When to use Light Events vs. Rich Events in Event-Driven Architectures

Choosing between light and rich events in event-driven architectures involves trade-offs. Light events, containing minimal information, are cost-efficient but may increase complexity for subscribers needing additional data. Rich events include more information, reducing the need for extra calls by subscribers but increasing data transfer and storage costs. Domain events, often benefitting from light events, are shared within the same domain, while integration events, suited for rich events, are shared across domains. Understanding these differences helps optimize event design and system efficiency.
