Today after fighting with designing a view that let me create a clustered index on it (indexed views — also known as materialized views — are awesome in the right context!), I kept running into the same… Using indexed views? Don’t forget this important tip.
In 2016 I created the Max Server Memory Matrix as a guide for configuring the maximum amount of memory that should be assigned to SQL Server, using an algorithm developed by Jonathan Kehayias. SQL Server 2019… Better SQL Server memory defaults in 2019
SQL Server 2019 is still in preview as I write this, but I wanted to point out a new feature that Microsoft has added to SQL Server Setup, on the Windows version. On the Database… Better SQL Server CPU defaults in 2019
