object_versions — Boto3 Docs 1.26.83 documentation

This action enables you to delete multiple objects from a bucket using a single HTTP request. If you know the object keys that you want to delete, then this action provides a suitable alternative to sending individual delete requests, reducing per-request overhead.

The request contains a list of up to 1000 keys that you want to delete. In the XML, you provide the object key names, and optionally, version IDs if you want to delete a specific version of the object from a versioning-enabled bucket. For each key, Amazon S3 performs a delete action and returns the result of that delete, success, or failure, in the response. Note that if the object specified in the request is not found, Amazon S3 returns the result as deleted.

The action supports two modes for the response: verbose and quiet. By default, the action uses verbose mode in which the response includes the result of deletion of each key in your request. In quiet mode the response includes only keys where the delete action encountered an error. For a successful deletion, the action does not return any information about the delete in the response body.

When performing this action on an MFA Delete enabled bucket, that attempts to delete any versioned objects, you must include an MFA token. If you do not provide one, the entire request will fail, even if there are non-versioned objects you are trying to delete. If you provide an invalid token, whether there are versioned keys in the request or not, the entire Multi-Object Delete request will fail. For information about MFA Delete, see MFA Delete.

Finally, the Content-MD5 header is required for all Multi-Object Delete requests. Amazon S3 uses the header value to ensure that your request body has not been altered in transit.

Request Syntax

response = bucket.object_versions.delete( MFA='string', RequestPayer='requester', BypassGovernanceRetention=True|False, ExpectedBucketOwner='string', ChecksumAlgorithm='CRC32'|'CRC32C'|'SHA1'|'SHA256')

Parameters

• MFA (string) -- The concatenation of the authentication device's serial number, a space, and the value that is displayed on your authentication device. Required to permanently delete a versioned object if versioning is configured with MFA delete enabled.
• RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
• BypassGovernanceRetention (boolean) -- Specifies whether you want to delete this object even if it has a Governance-type Object Lock in place. To use this header, you must have the s3:BypassGovernanceRetention permission.
• ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
• ChecksumAlgorithm (string) --

  Indicates the algorithm used to create the checksum for the object when using the SDK. This header will not provide any additional functionality if not using the SDK. When sending this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request . For more information, see Checking object integrity in the Amazon S3 User Guide .

  If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

  This checksum algorithm must be the same for all parts and it match the checksum value supplied in the CreateMultipartUpload request.

Response Structure

• (dict) --

  • Deleted (list) --

    Container element for a successful delete. It identifies the object that was successfully deleted.

  • RequestCharged (string) --

    If present, indicates that the requester was successfully charged for the request.

  • Errors (list) --

    Container for a failed delete action that describes the object that Amazon S3 attempted to delete and the error it encountered.
