[Video] Office Hours: Black Friday Edition


My Black Friday sale is in its last days, so most of my time at the moment is spent keeping an eye on the site and answering customer questions. I’m happy to say it’s our best year so far, too! Y’all really like the new access-for-life options.

I took a break from the online frenzy to check in on the questions you posted at and answer the highest-voted ones:

Here’s what we covered:

  • 00:00 Start
  • 00:30 Marian: The database that my company developed for over 20 years has a lot design problems, with very obvious normalization and performance issues. The business approach is keep fixing whatever issues are and will appear. Would you rather recommend developing a new one, or keep fixing?
  • 02:53 George : Hi Brent, I’m a sql dev /learning performance dba (enthusiastic amateur). We have an external consultant who has stated that sql server is self tuning and reevaluates after 3 runs. I cannot find anything about this online, do you have any idea of what they might mean?
  • 04:05 ChiHarley: Microsoft is pushing my client to activate the SQL IaaS Extension on their Azure VMs. Do you like to enable the extension, or do you have an opinion on it?
  • 05:42 Brentosaur: How about creating “Funtamentals of Locks and Blocking” classes? I would love to watch them
  • 06:31 Carlo: Hi Brent, any updates regarding the problem of ‘AlwaysOn’ cluster errors due to heart-beat timeout based on Veeam VM snapshots? Thanks!
  • 07:36 Jessica: Hey brent, have you recently done a talk on / know a good recent talk on youtube for setting up Log Shipping for DR? Its been a while since the last time I had to deal with it (2008R2 in 2012 or so) and wanted to make sure there aren’t any new gotchas
  • 08:20 Cassian: How do you know if auto growth events are benign or problematic?
  • 09:33 Double espressos for breakfast: Hi Brent – love all that you have done for the SQL community. You’re clearly a bright guy and could do anything you put your mind to. Why did you choose database administration of all things?

Contest: Guess the Next SQL Server Release Date

SQL Server 2023

When will Microsoft officially release SQL Server 2023 (or 2024, or whatever it’ll be) for download? The dust is just barely starting to settle on the 2022 box, so it’s time to guess the next one.

  • Leave one – and only one – comment here in YYYY/MM/DD format with your release date guess. If you leave multiple comments, only the first/earliest one is going to count.
  • “The release date” is the date that Microsoft announces that the final RTM bits will be downloadable to the public from (Not the date they make the announcement, and we’re only talking the release-to-manufacturing public version, not a preview, CTP, RC, CU, or SP.)
  • Closest to win, without going over, wins lifetime access to my Fundamentals & Mastering recorded classes.
  • In the event of a tie (multiple people guessing the same date), the earlier comment wins.
  • Only comments more than 48 hours before than Microsoft’s public release announcement will count. If Microsoft makes their announcement, and you run over here trying to leave a fast comment with the release date, not gonna take it.
  • If Microsoft announces two release dates – like one for Windows, and one for Linux – then we’ll pick a separate winner for each. (But you only get to leave one date in the comments.)

Place your bets!

Are You Underpaid? Let’s Find Out: The 7th Annual Data Professional Salary Survey is Open.


Whew. This is a crazy time, isn’t it? The aftermath of the pandemic is kicking in, and there are layoffs happening in Silicon Valley companies, but… the data profession is on fire. I don’t know anyone who’s been out of work for too long because companies are so desperate to get data help.

So it’s time for our annual salary survey to find out what data professionals make. You fill out the data, we open source the whole thing, and you can analyze the data to spot trends and do a better job of negotiating your own salary:

We pay Richie in query bucks

Take the Data Professional Salary Survey now.

The anonymous survey closes Sunday, Jan 1. The results are completely open source, and shared with the community for your analysis. (You can analyze ’em now mid-flight, but I’d wait until the final results come in. I’ll combine them into a single spreadsheet with the past results, and publish those on January 3rd.)

Thanks for your help in giving everybody in the community a better chance to talk honestly with their managers about salary.

Update Jan 2: this year’s salary is closed, and the results are here.

Looking Back at the 2022 #PASSDataCommunitySummit in Seattle


I’m back home in Vegas, back down to Inbox Zero, and I’ve had some time to think about last week’s conference in Seattle. I liveblogged the keynotes, but I wanted to talk about the conference overall.

This was Redgate’s first time running an in-person Summit after the professional organization folded in December 2020. Redgate bought the Summit’s assets, ran a virtual event last year, and then this year was a hybrid event. You could either attend in person, or online.

Overall, the in-person event went well. The rooms were well-sized, the AV worked fine, lunches were served quickly. Given that it was the Summit’s first return to “normality” in a while, things could have been much worse. We got really lucky with the weather: sun every day, and not a drop of rain.

In-person attendance was down, but still big. I heard total in-person attendance was around 1,500 folks, which probably includes the vendor & support staff, down from a pre-COVID height of around 4,000. Pre-conference workshop attendance was way down – peaked around 80 in-person, down from 350+. In any given pre-pandemic year, this still probably would have been the biggest Microsoft data platform event in the US.

The virtual side had a lot of glitches. Online attendees couldn’t join all sessions, or missed the first part of sessions, and some recordings didn’t work. Running a live in-person event is hard enough, and I salute Redgate for trying to make the hybrid thing work, but it seemed like there was still a lot of work to do on that. I wonder if next year will be hybrid again, or in-person only. If you’re considering attending the hybrid version, you should set your expectations appropriately: stuff may not work.

