Supported Schemes¶
According to the DRS Specification, object bytes can be downloaded by multiple access method types. The DRS client supports byte download by different types, indicated by the type parameter of AccessMethod objects in a DRSObject’s access_methods array. These access method types correspond to URI schemes. For each DRSObject, the client will attempt to download object bytes by each supported scheme in sequence, until the file has been successfully downloaded, or until all download options have been exhausted without success.
Currently, the DRS client supports download by 2 URI schemes/access method types:
| Scheme | Description |
|---|---|
| gs | Google Cloud Storage |
| https | Hypertext Transfer Protocol Secure |
