Event Driven Architecture (EDA) is a highly scalable and extensible architectural style where a service publishes an event, and other services can react to it by consuming it and executing their business logic. The payload of an event depends on the specific use case, such as order placement in a food delivery platform. In some cases, only the order ID is included in the event, while in others, additional data from different microservices may be included. The important aspect is that the event payload should be designed in a way that ensures the latest and accurate information is available to the consumer services.
