Azure DevOps–Why is my database so big?

When preparing an Azure DevOps Server migration, the customer asked me why there Azure Devops databases grew so fast.

There are 2 queries that can help you answer this question.

  • The first query gives a general overview of the different parts:

The output of the first query returned the following results in this case:

Owner BlobSizeInMb
VersionCVersionControl 64992.008339881835
FileContainer 59599.479797363281
TeamTest 44243.018857001953
WorkItemTracking 23674.237445831054
CodeSense 989.945262908203
ProcessTemplate 125.949053763671
Generic 54.288738250000
  • The second query goes in more detail to differentiate between source control and build:

The output of the second query returned the following results in this case:

FileContainerOwner TotalSizeInMb
Build 56681.754142760742

Git

pipelines://b

They started storing there build artifacts in the database, this explained why there Azure DevOps databases exploded so much.

.NET 8–Keyed/Named Services

A feature that a lot of IoC container libraries support but that was missing in the default DI container provided by Microsoft is the support for Keyed or Named Services. This feature allows you to register the same type multiple times using different names, allowing you to resolve a specific instance based on the circumstances. Although there is some controversy if supporting this feature is a good idea or not, it certainly can be handy. To support this feature a new interface IKeyedServiceProvider got introduced in .NET 8 providing 2 new methods on our ServiceProvider instance: object? GetKeyedService(Type serviceType, object? serviceKey); object GetRequiredKeyedService(Type serviceType, object? serviceKey); To use it, we need to register our service using one of the new extension methods: Resolving the service can be done either through the FromKeyedServices attribute: or by injecting the IKeyedServiceProvider interface and calling the GetRequiredKeyedServic...

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. 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...
