Is it possible to have an example with EventSourcing?

I know it is difficult to implement the EventSourcing on the Legacy.

What are the changes to the level of the reading model and loading the aggregate?

The old tables are modified by the event headphones (Event emitted by the aggregate)
The aggregate is loaded by rerunning past events.

What else ?

Hello,

I made another sandbox that works with ES some months ago : https://github.com/tyx/cqrs-php-sandbox

But I have not try yet to implement ES on legacy so quite hard to give an example.

Anyway I don't see any blocking point as you mention.

The legacy table could became your view/snapshot. So you could build your aggregate by running new events from this snapshot.

Thank you !

The file organization is free! This gives me ideas to remodel my projects and have a better separation.
