nach der Bestellung gedruckt Neuware - Printed after ordering - Enhance the performance of your PostgreSQL system with this handy guide while avoiding common pitfalls that can slow it down. Key Features Learn the right techniques to obtain optimal PostgreSQL database performance, ranging from initial design to routine maintenance Fine tune the performance of your queries and avoid the common pitfalls that can slow your system down Contains tips and tricks on scaling successful database installations, and ensuring a highly available PostgreSQL solution Book Description Database administrators and developers spend years learning techniques to configure their PostgreSQL database servers for optimal performance, mostly when they encounter performance issues. Scalability and high availability of the database solution is equally important these days. This book will show you how to configure new database installations and optimize existing database server installations using PostgreSQL 9.6. You will start with the basic concepts of database performance, because all successful database applications are destined to eventually run into issues when scaling up their performance. You will not only learn to optimize your database and queries for optimal performance, but also detect the real performance bottlenecks using PostgreSQL tools and some external tools. Next, you will learn how to benchmark your hardware and tune your operating system. Optimize your queries against the database with the help of right indexes, and monitor every layer, ranging from hardware to queries. Moving on, you will see how connection pooling, caching, partitioning, and replication will help you handle increasing database workloads. Achieving high database performance is not easy, but you can learn it by using the right guide-PostgreSQL 9.6 High Performance. What You Will Learn Learn the best practices to configure your PostgreSQL 9.6 database for optimal performance Write optimal queries and techniques to detect performance issue in queries Fine tune the performance of your queries using benchmarking and indexing techniques Ensure high performance and a highly available database using the scaling and replication techniques Discover how to make informed speed and reliability trade-offs Handle increasing database workloads without any hassle Use monitoring insights to continuously rework the design and configuration for best performance Who This Book Is For This book is for intermediate to advanced database administrators and developers who use or plan to exploit the features of PostgreSQL in the best possible manner. While administrators can benefit from the topics related to the installation, configuration, and optimization of the server, developers will learn how to write optimal queries and address performance issues in their database design. This book will also benefit the PostgreSQL internal architects in being able to monitor the performance using benchmarking tools. Bestandsnummer des Verkäufers 9781788837682

Create unbelievably fast, robust and secure web apps with Django web framework and Python 3.6

Key Features

• Understand URL routing, models, forms, templates, and RESTful services with Django 2.14
• Test, deploy, and scale your web applications efficiently with Amazon Web Services (AWS)

Book Description

Django is a framework designed to balance rapid web development with high performance. It handles high levels of user traffic and interaction, integrates with a variety of databases, and collects and processes data in real time. This book follows a task-based approach to guide you through developing using the Django 2.1 framework.

You'll get started by setting up and configuring Docker containers and a virtual environment for your project. Next, you'll learn how to write reusable pieces of code for your models and manage database changes. You'll then work with forms and views to enter and list data, and even apply practical examples using both templates and JavaScript for the optimum user experience. This Django cookbook will also help you adjust the built-in Django administration to fit your needs and boost security and performance to make your web applications as robust, scalable, and dependable as possible. A dedicated section will later guide you on how to use Django CMS, the popular content management suite. Finally, you'll get up to speed with programming and debugging tricks. The book's systematic approach will also help you easily collect data from different sources and provide it to others in various formats.

By the end of this book, you'll have the skills you need to test and deploy projects to a remote dedicated server and scale your application to meet user demand.

What you will learn

• Learn how to set up the basic configuration necessary to start any Django project
• Build a database structure out of reusable model mixins
• Secure web applications against malicious usage and address common performance bottlenecks
• Integrate and extend the Django CMS
• Construct and manage complex and deep hierarchies
• Import data from local sources and external web services and export it to third parties

Who this book is for

This book is for Python developers working on fast and secure web apps that can scale over time. You'll also find this book useful if you want to upgrade to the latest Django framework. Knowledge of Python 3 along with a basic understanding of the Django framework will be beneficial.