I was happy not attending sessions. Leading up to the event, I shared with y’all that I was going to skip sessions altogether and do the hallway track instead, meeting my friends and having little family reunions all over the place. I didn’t take any photos, but the event photographers were all over the place, and I’m guessing there will be a public photo album somewhere. I heard there were a lot of good Microsoft-delivered sessions about SQL Server 2022 and Azure Managed Instances, so I’ll go back and peruse the recordings of those later.

There weren’t many health precautions. Very, very few folks wore masks, there was no social distancing, no mandatory testing, and lots of people (myself included) were shaking hands and hugging. I’m telling you this, dear reader, because I know that a lot of y’all are still at home, and haven’t gone to public events yet. If and when you return to in-person events again, I just want you to have a rough idea of what to expect.

I will likely return in 2023. I had a good time, I loved reuniting with my friends, and Redgate did a good job of stewarding the event. I can’t think of any reasons why I wouldn’t go back. It went well!

#PASSdataCommunitySummit Keynote Day 3 Live Blog

SQL Server
1 Comment

Today at the PASS Data Community Summit in Seattle, Kimberly Tripp is doing the first-ever in-person community keynote. Here’s the abstract:

Over the 30+ years I’ve been working with SQL Server, I’ve seen an incredible amount of innovation and change. How do we keep up with so many changes and how do we know how and when to implement them when there are so many options? I’ve always said that my favorite thing about SQL Server is that you can solve virtually any problem – by knowing the RIGHT way to solve it. Each feature has options and tweaks that make it better suited for some scenarios and inappropriate for others. And that’s led us to the “it depends” response. However, “it depends” is NOT the answer, it’s just the beginning. The beginning of a process where you understand your goals, design your strategy / prototype, and apply the appropriate technology after you’ve defined your specifications. But how do you keep up with the innovation? How do you keep your team happy? Learning, Sharing, and Growing – these are the mainstays of a cohesive and productive team not to mention, the best way to leverage such a powerful platform.

Kimberly TrippI’ll be live-blogging the keynote, sharing my thoughts about what happens. You can refresh the post to follow along – the most current notes will be at the bottom, so if you’re reading later, you can read through the recap as it happened.

7:55AM: Folks are trickling into the keynote room to the tunes of smoooooth jaaaaazzz again. This music is a perfect fit for the chill Friday. Attendance will be lower today as folks start to travel home.

8:02AM: Steve Jones took the stage to talk about how Redgate wanted the 3rd day of the Summit to have a community keynote.

8:06AM: Steve talked about how SQL Saturday grew from 1 event in 2007, to over 100 events a year in 2019. PASS acquired that brand several years ago, and then when Redgate acquired PASS, Redgate gave the SQLSaturday brand away to a non-profit 501.3c. Steve hopes to see more events in 2023.

8:07AM: Thanks to AWS for sponsoring the Day 3 Community Keynote.

8:08AM: KillaDBA (Homer McEwen) took the stage to sing his song Hug a DBA. I believe this is the first song in history to correctly use the word ‘tuple.’

8:11AM: Another one! His new song about SQL Server 2022. Dang, he’s fast with the words.

8:15AM: Steve Jones brought Kimberly Tripp onstage: “I started working with SQL Server when I was 2, and it’s been a fun 33 years.” I laughed out loud. Nicely done.

8:20AM: Kim brought Paul Randal onstage to help.

8:21AM: Kim reviewed the history of SQL Server. In May 1989, SQL Server 1.0 for OS/2 was released. It was a single process that ran on a single thread.

8:22AM: Kim & Paul showed boxes of SQL Server 4.21 for Windows NT. It looks like Paul’s about to run the world’s worst used software auction onstage, hahaha.

8:24AM: Kim did a show of hands of people who started with SQL Server 6.5, and a lot of hands went up. (Me too.) She talked about how it’s amazing that so many of us have stuck with the same product over the years, and she said it might be due to the quality of the community.

8:30AM: Kim said circa 2019, Twitter was handling 500 million tweets a day, and email was handling 294 billion emails a day. (Most of which on both platforms was spam, heh.) In 2021, Google was handling about 8 billion searches per day.

8:34AM: In Kim’s survey of the community, 48% said they always use a search engine, and another 46% frequently use search engines. We kinda take that for granted now, but when us old people got started in databases, that simply wasn’t an option.

8:43AM: Kim covered a lot of changes in hardware, storage, and the data we’ve handled over the last 30 years. Her message is that big data isn’t a fad: it’s the same as it’s always been. It just keeps growing.

8:48AM: The SQL Server storage engine was rewritten in 7.0, and most of the basic design ideas (like 8KB pages) have lasted 20 years. Kim pointed out that even though there are new storage structures (In-Memory OLTP, columnstore), most of the time, the 20 year old stuff is still the most appropriate.

8:53AM: Kim said that when the folks in the audience chose a career, they chose wisely. Data is growing, the field is growing, businesses are realizing its worth. Kim said that on Career Builder right now, 13,073 jobs show up for Database Administrator.

8:56AM: “There’s enough work out there for all of us.” Kim encouraged everyone to learn, share, and grow in the community.

9:03AM: Kim gave everyone homework. Grab the title slide from every session they attended, create 1-2 slides with highlights in their own words from each session, and present that to their manager and their team. Great idea, because it proves the ROI of sending people to a conference, and helps you get budgetary approval for next year.

And hopefully I’ll see YOU here next year, dear reader! Off to the Community Zone to hang out with folks.

