『Embulk』に見るモダンJavaの実践的テクニック ～並列分散処理システムの実装手法～The document discusses implementing an event-driven architecture using events instead of synchronous APIs. It explains that events decouple services by allowing them to communicate asynchronously through a centralized event routing system. This loose coupling makes services more independent and resilient, as failures in downstream services do not block upstream ones. It also improves scalability a
