Abort Multipart Upload

Last updated: 2019-12-16 18:09:10



This API is used to abort a multipart upload and delete the uploaded parts. If you call this API and there is an Upload Part request that is using the multipart upload, the request will fail. If the uploadId does not exist, 404 NoSuchUpload will be returned.

It is recommended to either complete or abort a multipart upload as early as possible, as the uploaded parts of an incomplete multipart upload will take up storage capacity and incur storage fees.
