Description

Today's database workloads are all about bigger, better, and more: bigger data, better analytics, and more insights. While these improvements can be great for your business users, on the technology side they often translate into large, lumbering queries that monopolize the server and test the patience of even the calmest of analysts. This full-day seminar is specifically designed to help you tune these extra tough queries. The day begins by establishing a solid foundation for reading and understanding how query plans work, and what is and is not important to pay attention to when reading a plan. Next you will learn about plan shaping: types of query rewrites that work, which rewrites are bound to fail, and the various query hints you might want to leverage in especially difficult situations. Real-world application of these techniques will be covered with a discussion around how to understand what kind of plan is ideal given the particulars of a situation, and the introduction of an approach to help you analyze and fix even the biggest query plans. The day concludes with a look at various indexing strategies and patterns--both common and alternative, including a look at the applicability of columnstores in SQL Server 2016 and beyond. You will leave the class armed with an array of tools and ideas to help you tame even the biggest queries in your environment.
