Multipart Upload#

We recommend uploading large files in parts. This allows you to upload file parts in parallel and avoid the need to restart uploading of the entire file if the process fails. After uploading, the whole object is assembled from the parts.

Multipart upload is recommended when the file size exceeds 100 MB. Each part of the file (except for the last) must not be less than 5 MB.

CreateMultipartUpload#

Initiates multipart uploading.

The request returns Upload, the multipart upload ID, which must be used in all subsequent operations on the multipart object.

UploadPart#

Uploads a part of the object into the specified bucket. You must specify the part number and upload ID in the request. Individual parts can be uploaded in any order.

The response returns an ETag. It, along with the part number, must be specified when assembling the object from parts.

AbortMultipartUpload#

Aborts the multipart upload. Uploaded parts are deleted from the object storage.

If any parts are being uploaded at the time when you run the operation, then you may need to re-run it to delete the newly uploaded parts. To verify that all parts have been deleted, run ListParts.
