Hangfire–Change polling interval

In modern .NET applications, background processing plays a crucial role in handling tasks that don't need to be executed immediately, such as sending emails, processing large datasets, or scheduling recurring jobs. A library I like to use to manage background tasks in .NET is Hangfire, thanks to its simplicity, flexibility, and wide range of storage options.

As these background tasks can be scheduled in the future, some kind of storage needs to be configured where Hangfire keeps all the information related to background job processing. Out of the box multiple storage systems are supported, one of them being SQL Server.

Although using SQL Server can be a convenient option to use as the main storage for your Hangfire, it comes with one big disadvantage: 

  • Polling is used to fetch new jobs.

This has 2 consequences:

  • It increases the load on your SQL server instance
  • The time to pickup a new job and execute it  is signifcantly longer(here is a comparison with Redis from the documentation):


If it is ok to have some additional delay, you can configure a slower QueuePolInterval(the default is TimeSpan.Zero for Hangfire 1.7 or newer):

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...

.NET 9 - Goodbye sln!

Although the csproj file evolved and simplified a lot over time, the Visual Studio solution file (.sln) remained an ugly file format full of magic GUIDs. With the latest .NET 9 SDK(9.0.200), we finally got an alternative; a new XML-based solution file(.slnx) got introduced in preview. So say goodbye to this ugly sln file: And meet his better looking slnx brother instead: To use this feature we first have to enable it: Go to Tools -> Options -> Environment -> Preview Features Check the checkbox next to Use Solution File Persistence Model Now we can migrate an existing sln file to slnx using the following command: dotnet sln migrate AICalculator.sln .slnx file D:\Projects\Test\AICalculator\AICalculator.slnx generated. Or create a new Visual Studio solution using the slnx format: dotnet new sln --format slnx The template "Solution File" was created successfully. The new format is not yet recognized by VSCode but it does work in Jetbr...
