Video – Creating Azure SQL Database

A quick 2 minute upload (with sound, my voice) showing you how easy it is to create an Azure SQL Database using the Azure portal and then using SSMS (SQL Server Management Studio) to connect to it.

Scaling SQL Elastic Pools

There are a few ways to scale a SQL elastic pool. For this blog post I show you how to scale up. It can be done via the Azure portal and Azure PowerShell but not T-SQL.

I would say the PowerShell route is the easiest. Connect to your account and issue the below code. Here I am going from a 100 edtu pool to a massive 2000 edtu pool whilst tweaking the min/max setting.

Tuning Azure SQL Elastic Pools

The below image is a beautiful picture, now it could be worse. The red line and the green line could peak at the same time and for a very long time or the blue line could behave the same as the red line and peak at the same time as the green line. Regardless of the situation the point of this blog post is when you are hitting your eDTU (elastic database transaction unit) limits within your elastic pools, tune your queries and do not knee jerk and just scale up (straightaway that is).

New Improved Azure Elastic Jobs

There is a new way to setup Azure elastic jobs to run against a target group of databases (targeting an elastic pool). I actually found the process quite messy ( especially when trying to setup all the security access via T-SQL). Setting it up via the Azure portal is not currently an option. The first element remains the same, the need to create a “Job database”. This is the central database, think of it as the master. (Not really the master database in SQL Server but holds a lot of metadata etc) Then you need to define the group (usually the elastic pool), create credentials for access and then the job itself.

Sizing your Azure SQL Database

Do you want to identify the correct Service Tier and Compute Size ( was once known as performance level) for your Azure SQL Database? How would you go about it? Would you use the DTU (Database Transaction Unit) calculator? What about the new pricing model vCore? How would you translate you current on-premises workload to the cloud?

SQL Server – max server memory

Another re-post of a video from last year, this time showing you an in-built protection of setting max server memory for your SQL Server. You can clearly see that if you enter a silly figure such as 50 MB, the minimum memory amount allowable for max server memory is 128 MB. You will see SSMS (SQL Server Management Studio) change it to 128MB.

Azure SQL Data Warehouse Query Store

I personally think that query store has been a fantastic feature. I find myself using it for query performance troubleshooting (plan regressions is a big one). This has always been available since SQL Server 2016 and even Azure SQL Database but now Microsoft have made it available for Azure SQL Data Warehouse (DW).

If you connect to the Azure SQL DW via SQL Server Management Studio (SSMS) there is no Query Store Node (for the version, I was checking 17.9.1). I was even wondering if it was on by default?
