As I announced in the last part, our CQRS/ES journey is almost finished! But before it happens we need to take care of read side of our application. However, before we move forward to the implementation, it’s worthwhile to explain why do we need a read side? After all, we have an excellent data source called Event Store which allows us to reconstruct every domain object in our system.

I also don’t like to write my opinions about the sessions (in some rare cases I do write them anyway). And yet here I’m writing about #programistok 2016. Why?
