Hello Javier, It's a bit hard to answer on event design questions when we discuss "Entity" and "Event" :-) But in general these events should have some meaning, not only "AttributeUpdated" - as in "BughtItem", "ShippedThingy", "ConfirmedPayment".
Play around with the granularity of your events, maybe you're being too fine grained? These are good books about DDD in general, so if you haven't already you might want to check them out: * "THE Book": http://www.amazon.co.uk/Domain-driven-Design-Tackling-Complexity-Software/dp/0321125215/ref=sr_1_2?ie=UTF8&qid=1405338610&sr=8-2&keywords=ddd * http://www.amazon.co.uk/Implementing-Domain-Driven-Design-Vaughn-Vernon/dp/0321834577/ref=sr_1_1?ie=UTF8&qid=1405338610&sr=8-1&keywords=ddd :-) On Mon, Jul 14, 2014 at 11:56 AM, Javier Santos Paniego <jsan...@tecsisa.com > wrote: > Hi, > > I have a modifiable entity with lots of attributes that might be > values(like dates) or entity references : > > case class Entity(attribute1: String, attribute2: Int, ..., attribute22: > Boolean) > > My question is: If I follow DDD and Event sourcing philosophy, should I > have an action and an event for each modifiable attribute? > Maybe I could avoid writing some boilerplate if I used macros (action > 'UpdateAttribute(attributename, value)' and event > 'AttributeUpdated(attributename,value)') but, is this a sane practise? > Is there any other simplier way to do that? > > Thanks for any advise, > > Javier > > -- > >>>>>>>>>> Read the docs: http://akka.io/docs/ > >>>>>>>>>> Check the FAQ: > http://doc.akka.io/docs/akka/current/additional/faq.html > >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user > --- > You received this message because you are subscribed to the Google Groups > "Akka User List" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to akka-user+unsubscr...@googlegroups.com. > To post to this group, send email to akka-user@googlegroups.com. > Visit this group at http://groups.google.com/group/akka-user. > For more options, visit https://groups.google.com/d/optout. > -- Cheers, Konrad 'ktoso' Malawski hAkker @ Typesafe <http://typesafe.com> -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
