We are living in a true golden age of knowledge, to have free access to such valuable information at a snap of our fingertips. If only more people noticed.

At 53' I think he missed the point on the benefits combining Event Sourcing with a GraphDb. I don't write my data just in a Graph Db as I use it for data analysis. Event Sourcing pattern is what helps in these cases as it gives the possibility of build and re-build graphs (or any other read-model) as needed.

[@RtoipKa]

Can you explain why you would need full history of events and not last state to rebuild those graphs?

[@riccardodinuzzo9778]

@@RtoipKa are you interested to the last state right now or one week ago? No matter which, the "current" state is built right into the read model applying the past events in near real time or on demand

[@RtoipKa]

@@riccardodinuzzo9778 so its only if you are interested in past. But your post suggested that it gives you some special features when creating different read models which I think is not true.

[@riccardodinuzzo9778]

@@RtoipKa so it's not "only" if you are interested in the past. That is to say how the "current" state can be relative. There are other benefits off course as for example building different read models for different stores (graph db, doc db, ml/ai pipeline....), scale your read models as you need over multiple instances and more

[@RtoipKa]

@@riccardodinuzzo9778 but you can get all that without event sourcing.

Remember to fix his name in the video as well.

[@illyakysil8005]

There is a typo in the title of the video - he's Udi Dahan, not Daham.

[@dmsanz_youtube]

the video itself has the name mistaken under Udi's picture

[@illyakysil8005]

@@dmsanz_youtube At least his slides are correct :)

[@ddd_eu]

Thanks for the heads up.

[@mexo100]

Udi killed event sourcing conference and he has done it well!

[@Avlec1000]

Great talk, pragmatic as always :)

[@Bosslogq]

He and Uncle Bob has very similar voices 😀

ha! I didn't notice until I read your comment. I agree, they have very similar voices but only when presenting.
