In addition to the PUT Object interface, the OSS also provides the Multipart Upload mode for you to upload files. You can apply the Multipart Upload mode in the following scenarios (but not limited to the following):

  • Breakpoint upload need to 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 broken.
  • Before a file is uploaded, the size of the file cannot be determined.
