PostgreSQL Query Optimization: The Ultimate Guide to Building Efficient Queries

Description: PostgreSQL Query Optimization by Henrietta Dombrovskaya, Boris Novikov, Anna Bailliekova Intermediate-Advanced user level FORMAT Paperback CONDITION Brand New Publisher Description Write optimized queries. This book helps you write queries that perform fast and deliver results on time. You will learn that query optimization is not a dark art practiced by a small, secretive cabal of sorcerers. Any motivated professional can learn to write efficient queries from the get-go and capably optimize existing queries. You will learn to look at the process of writing a query from the database engines point of view, and know how to think like the database optimizer.The book begins with a discussion of what a performant system is and progresses to measuring performance and setting performance goals. It introduces different classes of queries and optimization techniques suitable to each, such as the use of indexes and specific join algorithms. You will learn to read and understand query execution plans along with techniques for influencing those plans for better performance. The book also covers advanced topics such as the use of functions and procedures, dynamic SQL, and generated queries. All of these techniques are then used together to produce performant applications, avoiding the pitfalls of object-relational mappers.This second edition includes new examples using Postgres 15 and the newest version of the PostgresAir database. It includes additional details and clarifications about advanced topics, and covers configuration parameters in greater depth. Finally, it makes use of advancements in NORM, using automatically generated functions. What You Will LearnIdentify optimization goals in OLTP and OLAP systemsRead and understand PostgreSQL execution plansDistinguish between short queries and long queriesChoose the right optimization technique for each query typeIdentify indexes that will improve query performanceOptimize full table scansAvoid the pitfalls of object-relational mapping systemsOptimize the entire application rather than just database queries Who This Book Is ForIT professionals working in PostgreSQL who want to develop performant and scalable applications, anyone whose job title contains the words "database developer" or "database administrator" or who is a backend developer charged with programming database calls, and system architects involved in the overall design of application systems running against a PostgreSQL database Author Biography Henrietta Dombrovskaya is a database researcher and developer with over 40 years of academic and industrial experience. She holds a PhD in Computer Science from the University of Saint Petersburg, Russia. At present, she is a Database Architect at DRW Holdings, Chicago, Illinois. She is an active member of the PostgreSQL community, a frequent speaker at the PostgreSQL conference, and the local organizer of the Chicago PostgreSQL User Group. Her research interests are tightly coupled with practice and are focused on developing efficient interactions between applications and databases.Boris Novikovs experience includes leading post-graduate research groups and advising dozens of PhD students, while partnering and collaborating with industrial clients. His research interests are in the broad area of information management and include design, development, and tuning of databases, applications, and database management systems (DBMSs). He alsohas interests in distributed scalable systems for stream processing and analytics..Anna Bailliekova is Senior Data Engineer at UrbanFootprint, where she works on data platform tools and cloud ops for geospatial applications. Previously, she worked in data engineering at Zendesk, and held a variety of DBA and BI roles at Epic. Her writing can be found in the newsletter Better Streets MKE. She received her undergraduate degree with College Honors in Political Science and Computer Science from Knox College in Galesburg, Illinois. Table of Contents 1. Why Optimize?.- 2.