#PASSdataCommunitySummit Keynote Day 2 Live Blog


I’m in Seattle for the PASS Data Community Summit, and the day 2 keynote is about to start. This year, now that Redgate owns the Summit event, they’re doing the day 2 keynote. Gotta pay the bills, I suppose!

Redgate’s CEO, Jakub Lamik, is leading a team of speakers for the keynote, and here’s the abstract:

These are challenging times for every business everywhere. So how can you ensure you get the most from your investment in IT, to meet your needs now, while also preparing you for an uncertain future? Join Jakub Lamik, Steve Jones and Kathi Kellenberger in this keynote which looks at how the world is changing for data professionals, and the areas to focus on which will bring the best return on your investment in the long term.

Given that it’s essentially a vendor keynote, it would be safe to assume that it’s advertising for Redgate’s products. Over the last couple of years, they’ve focused more and more on DevOps tooling.

I’ll be live-blogging the keynote, sharing my thoughts about what happens. You can refresh the post to follow along – the most current notes will be at the bottom, so if you’re reading later, you can read through the recap as it happened.

7:57AM: as folks enter, the soundtrack is very smoooooth jaaaaaaaazzzzz. Easy listening. I think they know how hung over I am. In related news: I had a great time last night at Matt’s in the Market, and then Rumba.

8:04AM: people slowly filing in. The picture looks empty, but it’s just because it takes quite a while to upload photos over the wifi, so I started early.

8:06AM: Cecilia Judmann, events manager for Redgate, took the stage for her first Summit too. I wanna say I saw that 40% of the attendees are here for their first Summit, period. That’s amazing! So cool to get fresh blood in.

8:10AM: Steve Jones took the stage. Summit and Redgate both started in 1999. Steve was there at the very first Summit! That’s wild. He talked about how attendees used to dash from session to session, taking notes on paper, because back then laptops weren’t really feasible and the battery life was terrible.

8:14AM: Steve really misses the Casino Night party they used to put on. I miss that too! I only got to attend one of ’em – my schedule was a zoo – but I would love to attend that again.

8:16AM: In 1999, the conference was 75 sessions with 1,200 attendees. 2019, it had grown to 200 sessions, 21 pre-conference workshops, and 4,000 attendees.

8:18AM: SQLPrompt was Redgate’s first DevOps attempt. They started pair programming, trying to release fixes within a week. They were able to push 100+ releases in a year. That might sound like a lot of patches, but it’s totally fair – people do TERRIBLE things with their T-SQL and tables, and I’m sure SQLPrompt had to deal with an insane number of edge cases.

8:19AM: Steve Jones and a couple of other folks founded SQLServerCentral about 20 years ago, and Redgate acquired that as well (like they acquired SQLPrompt) in order to make the community better. Hey, I see a theme here! Redgate’s been making smart acquisitions for a long time. I like the theme of this.

8:21AM: When the business organization behind the PASS Summit imploded due to the pandemic, Redgate acquired the assets because the Summit was too good and too big to fail. Plus, Redgate spun off SQLSaturday, the community events, to a separate non-profit.

8:22AM: Redgate CEO Jakub Lamik took the stage to talk about why Redgate believed that the Summit was important to preserve. Data has been important for 20 years, and it’ll continue to be important for the next 20 years, too.

8:26AM: Lamik discussed how open source is increasingly popular across all segments, including the enterprise. Small teams can get traction quickly with open source tools and generate value. This may not sound like a revolutionary point, but remember where it’s being discussed: from the keynote stage at what used to be a very Microsoft-specific data conference. It took a long, long time before things like AWS and GCP were discussed here, let alone alternate databases. Redgate hosting this event means they can be more frank about the reality of other databases – after all, they sell tooling for other databases.

8:28AM: The top databases used by developers in the Stack Overflow survey were PostgreSQL, MySQL, SQLite, and then #4, Microsoft SQL Server. Again, this is the kind of discussion we gotta have. It’s not that you can’t make a career out of Microsoft SQL Server alone – you can – but it helps to remember your context, and data lives everywhere.

8:32AM: Data work involves a lot of steps – coding, testing, deployment, troubleshooting, etc. If you multiply that across lots of different databases, it means everything’s a hot mess of variations, probably all manual footwork. Redgate wants to treat all databases the same way to reduce errors, improve time to deliver solutions, and let less people manage more stuff.

8:33AM: David Bick, head of product management, took the stage to discuss how Flyway, the open source migration tool Redgate acquired in 2015, supports 25+ databases including PostgreSQL, SQL Server, Snowflake, MySQL, Oracle, etc. It’s still open source, but there’s now a Flyway Enterprise layer atop it as well.

8:41AM: Video demo of Flyway watching a database server, noticing a table change, and checking that change into source control. The pull request kicked off a series of automated tests to make sure things compiled, didn’t throw errors, etc. Then in Github, the DBA gets a list of changes and deployment scripts. (I love the idea of this, but I’m probably biased because I actually love Github, and I know it’s foreign to a lot of DBAs.)

8:42AM: Demoing Redgate Clone to restore the 400GB Stack Overflow database for deployment purposes. If you actually have to do this restore, it’s slow as hell (I know, because I have to do this regularly) – and it’s only going to be worse if you’re doing it in a low-powered container being used for automated testing. You don’t wanna wait 20-30-40 minutes for a restore to run in order to test a 1-line T-SQL script. Clone looks like a no-brainer for automated testing, and I can see how it adds value to Flyway.

8:44AM: Flyway Enterprise supports SQL Server and Oracle today. PostgreSQL, MySQL, and Redgate Clone will hit in Q1 2023.

