Read Part 1: MediatR vs MassTransit Mediator - Differences

The MassTransit Mediator implementation is more powerful than MediatR implementation, but also more complicate to use. Unit Testing a MassTransit Consumer is not a nice experience.

In this article I will propose some techniques to simplify the MassTransit Consumer and to make them look as straight forward as a MediatR handler.

Case study

We will study a very common use case (the most common use case which I can think of):

Why mediator?

In a ASP.NET Web application. You don't need mediator

• If you prefers to make controlers depends directly to the Application Codes instead of indirectly via the Mediator.
• If you prefers to make a normal ASP.NET Web Application instead of a Mediator Application

Frankly it is not a Bad choice, no need to use a Mediator framework or make a Mediator Application just because everyone did.. Though, There are benefits in making a Mediator Application:

• Event sourcing (Messages broadcast), CQS pattern..
• Decouple the Controler (presentation) from Application codes, so that you could swap the presentation technology. For eg, if you make a "MassTransit" application, then you can swap the presentation layer to Mediator or RabbitMQ, or Grpc.. => you are not to be sticked with or limited by ASP.NET presentation => but rather sticked with and limited by your mediator framework!

It's true that swapoff -a is a silver bullet in most cases, however, certain k8s setups may really require swap. For instance, I've got a very small and cheap VM with just 1GB RAM, which I use for a personal GitLab Runner that rarely handles short CI/CD tasks. If I increase the size of the machine, I'll be paying more for a resource that's 99% idle. If I disable swap, npm install and other scripts inside the buid pods may hang because they require quite a lot of memory, although for short periods of time. Thus, a single-node kubeadm cluster with gitlab runner chart and swap is what suits me best.

Here is how I could get my mini-cluster up and running:

kubeadm reset 

## ↓ see explanation below
sed -i '9s/^/Environment="KUBELET_EXTRA_ARGS=--fail-swap-on=false"\n/' /etc/systemd/system/kubelet.service.d/10-kubeadm.conf
