GCP CSV source - Atoti Hub

The bucket and prefix to read from are set through the bucket and prefix properties. The DLC ensures that only files within that source can be loaded.

To use this source, a Storage bean must be defined. A default one can be used by enabling dlc.create-default-cloud-client.gcp.
