MinIO supports all the exchanges available in [RabbitMQ](https://www.rabbitmq.com/). For this setup, we are using `fanout` exchange.

MinIO also sends with the notifications two headers: `minio-bucket` and `minio-event`. An exchange using the type "headers" can use this information to route the notifications to proper queues.
