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!

Clear NuGet Cache

Before continuting to the next step, let's clear some nuget caches that might get in the way.

dotnet nuget locals all --clear

WebApplication and WebApplicationBuilder

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
