Abstract: Is it possible to teach somebody to optimize? Or is optimization a sort of magic, available only for the limited circle of wizards? We believe that it is entirely possible to become an optimization wizard, and we are going to prove it in the course of this training. We will provide the participants with the opportunity to look at the process of query writing “as a database engine”, and will teach them “how to think, as a database engine”.

The topics which will be covered include:

  • What is a performant system, and how we measure performance
  • Performance in OLTP and OLAP systems
  • What are short queries and long queries and how to distinguish one from another
  • Join algorithms and how to control them
  • Indexes, good and bad, how to use and how not to use them
  • The art of full scan
  • The usage of functions: how they can improve performance, and how they can degrade it
  • Application/database interaction: how you can improve application performance
  • The power of generated queries

The training will end with the presentation of the Ultimate Optimization Algorithm, which guides a database developer through the process of optimizing virtually any query
