Upload file

Create metadata information and get an uploadUrl for a file.

To upload the file, send an HTTP PUT request to the uploadUrl from the response, with the relevant 'Content-Type' and 'Content-Length' headers.

If the uploadUrl contains the string '/v1/files/gcs_proxy/', you can make a Google Cloud Storage (GCS) resumable upload request as documented in https://cloud.google.com/storage/docs/json_api/v1/how-tos/resumable-upload.

The uploadUrl expires after one week. Any file info entry that does not have the actual file uploaded within one week will be automatically deleted.

Note: The uploadUrl from initFileUpload supports files smaller than 5 GiB.

The initMultiPartUpload and completeMultiPartUpload endpoints provides an alternative way to upload files, both small and large, up to 1 TiB in size. These endpoints exposes a uniform multipart upload API for all cloud vendor environments for CDF. Optionally parallel part uploads can be used, for faster uploads.

Request throttling

This endpoint is subject to the new throttling policy, which enforces limits on both request rate and concurrency. For more details, please refer to the Files resource documentation.

Request
query Parameters
overwrite
boolean
Default: false

If 'overwrite' is set to true, and the POST body content specifies a 'externalId' field, fields for the file found for externalId can be overwritten. The default setting is false.

If metadata is included in the request body, all of the original metadata will be overwritten. The actual file will be overwritten after a successful upload with the uploadUrl from the response. If there is no successful upload, the current file contents will be kept.

File-Asset mappings only change if explicitly stated in the assetIds field of the POST json body. Do not set assetIds in request body if you want to keep the current file-asset mappings.
