Thanks all for joining me for two sessions at SQLSaturday Minnesota 2023, and for great feedback and questions. I'm always a big supporter of SQLSaturday events whenever I can and I was honored to speak virtually to this conference again!
Slide decks for my two presentations are available for download on GitHub.
A late-breaking change that arrived in SQL Server 2022 is an important one that could be a new line item in your health checks.
Starting with SQL Server 2022, transaction log file growth events up to 64 MB in size can benefit from instant file initialization (IFI). As usual, the transaction log is otherwise unable to benefit from instant file initialization.
This should be a big performance improvement if your transaction log files unexpectedly grow. Of course, you should try to avoid autogrowth events altogether.
There's lots more cool new stuff in SQL Server 2022, too.
The default autogrowth rate for transaction log files in new databases is already 64 MB. Unless you have specific needs for your workload, consider keeping this default now, considering the dramatic advantage IFI brings to file space allocation.
In both your database and log files you should proactively pre-allocate enough space to avoid autogrowth events anyway. Regularly monitor the space in database files to prevent autogrowth events. The proactive DBA, outside of busy hours, should grow database data and log files manually, so that they do not autogrow during busy hours.
And whatever you do, don't shrink your data and log files, only to have them autogrow again the next business cycle.
Of course, this only works if your SQL Server instance is capable of instant file initialization. The SQL Server service account must be granted the Perform Volume Maintenance Tasks permission in Local Security Policy on the Windows server. A quick script works for modern versions of SQL Server:

Looking forward to speaking in Seattle at next week's PASS Data Community Summit by Redgate. I'll be speaking both as a representative of my role on the Microsoft Database Docs team and as a data professional.
On Wednesday Nov 16, you'll find me in the main exhibit hall in the Microsoft Booth Theater (#217) giving a presentation on contributing to Microsoft Docs, at 530pmPT. Hope to see you there. If prizes are available to give away, you know I'll give em up.
On Thursday afternoon, Christine and I are presenting together on a topic that is important to us, Ethics in Modern Data. I bring my years as a data professional and Christine brings her experience and a Masters degree in Organization Psychology, combined with our passion for history, civil rights, and technology. We'll be discussing issues ripped from the news headlines and in history. These will frame a discussion about bias in data collection and analysis, and our responsibilities as data professionals. I hope we spark your interest in these important topics that shape our data industry.
On Friday morning, I'll be presenting a full hour on Database Docs. We'll discuss how they work behind the scenes and how you can contribute to open-source docs via GitHub. This will also be an interactive feedback panel for the entire Docs platform inside Microsoft Learn. Hope to see you there, inspire you to contribute to the Docs that the entire data community uses daily, and answer any questions.