8:45AM: Jakub came back onstage to talk about how DBAs are now supposed to be datacenter-agnostic. We’re expected to support on-premises and cloud databases, and data that flows back & forth.

8:47AM: Arneh Eskandari, Solutions Engineering Manager for Redgate, came onstage to say, “On-prem databases aren’t going away anytime soon.” Again, this is good to hear from the keynote stage. Microsoft speakers often make it sound like Azure is the only thing anyone is deploying today, and that simply isn’t true – and it sends the wrong message to attendees. This is the honest message, and this is good.

8:55AM: wifi bombed out there for a few minutes. For tomorrow’s keynote with Kimberly Tripp, I’ll do the liveblogging differently – I’ll just tweet it, and then edit the tweets together into a blog post after the event. (Plus, I don’t wanna carry my laptop around the conference tomorrow – my last session is today, a lightning talk about fragmentation in the afternoon.)

8:56AM: Jakub back onstage. “Everything is changing. The role of database professionals is evolving. The need for data professionals is bigger than ever.”

8:58AM: Kathi Kellenberger, Redgate Customer Success Engineer and the Queen of SQL Karaoke, took the stage. Of the 377 speakers at this event, more speakers than ever are first-timers. Kathi and Redgate are committed to help your career – by getting you up onstage speaking, helping keep Summit and SQLSaturday alive, SQLServerCentral and Simple Talk help you solve problems.

9:06AM: Kathi explained how writing articles for SQLServerCentral and SimpleTalk was the entry point in her career back in 2005, helping her sharpen her skills by helping others, and it opened lots of doors for her. She eventually went to work for Redgate as SimpleTalk’s editor, and now that role has been passed on to Louis Davidson. (He’s back home in Tennessee working on the hybrid side of the Summit.)

9:09AM: Kathi’s now on the Customer Success team, making sure customers can successfully leverage the software. With something as complex and ever-changing as DevOps, you actually need that layer of consulting. A lot of complex apps end up becoming shelfware, sitting on the shelf without anyone using ’em, because the tool was just too hard, not intuitive enough, or not documented well. Customer Success teams help mitigate that problem, which means companies are more likely to get hooked on that complex software, and then stick with it, paying maintenance over the years. Everybody wins.

9:10AM: The Redgate 100 is their list of top database community influencers. (Hey, I’m in there!)

It’s a wrap! Off to the conference.

SQL Server 2022 Paid Editions Require a Licensing Key.

SQL Server 2022

For the final release of SQL Server 2022, Microsoft popped a surprise that wasn’t in the release candidates:

Your choices are:

  • Install a free edition: Evaluation (which times out after 180 days), Developer (which isn’t allowed to be used for production purposes), or Express (which is limited to small databases & hardware resources)
  • Use pay-as-you-go-billing, which requires you to connect the SQL Server to your Azure account
  • Put in a product key if you want to use Standard, Enterprise, or Web Edition


Microsoft deserves to get paid for their work, just like you, dear reader.

This is a significant change from past behaviors, taking us back to the days of SQL Server 2000 (or thereabouts?) when we had to put in license keys. Back then, the setup process simply validated the key, but didn’t phone home to Microsoft to see if the key was being used repeatedly across lots of SQL Servers.

Logistically, this is a little tricky to enforce. You can buy SQL Server licenses in 2-core packs, each of which would presumably have its own key. The setup doesn’t appear to allow you to put in multiple keys, so it would seem that you could buy a 2 CPU pack of Enterprise, then install it on a 128-core server and put that key in.

Baby steps.

Join #TeamHugo and Help Fight Leukemia.


If you’ve been reading this blog for a while or subscribed to my email newsletters, you’ve learned something from Hugo Kornelis.

Hugo is the wildly productive and selfless guy behind the Execution Plan Reference,, tons of SQLBits sessionsvideos on YouTube, and he’s @Hugo_Kornelis. He’s unbelievably upbeat and positive. He loves what he does, and he loves sharing it with others. Every time I’ve had the blessing to interact with Hugo, I’ve come away grinning.

Today is the opening day of the PASS Summit in Seattle, and on any other opening day, Hugo would be right here with us, grinning and greeting everybody. We’d be talking excitedly about whatever was happening onstage.

This year is different: Hugo is fighting Acute Myeloid Leukemia (AML.)

Right now, as you read this, a bunch of us are wearing #TeamHugo shirts in Seattle to raise awareness of Hugo’s fight. Here’s what you can do to help:

I’m disabling comments on this post because I want all of your positive energy heading in Hugo’s direction. He’s usually the one who brings the rest of us up – and now it’s time for us to lift him up in return.

#PASSdataCommunitySummit Keynote Day 1 Live Blog: SQL Server 2022 is Out Now.


I’m in Seattle for the biggest annual gathering of Microsoft data platform professionals, the PASS Data Community Summit. This is the first in-person Summit since the pandemic, and the first since Redgate took over ownership from the old PASS organization. I’m really excited – this is like a family reunion for me.

Microsoft’s Rohan Kumar is kicking things off this morning as we speak with the Day 1 keynote. Rohan is the corporate vice president of Microsoft Azure Data, and he’ll likely be introducing lots of other Microsoft folks to cover things during the keynote.

Rohan KumarHistorically, the Summit’s day 1 keynote has covered:

  • Reminders of recent Microsoft data features
  • Release dates for upcoming products
  • Customer success stories from companies who’ve been using the products prior to their official release

There’s less than 60 days left in the year 2022, and we still don’t have a release date, pricing, or Standard vs Enterprise feature lists for SQL Server 2022. It’s reasonable to expect these things to finally be revealed – or if not, perhaps a rename to SQL Server 2023.

