Key Features

  • This book shows you the best practices to configure the PostgreSQL database for optimal performance
  • Fine tune the performance of your queries using benchmarking and indexing techniques
  • Ensure high performance and a highly available databases using the scaling and replication techniques

Book Description

This book starts with the basic concepts of database performance, because all successful database applications are destined to eventually run into issues when scaling up their performance. Therefore, you need to understand the basics of database performance.

In this book, 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.

You'll optimize queries against the database, with the right indexes. You'll monitor every layer, from hardware to queries. Some tools are inside PostgreSQL; others are external.

Using monitoring insights, you'll continuously rework the design and configuration. Once reaching the limits of a single server, you'll break things up. Moving on, connection pooling, caching, partitioning, and replication will all help you handle increasing database workloads.

Achieving high database performance is not easy, but you can learn it by using the right guide-this guide.

What you will learn

  • Tune your database within your hardware and operating system limitations
  • Make the right decision on the hardware for your database and application
  • Discover how to make informed speed and reliability trade-offs
  • Understand your operating system's parameters, which can help to improve your database performance
  • Get to know the different techniques and tools to benchmark your databases and hardware
  • Work with the PostgreSQL configuration parameters and use these parameters in real-world scenarios
  • Write optimal queries and techniques to detect performance issue in queries

主要特點


  • 本書展示了配置 PostgreSQL 數據庫以實現最佳性能的最佳實踐

  • 使用基準測試和索引技術微調查詢的性能

  • 使用擴展和複製技術確保高性能和高可用性的數據庫

書籍描述

本書從數據庫性能的基本概念開始,因為所有成功的數據庫應用程序最終都會在擴展性能時遇到問題。因此,您需要了解數據庫性能的基礎知識。

在本書中,您不僅將學習如何優化數據庫和查詢以實現最佳性能,還將使用 PostgreSQL 工具和一些外部工具檢測真正的性能瓶頸。接下來,您將學習如何對硬件進行基準測試並調整操作系統。

您將通過適當的索引優化數據庫的查詢。您將監控從硬件到查詢的每一層。一些工具內置於 PostgreSQL 中,其他工具則是外部工具。

使用監控洞察力,您將不斷重新設計和配置。一旦單個服務器達到極限,您將進行分割。連接池、緩存、分區和複製將幫助您處理不斷增加的數據庫工作負載。

實現高性能數據庫並不容易,但您可以通過使用正確的指南來學習。

您將學到什麼


  • 在硬件和操作系統限制內調整您的數據庫

  • 為您的數據庫和應用程序做出正確的硬件選擇

  • 了解如何做出明智的速度和可靠性折衷

  • 了解操作系統的參數,有助於提高數據庫性能

  • 了解不同的技術和工具來對數據庫和硬件進行基準測試

  • 使用 PostgreSQL 配置參數,在實際場景中使用這些參數

  • 編寫最佳查詢和檢測查詢性能問題的技巧
