Testing–Faking a delay in SQL Server

To test the timeout settings of my application, I needed a query that exceeds a certain time.

This was not that hard to achieve in SQL Server thanks to the WAITFOR statement. This statement blocks the execution of a batch, stored procedure, or transaction until a specified time or time interval is reached, or a specified statement modifies or returns at least one row.


----Delay for 10 seconds
WAITFOR DELAY '000:00:10'
SELECT 'Hello finally!'
GO

A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t
