Learning all about the SQL Server Plan Cache
Get the Slides and T-SQL Scripts Shown in the Webcast
In case you didn't know, I've been doing a series of webinars on the topic of SQL query tuning, approximately once every two weeks. In these webinars, I go very heavy on the demos and, in all but the most recent webinar, eschew slides entirely.
The latest episode, broadcast live on Tuesday 10-Nov-2015, went in-depth into the SQL Server plan cache, the area of SQL Server memory reserved for handling T-SQL code and related objects. Since the topic was more elaborate and abstract than the three previous episodes, I wrote a supplementary slide deck along with the usual boatload of demos. We covered four main topics in the webinar:
- Situations that cause 'bloat' in the plan cache;
- Scenarios that cause the SQL Server optimizer to choose a suboptimal plan;
- Problems with parameter sniffing; and,
- Causes for inappropriate recompiles.
