Company News
2 Comments

You’ve been working with Microsoft SQL Server for a couple of years, and you know a little bit about TempDB. You’ve heard that temp tables and table variables have different performance characteristics than regular user database tables, and you’ve heard that you’re supposed to have multiple data files.

You’re wondering what exactly goes on behind the scenes.

This class is for curious folks who want to learn:

  • What uses TempDB, and how that affects performance: not just temp tables and table variables, but also triggers, cursors, sorting indexes, workspace spills, the version store, and more
  • How to host TempDB depending on how you use it: understanding what goes in the log file, the data files, why the number of data files matter, and whether your particular workload should be on SAN, local storage, or ephemeral storage, and why
  • How to monitor it: after you understand what uses it and how to host it, you need to keep tabs on how its performance changes over time using DMVs, Perfmon counters, and the First Responder Kit scripts

This course is 90% demos: the only slides are the introductions at the start of the day, illustrations to support a few topics, and the recap at the end of the day. The rest of the time, we’ll be working in SQL Server Management Studio. Roll up your sleeves and join me!

Join me live, for free, on Tuesday 8:00-16:00 UTC in Europe-friendly times, and again Wednesday in Americas-friendly times, 9AM-5PM Eastern. Register here.
