Identify, analyze, and improve poorly performing queries that damage user experience and lead to lost revenue for your business. This book will help you make query tuning an integral part of your daily routine through a multi-step process that includes monitoring of execution times, identifying candidate queries for optimization, analyzing their current performance, and improving them to deliver results faster and with less overhead. Author Jesper Krogh systematically discusses each of these steps along with the data sources and the tools used to perform them.
MySQL 8 Query Performance Tuning aims to help you improve query performance using a wide range of strategies. You will know how to analyze queries using both the traditional EXPLAIN command as well as the new EXPLAIN ANALYZE tool. You also will see how to use the Visual Explain feature to provide a visually-oriented view of an execution plan. Coverage of indexes includes indexing strategies and index statistics, and you will learn how histograms can be used to provide input on skewed data distributions that the optimizer can use to improve query performance. You will learn about locks, and how to investigate locking issues. And you will come away with an understanding of how the MySQL optimizer works, including the new hash join algorithm, and how to change the optimizer's behavior when needed to deliver faster execution times. You will gain the tools and skills needed to delight application users and to squeeze the most value from corporate computing resources.

What You Will Learn

  • Monitor query performance to identify poor performers
  • Choose queries to optimize that will provide the greatest gain
  • Analyze queries using tools such as EXPLAIN ANALYZE and Visual Explain
  • Improve slow queries through a wide range of strategies
  • Properly deploy indexes and histograms to aid in creating fast execution plans
  • Understand and analyze locks to resolve contention and increase throughput

Who This Book Is For
Database administrators and SQL developers who are familiar with MySQL and need to participate in query turning. While some experience with MySQL is required, no prior knowledge of query performance tuning is needed.



這本書名為《MySQL 8 Query Performance Tuning》,旨在幫助您使用各種策略來改善查詢性能。您將學習如何使用傳統的EXPLAIN命令和新的EXPLAIN ANALYZE工具來分析查詢。您還將了解如何使用視覺化解釋功能提供執行計劃的視覺化視圖。索引的涵蓋範圍包括索引策略和索引統計,您將學習如何使用直方圖來提供有關傾斜數據分佈的輸入,以便優化器可以改善查詢性能。您將學習鎖定以及如何調查鎖定問題。您將了解MySQL優化器的工作原理,包括新的哈希連接算法,以及在需要時如何更改優化器的行為以提供更快的執行時間。您將獲得所需的工具和技能,以滿足應用程序用戶的需求,並從企業計算資源中獲得最大價值。
