Automatic Stats Updates Don’t Always Invalidate Cached Plans

Normally, when SQL Server updates statistics on an object, it invalidates the cached plans that rely on that statistic as well. That's why you'll see recompiles happen after stats updates: SQL Server knows the stats have changed, so it's a good time to build new execution plans based on the changes in the data.

However, updates to system-created stats don't necessarily cause plan recompiles.

Maybe You Shouldn’t Even Be Using Clustering or AGs.

Sandra Delany (LinkedIn) wrote a well-thought-out blog post called, "Should a SQL Server DBA Know Windows Clustering?" She's got about 20 years of DBA experience, and she works for Straight Path (a firm I respect) as a consultant. You can probably guess based on her background that yes, she believes you should know how to set up, configure, and troubleshoot Windows clustering. It's a good post, and you should read it.

Thoughts on PASS’s Bankruptcy, Redgate’s Acquisition, and Private Equity

A private equity (PE) company recently acquired the majority of Redgate Software, the current owners of the PASS Data Community Summit and SQLServerCentral. Everybody in tech has private equity stories, some good, some terribad. Private equity hands money to companies not out of generosity, but because they believe they can turn it into even more money…

[Video] Office Hours in Kyoto, Japan

Kyoto feels like a timeless, classic version of historical Japan with quiet tree-lined streets, giant temples, and bubbling brooks. It's the exact opposite of last week's experience in noisy Osaka! Last year, I filmed in Kyoto outside a temple, and this year, I'm at another temple just after New Year's, the time when Japanese folks traditionally go to visit their many gorgeous temples.

Should There Be Ads in SSMS?

Some folks are seeing an ad at the top of their SSMS v22, like this one reported in the feedback site:

Today, Microsoft's using this to test ads for an upcoming conference. Interesting that they give deeper discounts to Reddit readers as opposed to SSMS users, but I digress. Tomorrow, they might be pushing SQL Server 2025 upgrades, or Microsoft Fabric, or Copilot, or whatever.

[Video] Office Hours in Osaka, Japan

The Dotonbori area of Osaka is like a video game version of Japan: wild, over-the-top neon signs, awesome street food, cool street markets, Kabuki theater on a revolving stage, and more. It's very touristy, but as touristy places go, it's fantastic. Last year when I was here, I filmed Office Hours at the river, but this time around let's go into one of the side streets where the food vendors gather.

Your Favorite Posts From This Year

Reading is fundamental, and fundamentally, here are the 2025 blog posts that y'all read the most this year. (This list doesn't include the most popular timeless posts overall.)

10. Free Spring Training Webcasts - I've noticed that people have near-zero interest these days in paying to attend live online classes, but they're still really interested in free ones, and they still pay for recorded classes. Weird. I'm guessing that's a Zoom fatigue thing.
