Overview
EDA is a design pattern where the flow of the program is determined by events—such as user actions, sensor outputs, or messages from other programs. It enables highly decoupled and scalable systems.
Key Components
- Event Producers: Components that generate events.
- Event Consumers: Components that listen for and react to events.
- Event Channels: The infrastructure (like message queues) that carries events from producers to consumers.
Benefits
- Asynchronous Communication: Producers don't wait for consumers to process events.
- Scalability: Consumers can be scaled independently based on event volume.
- Flexibility: New consumers can be added without modifying producers.
