🔑Events and commands are two important components of event-driven architecture.
💡Events and commands can be communicated as event notifications and messages.
🌟Event-driven architecture allows for decoupling and inverting dependencies.
🔒Events are immutable and can be processed in parallel.
🔄Event-driven architecture supports data replication and parallel processing.
What is the difference between an event and a command?
—An event is something that happens, while a command is an order or request for a response.
Can events and commands be communicated as messages?
—Yes, events can be communicated as event notifications, and commands can be communicated as messages.
What are the benefits of event-driven architecture?
—Event-driven architecture provides benefits such as scalability, decoupling, and parallel processing.
When should event-driven architecture be used?
—Event-driven architecture is useful when scalability is more important than performance, when data replication is required, and when decoupling and parallel processing are needed.
What are the characteristics of events in event-driven architecture?
—Events are immutable, can be processed in parallel, and can be persisted for future retrieval.
