常見問題
What is event-driven microservices architecture?
Services publish events about state changes so other services can react asynchronously.
Why use an event bus?
It decouples event producers from the services that consume their events.
Should every service use events?
No. Use events for asynchronous state changes; direct requests can still suit immediate queries or commands.
