Hi Richard,

I'm really struggling to understand what an event sourced DDD design
looks like with Akka persistence. Are any complete examples on the
way (perhaps in Activator) ?
In particular, some of Vaughn Vernon's stuff seems to suggest
aggregate *instances* as actors (which I find a bit confusing and hard
to relate to supervision hierarchies) whereas the old eventsourced
example had actors as aggregate *processors*, but also included
in-memory domain and STM in the mix.
akka-persistence completely leaves it to the application how state is
organized (processor per aggregate type, aggregate instance or whatever
...) and referenced (var, STM ref, ...). Giving a general recommandation
here would be too restrictive IMO. It really depends on the specific
requirements what makes most sense.
(Part of) the examples in akka-sample-persistence will become activator
templates but we don't have a complete DDD reference application yet.
Would be great to see some contributions here :-)
I very much enjoyed this series, but it's not using Akka:
http://blog.zilverline.com/2011/02/01/towards-an-immutable-domain-model-introduction-part-1/
I eventually found this example mentioned (but not linked) in the Akka
Persistence documentation:
https://github.com/akka/akka/tree/master/akka-samples/akka-sample-persistence
but it's not saving state on a per-aggregate basis.
Thanks in advance for any enlightenment.
