The architecture from hell. Hard to debug. Why didn't my service pick up that event? Error handling. What happens with the state if a service throws an exception? Resource hog. How do I map/reduce all these events into a state?
I do like events. They go into my elk stack where I can look at pretty graphs which gives me a story of how my system behaves over time.
