 Название: Indexing Beyond the Basics
Автор: Tobias Petry
Издательство: Independently published
Год: 2023
Язык: английский
Формат: pdf (true), epub
Размер: 20.7 MB
Learn to create indexes for your slow queries by following simple principles. Hi! I'm Tobias Petry, a full stack developer who used to suck at writing fast database queries. Whenever I had a slow query, I needed to ask more advanced developers for help and hope they had time for me. Like everyone, I always wished I could solve those problems on my own. But even after reading some tutorials I didn't get any closer to my goal. The number of queries I couldn't optimize by far exceeded the ones I could make faster. So I learned everything about databases over the next 10+ years from countless books, conferences, trainings, articles and much practice. Finally, I could fix any slow query entirely without help. But during my consulting work I found that most developers still face the same problem. The reason database indexes are still not understood by developers is the depth of the existing content. Whether it is books, articles or videos - they all have their own problems that limit the ability to understand database indexing. You are a developer who can write SQL queries but struggle with creating the correct indexes to make them fast. Neither do you have the time or interest to learn this topic in weeks - a couple evenings on the couch should be enough. You also just want to learn the practical knowledge necessary to complete your task and move on to other things. The content should avoid any technical complex database implementation details - you want the core information quickly, concisely and understandably. | |

 Название: BPF: профессиональная оценка производительности

Издательство: Питер
Год: 2024
Страниц: 880
Язык: русский
Формат: pdf
Размер: 12,2 MB
Инструменты оценки производительности на основе BPF дают беспрецедентную возможность анализа систем и приложений. Вы сможете улучшить производительность, устранить проблемы в коде, повысить безопасность и сократить расходы. Книга «BPF: профессиональная оценка производительности» — ваш незаменимый гайд по применению этих инструментов. Брендан Грегг — эксперт и пионер проекта BPF — представляет более 150 готовых инструментов анализа и отладки, рекомендации по их применению, а также пошаговые инструкции по разработке ваших собственных инструментов. Вы узнаете, как анализировать процессоры, память, дисковый ввод/вывод, файловую систему, сети, языки программирования, приложения, контейнеры, гипервизоры, безопасность и ядро. Вы сможете выработать глубокое понимание того, как улучшить буквально любую Linux-систему или приложение. Иногда программисты говорят, что они «стряпают патч» («cook a patch»), а не «реализуют» (implement). Я начал увлекаться программированием еще в школе. Чтобы получить хороший код, программист должен выбрать лучшие «ингредиенты». Разные языки программирования предлагают множество разных строительных блоков — «ингредиентов», но когда дело доходит до программирования ядра Linux, то кроме самого ядра у вас ничего нет. В ядре Linux уже был похожий механизм, известный как BPF (Berkeley Packet Filter — пакетный фильтр Беркли), поддерживавший минимальный набор команд, которые можно использовать для фильтрации пакетов перед передачей их приложениям, таким как tcpdump. | |

 Название: Getting Started with Enterprise Architecture: A Practical and Pragmatic Approach to Learning the Basics of Enterprise Architecture
Автор: Eric Jager
Издательство: Apress
Год: 2023
Страниц: 280
Язык: английский
Формат: pdf
Размер: 10.2 MB
Implement a basic enterprise architecture from start to finish using a four stage wheel-based approach. Aided by real-world examples, this book shows what elements are needed for the initial implementation of a fundamental enterprise architecture. The book's pragmatic approach keeps existing architecture frameworks and methodologies in mind while providing instructions that are readable and applicable to all. The Enterprise Architecture Implementation Wheel builds on the methodology of existing architecture frameworks and allows you to apply the theory more pragmatically and closer to the reality that an architect encounters in daily practice. While the main focus of the book is the actual steps taken to design an enterprise architecture, other important topics include architecture origin, definition, domains, visualization, and roles. Getting Started with Enterprise Architecture is the ideal handbook for the architect who is asked to implement an Enterprise Architecture in an existing organization. For enterprise architects, project managers and executives. | |

This book primarily aims to provide an in-depth understanding of recent advances in Big Data computing technologies, methodologies, and applications along with introductory details of Big Data computing models such as Apache Hadoop, MapReduce, Hive, Pig, Mahout in-memory storage systems, NoSQL databases, and Big Data streaming services such as Apache Spark, Kafka, and so forth. It also covers developments in Big Data computing applications such as Machine Learning, Deep Learning, graph processing, and many others. Big Data has become a critical issue for businesses to leverage their data assets to drive business decisions considering the exponential growth of data in today’s age. Machine Learning (ML) and Artificial Intelligence (AI) have emerged as powerful tools to extract insights and value from Big Data. Here we will explore a few of the key applications of ML and AI in Big Data. Predictive analytics is one of the most significant applications of ML in Big Data. It involves using existing data to predict future events or behaviors. Predictive analytics may be used to predict future sales, identify customers at risk of churning, or predict the likelihood of a customer purchasing a specific product . In predictive analytics, algorithms such as decision trees, random forests, and neural networks are commonly used. | |
