The object storage bucket that contains the dataset data source.
The namespace of the bucket that contains the dataset data source.
A common path prefix shared by the objects that make up the dataset. Except for the CSV file type, records are not generated for the objects whose names exactly match with the prefix.
Specifies the dataset location in object storage. This requires that all records are in this bucket, and under this prefix. We do not support a dataset with objects in arbitrary locations across buckets or prefixes.
