In this episode Adam and Martin recap the Workshop from November 30th and talk about the different topics that were brought up. This includes not using upcasters in event sourcing thanks to Yordis Prieto, keeping things simple, the discipline it takes to unlearn old lessons and not reuse any models across the workflows in your system, how this negatively affects coupling and other topics: - Yor...

In this episode of the Event Modeling and Event Sourcing Podcast, Adam Dymitruk and Martin Dilger introduce the podcast and where the topics will come from in the future episodes. The debut of Martin's book at #2 on LeanPub is discussed and why it's such a draw to people in the industry. A discussion of breaking the Domain Driven Design Aggregate pattern is what the show ends with and sets up t...
I think so far the only time I hade multiple events in one handler was stuff like adding a tombstone event for example, which is more like a technical thing. If you have multiple business events coming from one handler then it could be a sign that you are missing out on some concept. Would be awesome to look at some examples.
@@majormartintibor even tombstone events can be handled outside that command handler. You can trigger a processor for that.
Really interesting discussions guys. There is a lot to learn!
Thanks for another great episode! I loved that Snoopy mug as well :)
I am really enjoying this series, and looking forward to the possibility of another workshop this year (I found out about Saturday's too late to be there). Keep up the good work!
Regarding the lookup of product name when you only have the product id, isn't that something where view-model composition could come into play? Rather than bloating the shopping cart read model with data that it doesn't own, you can compose the final read model that is returned back to the user in some kind of UI composition layer where each logical boundary (here shopping cart and product) can participate in the composition of the read model. Any thoughts?
That's subjective so we always repeat. Share nothing except the events that change state.
Always a pleasure to listen to you guys.
Your speaker ratio is way off. Not quite sure why this disturbs me... Guess I was expecting more of a dialogue.

Thanks for the podcast, I appreciate it. Though I found the part on security a bit too high-level. I think I got the main points but it still feels a bit abstract.
yes definitely, we will pick this topic up in the future again. It´s hard to navigate the topics between too high level and too deep and still keep it at a maximum length of 30 minutes. We are getting better at it hopefully over time
Yes!!
Good content! Looking forward to the next episode.
Great initiative! Are you guys going to be on Spotify?
yes!
Liked, subscribed and set notification bell to all :) Plus a comment to help with YT algorithm.
Enjoyed this episode.
