Join Me And @Kendra_Little At @PASSDataSummit For 2 Days Of SQL Server Performance Tuning Precons!

Last Year


Kendra and I both taught solo precons, and got to talking about how much easier it is to manage large crowds when you have a little helper with you, and decided to submit two precons this year that we’d co-present.

Amazingly, they both got accepted. Cheers and applause. So this year, we’ll be double-teaming Monday and Tuesday with a couple pretty cool precons.

You can register for PASS Summit here, taking place live and in-person November 4-8 in Seattle.

Here are the details!

Day One: A Practical Guide to Performance Tuning Internals


Whether you’re aiming to be the next great query tuning wizard or you simply need to tackle tough business problems at work, you need to understand what makes a workload run fast– and especially what makes it run slowly.

Erik Darling and Kendra Little will show you the practical way forward, and will introduce you to the internal subsystems of SQL Server with a practical guide to their capabilities, weaknesses, and most importantly what you need to know to troubleshoot them as a developer or DBA.

They’ll teach you how to use your understanding of the database engine, the storage engine, and the query optimizer to analyze problems and identify what is a nothingburger best practice and what changes will pay off with measurable improvements.

With a blend of bad jokes, expertise, and proven strategies, Erik and Kendra will set you up with practical skills and a clear understanding of how to apply these lessons to see immediate improvements in your own environments.

Day Two: Query Quest: Conquer SQL Server Performance Monsters


Picture this: a day crammed with fun, fascinating demonstrations for SQL Server and Azure SQL.

This isn’t your typical training day; this session follows the mantra of “learning by doing,” with a good dose of the unexpected. Think of this as a SQL Server video game, where Erik Darling and Kendra Little guide you through levels of weird query monsters and performance tuning obstacles.

By the time we reach the final boss, you’ll have developed an appetite for exploring the unknown and leveled up your confidence to tackle even the most daunting of database dilemmas.

It’s SQL Server, but not as you know it—more fun, more fascinating, and more scalable than you thought possible.

We’re both really excited to deliver these, and have BIG PLANS to have these sessions build on each other so folks who attend both days have a real sense of continuity.

Of course, you’re welcome to pick and choose, but who’d wanna miss out on either of these with accolades like this?

Spring Training


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

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.

Event Details:

Happy Labor Day, From Darling Data

Holiday In Suburbia


You may be reading this and thinking “what does a consultant know about labor?”

Well, I wasn’t always this idle in my profession. I’ve had a variety of jobs in my life that have hardened the hands and stiffened the back. Now I mostly harden my liver with stiff drinks.

Mostly I’m celebrating that I have soft hands again.

Remember to moisturize, friends.

If you’ve got the day off, make it a good one. See you tomorrow.

Thanks for reading!
