abort_multipart_upload

S3.Client.abort_multipart_upload(**kwargs)

This action aborts a multipart upload. After a multipart upload is aborted, no additional parts can be uploaded using that upload ID. The storage consumed by any previously uploaded parts will be freed. However, if any part uploads are currently in progress, those part uploads might or might not succeed. As a result, it might be necessary to abort a given multipart upload multiple times in order to completely free all storage consumed by all parts.

To verify that all parts have been removed, so you don’t get charged for the part storage, you should call the ListParts action and ensure that the parts list is empty.

For information about permissions required to use the multipart upload, see Multipart Upload and Permissions.
