Time modeling is always difficult, as well as implementing business flows inside complex domains. Long lived transactions which span multiple bounded contexts, possible success and failure scenarios are even more difficult to model, test and implement. Fortunately, we have an answer to this problem! Multiple messages, events, aggregates and bounded contexts? Not a problem, Saga pattern may be very helpful… During this talk you will learn how to model long running business processes which affect many regions inside domains, what are the best possible use-cases and when to avoid sagas.
