Event-based system: Uklon practice [ukr]
Talk presentation
Event-based systems are becoming more and more popular every year. At the same time, the challenges and accidental complexity we have as a result can be more complex than the problem we need to solve. Numerous architectural patterns (EDA, orchestration vs choreography, EventSourcing, etc.) can lead to unexpected traps.
Using the example of technical solutions implemented in Uklon(traffic jams, custom driver matching, driver arrival time updates), let's look at these patterns from a practical point of view.
