Tempdb Improvements in 2019
- QotD Question
In this article we cover many different questions about the SQL Server TempDB database to give a better understanding of what is and what it is used for.
In this article we look at a new feature in SQL Server 2019 that can help improve TempDB performance.
When you are setting up a new SQL Server machine you need to determine how big you should make tempdb. To make sure you size tempdb appropriately you should monitor the tempdb space usage. If there are autogrowth events occurring after you have recycled SQL Server than you might want to increase the size of your tempdb data files. If tempdb never uses most of the tempdb space, then you might want to consider decreasing the size of tempdb.
Have you ever checked the size of the SQL Server tempdb after restarting SQL Server to find that it's reset? Simon Liew explains this behaviour.
