In addition to PutObject, OSS also provides the multipart upload mode. You can upload files in the multipart upload mode in the following scenarios (but not limited to the following):
- Resumable upload must be supported.
- The files to be uploaded are larger than 100 MB.
- The network conditions are poor, and the connection with the OSS server is frequently disconnected.
- Before a file is uploaded, the size of the file cannot be determined.
