SQL Login Overhead in SQL Server 2025

Published 2026-07-13 by Kevin Feasel

Sean Gallardy has a wonderful rant:

There were a few emails about login times so I figured it warranted a blog post. Strap in, this one goes sideways fast.

Some people noted that the amount of time to log in with a SQL Login in SQL Server 2025 all of a sudden took longer. This is clearly stated in the Docs, though the way it is written is documented is problematic.

As Sean mentions, this is on purpose and it is good. Yeah, the amount of time it takes to log in using SQL authenticated accounts in SQL Server 2025 is higher. That’s because the mechanism to log in is now considerably more secure than it was before. And let’s be honest: how frequently are you logging into SQL Server? What percentage of your processing time does that take? Because if the answer is “a large percentage,” that sounds like a job for connection pooling or revising the calling application.

Checking Query Options from Query Store

Published 2026-07-13 by Kevin Feasel

Michael Bourgon sets ANSI_PADDING:

We know that SQL Server can cache multiple query plans for the same query based on the SET_OPTIONS for that query, and that SSMS doesn’t have the same options as the standard library. (https://www.sommarskog.se/query-plan-mysteries.html). He even includes a chart!

My initial comment was “Michael Bourgon sets XACT_ABORT” but that’s actually not one of the list, so I had to change it for the sake of correctness even though I think it was funnier in its original guise.

Direct Lake Mode Benefits in Power BI

Published 2026-07-13 by Kevin Feasel

Chris Webb lays out the pros:

This is a blog post I’ve been meaning to write for a long time. Since Fabric launched there has been a lot of focus on Direct Lake mode in Power BI and a lot of people used it because it was the cool new thing. Arguably, we at Microsoft have been guilty of telling people to use it because it was the cool new thing without properly explaining what the benefits are of using it. Direct Lake doesn’t completely replace other storage modes: in a recent post I talked about when Import/DirectQuery composite models are the best choice; Marco wrote a good article on Direct Lake vs Import mode which makes the case for the continuing relevance of Import mode for many scenarios. So what are the main benefits of using Direct Lake mode?

Performing a Lakehouse Table Health Check

Published 2026-07-13 by Kevin Feasel

Jon Lunn looks at a stored procedure:

Microsoft have rolled out a new ‘sys’ stored procedure called ‘sys.sp_get_table_health_metrics’ for checking the health of your tables in your Lakehouse. And it outputs a lot of metrics looking at the state of your table and anomaly detection in them.

What does it check for?

Click through for that answer, as well as some of the things you should watch for in the procedure results, and what you can do if it does catch something.