You shouldn’t expect outright surprises for SQL Server 2022 – as in, “Hey, here’s an all-new feature for SQL Server 2022 that we’re announcing for the first time!” After all, we’ve already got Release Candidate 1. Instead, the Day 1 keynote is usually used to remind folks who don’t stay quite as in-tune with the news as you do, dear reader – not everybody’s savvy enough to read my blog.

I’ll be live-blogging the keynote, sharing my thoughts about what happens. You can refresh the post to follow along – the most current notes will be at the bottom, so if you’re reading later, you can read through the recap as it happened.

7:30AM: Registration is open! So cool to see it back in the same spot, like coming home.

7:40AM: Azure Data Studio v1.4 brings Apple Silicon support. It’s now compiled natively for ARM, so it’s faster. The keynote hasn’t started yet, but I just noticed that got published today, and I wouldn’t be surprised if it was mentioned onstage. I’ve used Azure Data Studio on my Mac for quite a while, but the speed improvements will be very welcome because startup time has been pretty slow. (I know, I know, I should just leave it running.)

8:02AM: The doors opened, and attendees are pouring in.

8:10 Kate Duggan, Chief Marketing Officer for Redgate, took the stage to welcome everyone and talk about how big the event is. (The WiFi is overloaded, so I’m probably not going to be able to upload photos of things as they unfold.)

8:15: Amusing behind-the-scenes videos of people traveling to their first in-person event in years. (Seriously, this is more true than y’all might know – several speakers I’ve talked to have said, “I totally forgot things I used to routinely bring to events, and I forgot how I used to pack.”

8:20: Rohan Kumar, Microsoft’s Corporate Vice President of Azure Data, takes the stage.

Rohan: “While all of you are familiar with the star player, SQL Server…” Not a bad way to segue into saying, “I’m gonna talk about Azure stuff because you already know SQL Server.” That’s fair. Keynotes are useful for vendor education, and as rapidly as things keep changing, people need Azure education.

8:26AM: SQL Server 2022 is generally available now. That’s not coming from the keynote – that’s from a blog that probably went live a few minutes too early. Here’s the full release post.

8:30AM: The winner of my Guess the Release Date Contest is interesting. Nobody actually guessed 2022/11/16 in the proper date format, at least. Scott Holiday was the only person to guess 2022/11/15 (closest without going over), so he wins.

8:36AM: Failover to Managed Instances isn’t ready yet. In the footnotes of the release post, Microsoft notes:

The bidirectional disaster recovery capability of the Link feature for Azure SQL Managed Instance is available in limited public preview.?General availability will occur at a future date.

That’s a bummer because it’s one of the most widely anticipated features, but at the same time, you don’t wanna use something that complex until it’s ready. It reminds me of how database mirroring wasn’t supported until a service pack came out.

8:39AM: Rohan acknowledges that some companies aren’t moving to the cloud yet, or can’t due to country regulations.

8:40AM: Announcing a new pay-as-you-go SQL Server licensing model. You can already do this in the cloud (AWS/Azure/GCP), but now Microsoft will rent you the licenses on premises, too.

8:41AM: Bob Ward and Anna Hoffman took the stage to talk about Azure-connected SQL Servers. God bless ’em for trying to make a security demo amusing.

8:46AM: Anna demoed the pay-as-you-go license choice built into the SQL Server 2022 installer. Nobody clapped, but I seriously should have clapped because that’s bad ass. Assuming the Azure authentication is pretty quick & easy – and I bet it would be – then this makes managing your licenses way easier. Let Microsoft do the accounting.

8:48AM: Anna demoed the failover and failback feature of SQL Server 2022 to Azure Managed Instances. (This is the part that is only in preview now, not generally available yet.)

8:51AM: Video about how Mediterranean Shipping Company (yay, Javier Villegas) is leveraging the Microsoft data platform.

8:53AM: Bob Ward and Conor Cunningham taking the stage in cowboy hats, to the tune of country guitar music. Since 2022 is code named Dallas, they wanted Rohan Kumar to wear a cowboy hat.

8:55AM: Bob Ward demoed Degree of Parallelism Feedback. He used Perfmon (there wouldn’t be a keynote without Perfmon) to measure parallelism, demoing 2022’s new Degree of Parallelism Feedback. Query Store shows how query performance improved over time, cutting the degrees of parallelism, and the query got faster with less cores. Conor talked about how 2016’s Query Store built the foundation for this, and how he’s excited to see tools continue to leverage it. He casually mentioned that row mode queries don’t scale well beyond 8-16 cores, but batch mode queries do.

9:00AM: Conor Cunningham showing a preview build that does lock escalation differently. This demo is just about impossible to follow. It would have been better in plain English to just say, “We’re trying to solve lock escalation problems,” hahaha.

9:01AM: Lindsey Allen jumping into the stage to show Azure Data Studio with Github Copilot. She started writing a comment first to explain what she wanted, and then typed SELECT, and Copilot guessed the function she wanted based on her comment. It’s basically English Query. This will be amusing to see SQL Server discover the intellectual property risks of Copilot that other language developers are already arguing (and suing) about.

9:05AM: Rohan back onstage to talk about Managed Instance Link feature (HA/DR failover to/from cloud), and backup portability (restore MI backups down on-premises to SQL Server 2022.) The slide says “General Availability”, but that’s a little tricky since the 2022 RTM release post says MI Link isn’t actually generally available today.

