I really want to simplify writing backend logic and implement everything like functions that reacts on some events and produce another one's. This is a very very looks like, Actor Model (Akka) plus Redux's Reduces: We have just a bunch of a state changing rules and they can be executed reliably and with decent performance. Something very simple (for example for Build Server): Build Failed (Event) -> Assign responsible user for a crash -> Send Notification -> Deliver Notification via user's configured notification systems (email, push, sms..) This is a Event Sourcing, but event sourcing works well only for one part of the platform - write side, but reader side is sometimes too hard to implement. Sometimes there are a problems with eventual consistency and you actually need to wait while some of the reducers in chain will process this event and starting from this point everything became toooo slow to develop and you basically start to redevelop the wheel - this is just a database engine de-factor. Meh.
