of RAM 65 Data Warehousing in the Cloud 66 Summary 67 Chapter 6: Building a Data Dashboard with Google BigQuery 69 Analytical Databases 69 Dremel: Spreading the Wealth 71 BigQuery: Data Analytics as a Service 73 Building a Custom Big Data Dashboard 75 The Future of Analytical Query Engines 82 Summary 83 Chapter 7: Visualization Strategies for Exploring Large Datasets 85 Cautionary Tales: Translating Data into Narrative 86 Human Scale versus Machine Scale 89 Building Applications for Data Interactivity 90 Summary 96 Part IV: Building Data Pipelines 97 Chapter 8: Putting It Together: MapReduce Data Pipelines 99 What Is a Data Pipeline? 99 Data Pipelines with Hadoop Streaming 101 A One-Step MapReduce Transformation 105 Managing Complexity: Python MapReduce Frameworks for Hadoop 110 Summary 114 Chapter 9: Building Data Transformation Workflows with Pig and Cascading 117 Large-Scale Data Workflows in Practice 118 It's Complicated: Multistep MapReduce Transformations 118 Cascading: Building Robust Data-Workflow Applications 122 When to Choose Pig versus Cascading 128 Summary 128 Part V: Machine Learning for Large Datasets 129 Chapter 10: Building a Data Classification System with Mahout 131 Can Machines Predict the Future? 132 Challenges of Machine Learning 132 Apache Mahout: Scalable Machine Learning 136 MLBase: Distributed Machine Learning Framework 139 Summary 140 Part VI: Statistical Analysis for Massive Datasets 143 Chapter 11: Using R with Large Datasets 145 Why Statistics Are Sexy 146 Strategies for Dealing with Large Datasets 149 Summary 155 Chapter 12: Building Analytics Workflows Using Python and Pandas 157 The Snakes Are Loose in the Data Zoo 157 Python Libraries for Data Processing 160 Building More Complex Workflows 167 iPython: Completing the Scientific Computing Tool Chain 170 Summary 174 Part VII: Looking Ahead 177 Chapter 13: When to Build, When to Buy, When to Outsource 179 Overlapping Solutions 179 Understanding Your Data Problem 181 A Playbook for the Build versus Buy Problem 182 My Own Private Data Center 184 Understand the Costs of Open-Source 186 Everything as a Service 187 Summary 187 Chapter 14: The Future: Trends in Data Technology 189 Hadoop: The Disruptor and the Disrupted 190 Everything in the Cloud 191 The Rise and Fall of the Data Scientist 193 Convergence: The Ultimate Database 195 Convergence of Cultures 196 Summary 197 Index 199
