 | `blob_type`                  | Specify the desired blob type. Supported values: `appendblob`, `blockblob`.                                                                                                                                                  | `appendblob`                  |
 | `auto_create_container`      | If `container_name` doesn't exist in the remote service, enabling this option handles the exception and auto-creates the container.                                                                                          | `on`                          |
 | `path`                       | Optional. The path to store your blobs. If your blob name is `myblob`, specify subdirectories for storage using `path`. For example, setting `path` to `/logs/kubernetes` will store your blob in `/logs/kubernetes/myblob`. | _none_                        |
-| `compress`                   | Sets payload compression in network transfer. Supported value: `gzip`                                                                                                                                                        | _none_                        |
-| `compress_blob`              | Enables GZIP compression in the final `blockblob` file. This option isn't compatible when `blob_type` = `appendblob`.                                                                                                        | _none_                        |
+| `compress`                   | Sets payload compression in network transfer. Supported values: `gzip`, `zstd`.                                                                                                                                              | _none_                        |
+| `compress_blob`              | Enables compression in the final `blockblob` file. Defaults to GZIP and inherits the codec from `compress` when that option is set. This option isn't compatible when `blob_type` = `appendblob`.                            | _none_                        |
 | `emulator_mode`              | To send data to an Azure emulator service like [Azurite](https://github.com/Azure/Azurite), enable this option to format the requests in the expected format.                                                                | `off`                         |
 | `endpoint`                   | When using an emulator, this option lets you specify the absolute HTTP address of such service. For example, `http://127.0.0.1:10000`.                                                                                       | _none_                        |
 | `tls`                        | Enable or disable TLS encryption. Azure service requires this to be set to `on`.                                                                                                                                             | `off`                         |