9:09AM: Azure Cosmos DB for PostgreSQL lets you run your Postgres apps with the data stored inside Cosmos DB, without having to change your apps. No applause here – it just isn’t the right conference for it. Was worth the 30 seconds he spent on it, but no more than that. It’s a neat idea though.

9:10AM: Azure Synapse Link for SQL is generally available, which makes your ETL processes way easier. Evidently they’ve just added a Schedule Mode, smaller compute capacity support, vNet support, and full support for datetime data types. I read that list and go, “Uh, you tried to launch an ETL product without those things?!?”

9:14AM: Azure Data Factory SAP CDC Connector in general availability, Azure Synapse Mapping Data Flow for M365 Graph is in public preview.

9:26AM: The WiFi in the conference center died for a while. I wrote a few updates, but lost them in the WiFi outage. <sigh>

9:27AM: Hugo Kornelis is fighting AML, so there’s a heart-touching video playing about #TeamHugo.

9:30AM: It’s a wrap! Off to today’s sessions.

This week, a lot of the questions you posted at just need pointers to resources at other places. Welcome to the Read This, Watch This series of answers.

Don’t Blame Anthony: Our developers prefer writing TSQL queries directly in their .NET code rather than writing sprocs and calling them. What are the pros / cons to this approach?

Read this.

Divakar: Is there any formula based on number of processor cores that I can set for Maxdop for a sql server

Read this.

Mr. No: What is your favorite NOSQL database?

Read this.

Dan Griswold: How would you manage access to SQL Server Agent jobs. Our development team shares jobs and they all want to have access to run and modify them. Of course, sysadmin is the only way to grant that privilege. So, we created a sql account and gave them all the pswd. Any better ideas?

Read this.

Jr Wannabe DBA: Hi Brent, once in a lifetime I saw a new index blocking insert operations to a table. What are the reasons it can happen? The support team removed the index before I was able to take a look at it, but it looks like the index created some restriction on what can be inserted. Thx.

Watch this video and this video.

John Martin: A query is imbedded in a compiled program. Is there a way to force it to use a specific index? I can’t change the query. It often picks the wrong index even if we’ve updated statistics and rebuilt the index

Read this.

Magnús: Do you have any scenarios where you like to use the QUERY_OPTIMIZER_COMPATIBILITY_LEVEL query hint?

Watch this video. 

Barney Fife: Worried about unmanaged / unlicensed SQL servers running under someone’s desk. What are some good ways to automate discovery of all SQL servers on the company network?

Try the Microsoft Assessment and Planning Toolkit.

ScenarioFromRealWorld: You log on to a SQL Server to help your client. You notice that almost every process/connection in the SQL Server is using the sa account. Both locally and also from clients through the network. Would you say anything regarding this, and if so, what would you say to your client?

Read this and this.

Leif Hole: Hi Brent ! Is there a noticeable performance difference between cluster index on one vs two integer columns ?

Watch this video.

Dominique B: What’s the white (moto) helmet’s story ?

Read this.

MyFriend: Hi Brent. sp_BlitzIndex (latest) is reporting “Index Hoarder: Unused NC Index with High Writes” for some indexes that have 0 Reads in Usage stats. But have numbers in “singleton lookups” and/or “scans/seeks” in Op Stats. Why is that & would you still consider them safe to drop?

Watch this.

Ramil: Hi Brent! Is there a tool to replicate production load on other environment? For example, we make backup or snapshot of a database, then we start to record all transactions with sessions. Then we replicate this load on other environment as it was on prod.

Read this.

MyFriend: Hi Brent Have you ever “fixed” Parameter sniffing problems, because of spills to disk, by turning Adaptive Memory grants off in SqlServer2019? And if so, what would be the main drawback in doing so?

Watch this.

CliveP: Hi Brent. Can you let me know how you would handle an Aggressive under index warning on a table where there are no missing recommendations and I don’t have access to the application code?

Watch this.

I chuckle a lot when I see data professionals banging their heads against a wall on a hard problem, Googling their brains out, frustrated because they’re not finding any easy answers.

You’ve been consuming my free material for years. You’ve worked hard to polish your knives, to continuously get better.

But for some reason, you think you’re too smart for training classes.

  • 01:18 Chris May: Within an index, if you can guarantee unique selectivity with 2 key columns, is there a fundamental difference between adding an extra key column or an included column? Which would you typically prefer?
  • 03:15 Pyjamarama: Hello Brent. In one of our customers our User databases (Greek_CI_AI) are in different Collation than TempDB (Latin1_General_CI_AS). What is the best way to fix that? (We prefer to keep the CI_AI). Thanx!
  • 04:41 Maksim Bondarenko: What would you do first if two sql servers with the same version and CU generate almoust identical execution plan with one exception? Second server generates one additional block (in my case it is Index Spool after Cl scan) and that’s why 10 times work faster. Thx
  • 05:47 Piotr Rasputin: What’s your opinion of azure vm host caching for SQL vm’s?
  • 07:30 Peter: What does your op love ones at home say when you talk like Clippy all the time? 🙂 Thanks for all the knowledge you share with us all

  • 11:49 chris: With a SQL Server built on a virtual machine on VMWare is there a way to determine CPU and/or memory pressure on the host without having access to VCentre?
  • 12:38 LockedUp: I have a proc that is causing deadlocks. I have tracked it down to an Update statement with a ROWLOCK hint. Could the ROWLOCK hint be causing the deadlock? Update statement is well written and indexed, not sure why ROWLOCK is even needed.
  • 14:24 Leonard: What is your opinion of the SQL Server data collector? Any good for performance troubleshooting?
  • 15:12 Maciej: Hi Brent, do you have a missing feature in SSMS and/or SQL Server that you treat (at this point) as an old friend? 😉 In addition if you could “influence” Microsoft to implement one which one would it be?
  • 17:11 Leif Hole: Hi Brent ! Really enjoy your “think like the engine” and the fundamentals ! My friend have this theory that Mr. Codd meant that all joins between tables is the best way of getting data. Never denormalize ! Is there any thumb of rules when it comes to denormalizing ?
  • 18:09 chris: I understood Azure SQL DB was always current; however, when I view the compatibility level of some of my databases they’re not current. Is it up to me to change this? Any gotchas with doing so?

