I wrote a guest article for an IT consultancy on Azure SQL Database, more specifically DTUs and vCore options. At a high level I discuss what both options are, the differences and what you should select. Hopefully you will find it useful. Please see the link below:
Sometimes I like to see and know what SQL server is doing under certain operations and recently I wrote an extended events script to see what sort of I/O patterns my query was doing (This is a fun post). The important event here is sqlserver.file_read_completed.
I clear cache and let the fun begin.
I would like to share a link to my Azure SQL Database Stairway series hosted over at SQLServerCentral.
As stated on the website a stairway guide is a series focused on a single topic and is arranged into no more than a dozen easily-navigable tutorials that we call ‘steps’. Each step is the length of a typical magazine tutorial, and emphasizes practical, hands-on learning, with just enough background theory to help you understand the topic.
If you decide to use IP addresses to control what services have access to your Azure SQL Database, then understanding firewall rules are important. Within this important area you have the ability to create firewall rules that are scoped to the database or server level as shown below.
This is kind of a follow up from my last blog post about a scale down request issue. (https://blobeater.blog/2018/11/07/azure-sql-database-aborting-scale-request/) I was confused, so confused that I ended up logging a support request with Microsoft. The issue was I wanted to scale down a database from S1 to Basic however it would take hours for a 1GB database. Obviously something was up, but what?
