Re: Collaboration using Event Sourcing

Does being offline mean that there are multiple copies of the same domain implementation active, each with a separate database? There are database solutions that sync offline copies, that could be a better approach (reinventing a wheel).

Otherwise a messaging system that allows catchup and guarantees delivery. Usually it is not smart to try and solve such situations with your own code.

They will also sometimes be offline.  I envision a rich domain with events and the use of event streaming.  Events would occur locally per client and then need to be published.  The subscribers would need to process the events as an idempotent operation.  The clients need to be eventually consistent.  Can an asynchronous event publish/subscribe model work here?  Does it make sense?  I would think some sort of callback would be in order so that events are not continuously sent over and over with the use of some sort of projection snapshot?