Y’all post questions at, upvote the ones you’d like to see me cover, and then I talk through ’em.

There’s a slight problem with this episode: I forgot to hit the Record Questions button in PollGab, so I can’t quickly/easily generate the list of questions we covered. If you asked a highly voted question in the last week or so, it’s probably in here.

Is There a Bug in SQL Server’s MAXDOP Calculation? (Update: Yes!)

Configuration Settings

I think I’ve found a bug in SQL Server setup’s MAXDOP calculation, and I need you to take a second look. Setup is recommending MAXDOP 8:

Setup recommending MAXDOP 8

Which is odd, because this is running on an AWS i3.16xlarge with 2 sockets, 2 NUMA nodes, 32 logical processors per node, 64 logical processors altogether. In this screenshot, I’ve laid Task Manager alongside setup so you can see what I mean:

If you click on the “Configure the max degree of parallelism” link in setup, it says:

In this case, the SQL Server has multiple NUMA nodes, with greater than 16 logical processors per node – that’s the last line of the screenshot. In that line, Microsoft says MAXDOP should be half of the number of logical processors with a max of 16 – so 16.

But it’s recommending 8. Hmm.

Is Soft-NUMA the culprit? No.

After SQL Server finishes installation and starts up, the error log shows automatic soft-NUMA kicked in because NUMA nodes had more than 8 physical cores:

SQL Server errorlog

So it created 4 NUMA nodes, each with 16 logical processors. In that case, maybe the setup calculation was taking that configuration into account – 4 nodes, each with 16 cores. In that case, let’s revisit the guidance:

Now, the number in play is the 3rd line of the screenshot – “Less than or equal to 16 logical processors per NUMA node.” In that case, we’re supposed to keep MAXDOP at or below the # of logical processors per NUMA node.

Now, technically 8 is below 16 – but where the heck is 8 coming from? Why not, uh, 16, or 4, or 12, or for that matter, 2?

I’m guessing I’m missing something obvious, but I asked on Twitter, and nobody figured it out. Worst case, either the documentation is wrong, or setup is wrong, there’s some kind of other recommendation that isn’t shown in setup – like maybe there’s a hidden max of MAXDOP 8 during setup?

So, what’d I miss?

Update 1: one of the smartest SQL Server folks I know, Joe Obbish, writes that he thinks it may not be documented anywhere. It’d be cool if we did get it documented, though – whatever logic is good enough for setup should be good enough for KB 2806535, so users can make that same decision as their VM sizes grow.

Mystery Solved: Yep, There’s a Mismatch.

Microsoft employee Sean Gallardy answered that setup uses a different formula than the documentation recommends:

Step 1: Calculate Hardware NUMA and Soft NUMA
Step 2: Decide whether Hardware or Soft NUMA will be used
Step 3: Divide the total logical processors by the NUMA used
Step 4: If > 15 LPs/NUMA, MAXDop = (LPs/NUMA)/2, otherwise MAXDop = LPs/NUMA

Which means that if you have:

  • 14 logical processors per NUMA node: MAXDOP will be set to 14
  • 16 logical processors per NUMA node: MAXDOP will be set to 8

<sigh> That doesn’t make any sense, but it is what it is. It’s probably always been this way since SQL Server 2016 “fixed” MAXDOP by setting it during setup.

Post your questions at and upvote the ones you’d like to see me discuss during my live streams. This week, I took a break from working on my PASS Summit sessions in order to chat:

Here’s what we covered:

  • 00:00 Start
  • 00:32 Jeremy: We have an older web app we’re going to be rewriting to use microservices. We’ll also be migrating it from on-prem to Azure. Our dev consultant is recommending we use Postgres rather than MS SQL Server to save money. What are your thoughts on moving from MS SQL to Postgres?

  • 04:30 Kimberly Hathaway: Brent – battling sysadmins in my org. They want Veeam backups for all SQL svrs & not SQL backups. Claim is point in time DB recovery with Veeam. I say logs are not getting truncated so Veeam is not talking to SQL. Can you point me to a doc that will support this.
  • 06:19 Cats_Everywhere : Hey Brent, I’m planning a new SQL Server build. I expect the Business people want this server to exist for 8-10 years. Are there any good arguments (business people would love) to persuade them to stick to a 5 year max? I picked 5 years due to Patching support from MS.

Learn the Fundamentals of TempDB for Free This Week.


Every weekday during the month of October, one of the modules from my Fundamentals classes will be absolutely free to watch. But you gotta watch it that day – you snooze, you lose.

For this week’s TempDB class, you don’t have hands-on labs, but if you want to follow along with the demos, I’ll be using the same 50GB Stack Overflow 2013 database we used during the first two weeks.

