How does Kotlin handle large-scale event-driven architecture?

Kotlin uses coroutines and message brokers like Kafka to handle event-driven systems.

Event-driven architectures decouple services using asynchronous message passing. Kotlin coroutines handle event consumption efficiently without blocking threads. Systems like Kafka or RabbitMQ act as event backbones. Proper design ensures idempotent consumers, retry-safe processing, and backpressure handling using Flow or reactive streams.
