Spring Training

This September, I’ll be presenting my full day training session The Foundations Of SQL Server Performance Tuning for Data Saturday Dallas.

All attendees will get free access for life to my SQL Server performance tuning training. That’s about 25 hours of streaming on-demand content.

Get your tickets here for my precon, taking place Friday, September 6th 2024, at Microsoft Corporation 7000 State Highway 161 Irving, TX 75039

Here’s what I’ll be presenting:

The Foundations Of SQL Server Performance Tuning

Session Abstract:

Whether you want to be the next great query tuning wizard, or you just need to learn how to start solving tough business problems at work, you need a solid understanding of not only what makes things fast, but also what makes them slow.

I work with consulting clients worldwide fixing complex SQL Server performance problems. I want to teach you how to do the same thing using the same troubleshooting tools and techniques I do.

I’m going to crack open my bag of tricks and show you exactly how I find which queries to tune, indexes to add, and changes to make. In this day long session, you’re going to learn about hardware, query rewrites that work, effective index design patterns, and more.

Before you get to the cutting edge, you need to have a good foundation. I’m going to teach you how to find and fix performance problems with confidence.

Everything You Know About Isolation Levels Is Wrong

The PASS Data Summit session lineup has been announced! And, you know, since me and Kendra are double-teaming two days of precons Nov 4-8 in Seattle, I’ve got a regular session too!

Everything You Know About Isolation Levels Is Wrong

You’ve been told that NOLOCK hints are bad, so you look at all the queries your developers write and hang your head in shame.

A NOLOCK hint here, a NOLOCK there, a NOLOCK hint seemingly everywhere. Like termites, eating at the foundation of your well-being.

But in the real world, how are you supposed to remove those all those yucky hints without blocking and deadlocking causing huge problems?

I’m Erik Darling, a world class NOLOCK hint removal expert, and in this demo-heavy session, I’ll change your mind about every isolation level. You’re going to learn why:

• Read Committed is nearly as weak as Read Uncommitted
• Optimistic isolation levels aren’t incorrect-result factories
• Repeatable Read isn’t what it sounds like
• Serializable isn’t the enemy of concurrency
• You don’t need to worry about tempdb’s version store
• No isolation level is perfect for every workload

At the end, you’ll have the confidence and knowledge to start turning on optimistic isolation levels and stop hanging NOLOCK hints all over your queries like Christmas tree ornaments.

Session Prerequisites: Basic understanding of locking and blocking problems, some familiarity with isolation levels.
