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.

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us.

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
