The Data Bus design pattern aims to provide a centralized communication channel through which various components of a system can exchange data without being directly connected, thus promoting loose coupling and enhancing scalability and maintainability.
An Event Aggregator is a design pattern used for handling events in a system. It centralizes the event handling logic, making it easier to manage and maintain. The Event Aggregator design pattern aims to decouple event generation from event handling. This design pattern collects events from multiple sources and routes them to the appropriate handlers.
The Idempotent Consumer pattern is used to handle duplicate messages in distributed systems, ensuring that multiple processing of the same message does not cause undesired side effects. This pattern guarantees that the same message can be processed repeatedly with the same outcome, which is critical in ensuring reliable communication and data consistency in systems where message duplicates are possible.
