> Atlan supports the [S3 extraction method](/apps/connectors/messaging/on-premises-event-buses/how-tos/set-up-on-premises-kafka-access) for fetching metadata from Aiven Kafka. This method uses Atlan's kafka-extractor tool to fetch metadata.

:::warning Who can do this?
 You will probably need your [Aiven Kafka administrator](https://docs.aiven.io/docs/products/kafka/concepts/acl#acl-permission-mapping) to complete these steps - you may not have access yourself.
