Abort Multipart Upload

Last updated: 2019-10-23 17:13:09



This API (Abort Multipart Upload) is used to abort a multipart upload and delete the uploaded parts. When you call this API, if there is a request that is uploading a part using the Upload Parts API, the request will fail. If the UploadId does not exist, 404 NoSuchUpload will be returned.

It is recommended that you either complete or abort the multipart upload in a timely manner, as the parts that have been uploaded but not completed will take up storage space and incur storage fees.
