Very good video, but I think Mass Transit + RabbitMQ would deserve and need more content. I hope you will do some follow up videos for this.

Good video and useful to explain the subject matter. I used to agree but honestly if you want to go at scale you need to move to the 2.0 (ish) of queue tech which are the cloud native queues (rabbit types) and logs (think kafka) in gcp, azure and aws. These systems provide much deeper serverless options that can scale up with little hassle. (chief arch, fortune 5)

Great video! So RabbitMQ is the lightweight database/queue persisting the events. You hook up Mass Transit to connect to this 'queue' and whenever an event is persisted to the queue the appropriate mass transit event handler will consume it. Is this an alternative to the transactional outbox pattern where you raise events to the DB and process them with a background service? They are similar. I can see the benefit of both for sure. This one feels more lightweight than the TransactionalOutbox -> Background Service reading jobs. But maybe that's because I am considering that with the raising of domain events and the aggregate root unit of work commits to db.

@MilanJovanovicTech

Жыл бұрын

You can think of a queue as a pipe. Something comes in on one end, and comes out on the other end. It's different from an outbox since it's another external system to your database. It increases the surface area for things to fail. I'm planning another video soon about Sagas and it'll cover queues a little bit more

Hi Milan! Can I ask you something? When you use records in C# is it much simple and less code with only the constructor and pass the values through the constructor instead of properties? or this is just a clean-written code? After all, records are read-only I know. Maybe I'm wrong. Can't be modified additionally in another place with accessing some property. Thanks for the videos 🙂. Поздрав од Македонија. 😉

I find it simpler, that's why. Plus I get immutability, etc. By no means a convention, but an approach I found useful. MassTransit also recommends using interfaces for message contracts. But this is annoying in that you'll have to make implementations on sending side, so double code. Pozdrav iz Niša :)

Is OK to connect to the Message Queue / RabbitMQ from a client running javascript? Or would it be a design failure, an overkill, (too much load/ package size, etc.) and should translate to REST apis / websocket instead for the small clients?
