This is to support optimistic concurrency

Narvalex commented 7 years ago

I understand, but, shouldn't it be optional? Since there are lots of event sourcing implementations that does not wraps the optimistic concurrency check all the way from the read model, but from the aggregate hydration, like the Microsoft's Patterns a Practice CQRS Journey?

It is optional. The value is nullable.

Fair enough. Thanks
