bro you have the knack for this. Short, concise and really informative. Keep this format and keep more of them coming! Thanks.

I watched a 30-minute video but couldn't comprehend it. However, you were able to explain it to me in just 3 minutes, and I am grateful.

I've already gone through alot of material and implemented CQRS in my project and came across this video. If I'd have seen this I would have saved a couple of hours looking at so many blogs and videos this really sums up everything gives you usescases examples everything.

We need more videos. the simplicity of your explanations is the glory

[DodaGarcia]

What a wonderful channel!! I'm glad I found it, it's a fantastic resource to send to less technical colleagues about the concepts being used in the code.

Very underated channel, I hope it takes off
Here before 3k subs

[hammadiazaiez]

honestly, your are very underrated :/ Your are helping me alot with these videos! Thanks !

Insane 2nd video of the channel, keep them coming, I WANT MORE KNOWLEDGE

[Rolan]

Yet another great video!!!
Please keep them coming !!!

[rini]

holy shit thats what a clear explanation is!

[GenShepherd]

Thanks for the video, wish you more subscribers!

Love your explanation thank you - I'm still on the fence about this paradigm. Again it feels like it was put together by some journeymen devs who were bored and felt they needed to invent something nobody asked for and probably another layer of bloat in microservice hell architecture. We developers often cite how complicated web development has become and its because of things like this.

Brilliant video, informative and concise. I would suggest Unit Of Work video. I really appreciate your efforts. 👍

please avoid the background music...it's irritating.

Visual Description is very pleasant. Keep it coming

This is fine for atomic streams of operations that don't conflict received in order. Like 80% of website style transaction. However it does NOT scale horizontally. It provides, no, it refuses basic concurrency monitor controls and basics like "Test and set". Splitting a "Dequeue" operation into 2 concurrent/ordered operations leaves you wide open to race conditions, dead locks and I cannot see how this scales horizontally to accomodate increasing loads.

You should improve your video release schedule :)

This background music is of very poor quality, looks like it was recompressed multiple times. Please consider removing it. Otherwise great content. Subscribed.