Eagle-eyed readers will note that this isn’t all of the modules from each class, nor is it all of my Fundamentals classes. That’s because this whole thing is a diabolical mind trick, dear reader. I aim to get you hooked on the quality of my online training, and then come November 1st, when my annual Black Friday sale starts, you’ll be ready to get out your wallet – or your boss’s wallet – to get a Recorded Class Season Pass: Fundamentals, or Mastering, or the Level 2 Bundle when they go on sale.

Let’s Hang Out in Person at the PASS Summit Next Month.


I’m so excited to see everybody again at the PASS Data Community Summit in Seattle on November 14-18.


Here’s the crazy part: I’m not going to attend a single session. Not one. (Well, except the ones I’m teaching, and the keynotes.)

Instead, I’m gonna spend every single conference hour hanging out in the Community Zone, talking to people in the hallways, and catching up with people that I haven’t seen for a couple of years. People like you.

Weird, right? Especially since this is a release year for SQL Server 2022, and there are probably gonna be a lot of good sessions from Microsoft. You know what? I don’t care. I don’t. I’ll watch the recordings and read the slide decks later. When I’m in Seattle, I’m gonna have the experience that I missed so much.

I wanna see y’all again, hear what you’ve been up to, take pictures with each other.

If you can’t come in person, it’s also a hybrid event: you can either attend in-person in Seattle, or online via live streaming. If you attend online, PASS is recording the live stream, and you’ll be able to re-watch it during the week of the conference. This is super helpful for folks who have an emergency at work, have to drop off the call, and want to be able to catch up on what they’ve missed.

Here are my sessions.

Pre-Conference Workshop: Mastering Parameter Sniffing – You’re a database developer or DBA with at least 5 years experience performance tuning queries and indexes. You already know you have parameter sniffing issues, and now you need to figure out how to fix it. In this one-day class, you’ll learn how to reduce the blast radius with index changes, query tuning, and database-level settings. You’ll also see firsthand how SQL Server 2017, 2019, and 2022 try to reduce it with adaptive joins, adaptive memory grants, automatic tuning, and caching multiple plans. Attendees will also get one year access to the full 3-day Mastering Parameter Sniffing recordings, too! That’s a $395 value, and it’s free with your workshop admission. (You’ll get the access in class.)

Everything You Know About Parallelism Is Wrong. Just because you see parallelism icons on execution plans doesn’t mean the query went parallel. SQL Server doesn’t load-balance work across CPU cores. CXPACKET isn’t a problem you fix by changing MAXDOP. Hell, even the term “MAXDOP” doesn’t mean what people think it means. It’s not that SQL Server’s parallelism is bad, it’s just not what you think it is.

Fragmentation Explained in 10 Minutes. Short, fast-paced lightning talks require difficult choices for presenters. If things go even the slightest bit off the rails, you are completely screwed. You have to viciously edit down your material to get the right points across, and no more than that. Then, you have to rehearse, rehearse, rehearse to get the timing right. The last lightning talk I did at PASS, I was wearing a Bob Dylan costume, a wig, and a harmonica. This year, no costumes – just aiming for ambitious delivery.

Register now. Let’s hang out. I miss you.

That just got weird, and I don’t even care.

Updated First Responder Kit and Consultant Toolkit for October 2022

First Responder Kit Updates

It’s fall – time to review your SQL Servers’ configurations, health, backups, and performance before fall turns into fail. To help, we’ve got a new version of the First Responder Kit.

How I Use the First Responder Kit
Wanna watch me use it? Take the class.

To get the new version:

Consultant Toolkit Changes

I updated it to this month’s First Responder Kit, but no changes to querymanifest.json or the spreadsheet. If you’ve customized those, no changes are necessary this month: just copy your spreadsheet and querymanifest.json into the new release’s folder.

sp_AllNightLog Changes

  • Fix: now works when system database collations don’t match. (#3132, thanks Bjorn Nordblom.)

sp_Blitz Changes

  • Enhancement: check for most recent log backup using DBCC DBINFO rather than msdb. This way, it works even if the log backups were taken on another AG replica. (#3143, thanks SQL Lambert.)
  • Enhancement: warn about additional dangerous 3rd party modules. (#3149 and #3150, thanks David Wiseman.)
  • Enhancement: works on Amazon RDS even if the server name has been changed. (#3146, thanks Bo Anderson.)

sp_BlitzFirst Changes

  • Fix: returns the Azure SQL DB compatibility that was broken in the last release. (#3139, thanks SJOrderDIRECT.)
  • Fix: even more compatibility for Azure SQL DB. (#3130, thanks DMonlineUK.)

sp_BlitzQueryStore Changes

sp_DatabaseRestore Changes

  • If you use sp_DatabaseRestore and you have servers in different time zones, we’d appreciate your help testing #3113. It’s not included in this release because no one has tested it yet. If you can test the StopAt parameter with different time zones and report back in that issue (not here in the comments) about how it worked, that’d be great.

Bonus changes: Anthony Green kept up the tireless work of keeping the SQL Server versions file up to date.

For Support

When you have questions about how the tools work, talk with the community in the #FirstResponderKit Slack channel. Be patient: it’s staffed by volunteers with day jobs. If it’s your first time in the community Slack, get started here.

When you find a bug or want something changed, read the file.

When you have a question about what the scripts found, first make sure you read the “More Details” URL for any warning you find. We put a lot of work into documentation, and we wouldn’t want someone to yell at you to go read the fine manual. After that, when you’ve still got questions about how something works in SQL Server, post a question at and the community (that includes me!) will help. Include exact errors and any applicable screenshots, your SQL Server version number (including the build #), and the version of the tool you’re working with.
