The Query Tuning Trick You Should Use More: Pagination

When I'm tuning queries, the normal answer is to make the query perform better - either via changing the T-SQL, adding hints, or adding indexes so that the data's better prepared for the query.

However, sometimes when I'm looking at the output of sp_BlitzCache, I scroll across to the Average Rows column and double-check that the query's actually returning a reasonable number of rows out in the wild.

Microsoft Fabric Has a New Service Status Page.

I've been pretty vocal here on the blog and on social media about the reliability problems with Microsoft Fabric. Today, I've got good news: Microsoft released a new Fabric status page and a known issues page, something that really does take guts given the current reliability situation. The status page still appears to be manually updated, not automated, but at least it acknowledges outages like how SQL endpoints are currently returning incorrect query results:

[Video] Job Options: Zooming Out to See the Big Picture

One of my readers asked me to give a 30-minute talk to their company's internal employees discussing the job market at large. The target audience was technical people of all disciplines - not just database administrators, but all kinds of people who worked with technology.

My goal with the talk was to help people think about lots of possible next-steps in their career journey. I wanted to show how the skills they've already developed might be useful in jobs they hadn't thought about before.
