Use client tools like `mc` to set and listen for event notifications using the [`event` sub-command](https://docs.min.io/docs/minio-client-complete-guide#events). MinIO SDK's [`BucketNotification` APIs](https://docs.min.io/docs/golang-client-api-reference#SetBucketNotification) can also be used. The notification message MinIO sends to publish an event is a JSON message with the following [structure](https://docs.aws.amazon.com/AmazonS3/latest/dev/notification-content-structure.html).
Bucket events can be published to the following targets:

MinIO supports persistent event store. The persistent store will backup events when the MQTT broker goes offline and replays it when the broker comes back online. The event store can be configured by setting the directory path in `queueDir` field and the maximum limit of events in the queueDir in `queueLimit` field. For eg, the `queueDir` can be `/home/events` and `queueLimit` can be `1000`. By default, the `queueLimit` is set to 10000.
