商品描述

Take a deep dive into perhaps the single most important facet of good performance: indexes, and how to best use them. Recent updates to SQL Server have made it possible to create indexes in situations that in the past would have prevented their use.
Other improvements covered in this book include new dynamic management views, the ability to pause and resume index maintenance, and the ability to more easily recover from failures during index creation and maintenance operations. This new edition also brings new content around the indexing of columnstore and in-memory tables, showing how these new types of tables and the queries that execute against them can also benefit from good indexing practices. 
The book begins with explanations of the types of indexes and how they are stored in databases. Moving deeper into the topic, and further into the book, you will look at the statistics that are accumulated both by indexes and on indexes. You will better understand what indexes are doing in the database and what can be done to mitigate and improve their effect on performance. You will get a look at the Index Advisor now available in Azure SQL Database, and learn how to review and maintain the health of your indexes. The final chapters present a guided tour through a number of scenarios showing approaches you can take to investigate, mitigate, and improve the performance of your database.

What You Will Learn

  • Properly index row store, columnstore, and in-memory tables
  • Review statistics to understand indexing choices made by the optimizer
  • Apply indexing strategies such as covering indexes, included columns, and index intersections
  • Recognize and remove unnecessary indexes
  • Design effective indexes for full-text, spatial, and XML data types
  • Manage the big picture: Encompass all indexes in a database, and all database instances on a server



Who This Book Is For
Database administrators and developers who are ready to lift the performance of their database environment by thoughtfully building indexes to speed up queries that matter the most and make a difference to the business

深入探討良好性能的可能是最重要的方面之一：索引以及如何最佳使用它們。SQL Server 的最新更新使得在過去無法使用索引的情況下，現在可以創建索引。

本書還介紹了其他改進，包括新的動態管理視圖、暫停和恢復索引維護的能力，以及在索引創建和維護操作期間更容易從故障中恢復的能力。這個新版本還提供了關於列存儲和內存表索引的新內容，展示了這些新類型的表和執行對它們的查詢也可以從良好的索引實踐中受益。

本書首先解釋了索引的類型以及它們在數據庫中的存儲方式。更深入地研究這個主題，並進一步深入書中，您將研究索引和在索引上累積的統計信息。您將更好地了解索引在數據庫中的作用以及可以採取哪些措施來減輕和改善它們對性能的影響。您將瞭解 Azure SQL Database 中現有的索引建議器，並學習如何審查和維護索引的健康狀況。最後幾章將通過一些場景的引導，展示您可以採取的方法來調查、減輕和改善數據庫的性能。



您將學到什麼


  • 正確地為行存儲、列存儲和內存表建立索引

  • 審查統計信息以了解優化器所做的索引選擇

  • 應用索引策略，如覆蓋索引、包含列和索引交集

  • 識別並刪除不必要的索引

  • 為全文、空間和 XML 數據類型設計有效的索引

  • 管理全局視圖：涵蓋數據庫中的所有索引，以及服務器上的所有數據庫實例





本書適合對象

準備通過謹慎地構建索引來加快最重要且對業務有影響的查詢速度，從而提高數據庫環境性能的數據庫管理員和開發人員
