Hugo Kornelis is an established SQL Server Community expert. He writes, blogs, speaks, tech edits, and researches, focusing mostly on SQL Server perofmrance and execution plans. He was the technical editor for the third edition of Grant Fritchey's "SQL Server Execution Plans". In 2018 he started a project to document all behaviour of SQL Server execution plans at his website, "the SQL Server Execution Plan Reference" (https://sqlserverfast.com/epr)

When not working for the community, Hugo is busy at his day job: freelance database developer./consultant. Hugo has 20 years of experience on SQL Server in various roles. He has a strong database design background but has since specialized into query tuning and execution plans.

Sessions

This session will present you with a fascinating behind-the-scenes deep-dive view of the new column store index feature. How do column store indexes work? How are they built? And how can they yield such enormous performance boosts to some workloads?
In this demo-rich session, Hugo Kornelis shows how the full syntax of MERGE enables more than just synchronizing data. You'll get an overview of all the available options, plus a few surprising pitfalls you may not be aware of.
Indexes are the best instrument for query optimization. But what kind of indexes and on what columns? The key to answering those questions is understanding how indexes are stored and used by SQL Server. And that is exactly what this session is about.
T-SQL user-defined functions may appear to be a good tool for code encapsulation and reuse, but they can have a dramatic impact on performance. In this session, you'll see why they slow down your queries, and how you can avoid this performance hit.
Many people think that normalization stops at Third Normal Form. But there are lots of higher normal forms. And they are not as complex or as irrelevant as often claimed. If you want to design better databases, then come attend this session!
