I had the pleasure to have a conversation with Brent on PHP Annotated about event sourcing.
We talked about event sourcing in general, benefits, difficulties, and how we're using it in production.
When event sourcing, the stream of events is your source of truth where all data is derived from. A promise often made in event sourcing pitches is that you can destroy your data and rebuild (replay) it at any time. In my experience, it's a lot more nuanced than that.
