Business value

Users now have reduced complexity for developers making upload calls, chunking upload of all uploads to improve performance, and streaming download of files to improve performance.

Feature details

The following changes have been made to file and image data types:

Upload

  • Single APIs can be used for all uploads so users no longer need to use separate APIs for files under 1 MB and files over 16 MB.

  • Automated chunking removes the need for developers to specify file chunking through different APIs for the start, middle, and end.

    Note

    Previous chunking APIs will continue to exist to support existing implementations.

Download

  • Downloads can be streamed through use of an SAS API.
  • Previous chunking APIs will continue to exist to support existing implementations.

Users who handle file and image transactions through the client UI will get these benefits by default with no additional code changes needed. If you are making direct API calls, you can choose to use the new APIs and replace your existing calls as needed. To learn more, go to File attributes and Upload image data.
