Interface TransferSpec_SourceBucket

Credentials for accessing the source bucket. These credentials must have list and get permissions. This parameter must be specified only during create operations.

The endpoint must be in the form of a URL, starting with the protocol (https), followed by the endpoint address without a trailing slash. Example: https://storage.us-central1.nebius.cloud

Limiters applied to source bucket operations. These limits include all operations required for transfer (HeadObject, GetObject, ListObjects). For details about which operations are used, see public documentation: http://docs.nebius.com/object-storage/transfer/quickstart#background.

Note: Since the service performs comparable request volumes and data transfers to both source and destination, these limits will indirectly constrain destination operations as well.

Prefix to filter objects in the source bucket. Only objects whose keys start with this prefix will be transferred. During transfer, the resulting object key in the destination bucket is computed by removing source.prefix from the original key and then prepending destination.prefix (if provided). Important: This transformation may result in an empty object key or one that exceeds allowed length limits. Use prefixes that guarantee valid resulting object keys for your objects after transformation.
