Changes S3 Intelligent-Tiering adds support for Archive and Deep Archive Access tiers; S3 Replication adds replication metrics and failure notifications, brings feature parity for delete marker replication
Lists the S3 Intelligent-Tiering configuration from the specified bucket.
The S3 Intelligent-Tiering storage class is designed to optimize storage costs by automatically moving data to the most cost-effective storage access tier, without additional operational overhead. S3 Intelligent-Tiering delivers automatic cost savings by moving data between access tiers, when access patterns change.
The S3 Intelligent-Tiering storage class is suitable for objects larger than 128 KB that you plan to store for at least 30 days. If the size of an object is less than 128 KB, it is not eligible for auto-tiering. Smaller objects can be stored, but they are always charged at the frequent access tier rates in the S3 Intelligent-Tiering storage class.
If you delete an object before the end of the 30-day minimum storage duration period, you are charged for 30 days. For more information, see Storage class for automatically optimizing frequently and infrequently accessed objects .

{'ArchiveStatus': 'ARCHIVE_ACCESS | DEEP_ARCHIVE_ACCESS'}
The HEAD operation retrieves metadata from an object without returning the object itself. This operation is useful if you're only interested in an object's metadata. To use HEAD, you must have READ access to the object.
A HEAD request has the same options as a GET operation on an object. The response is identical to the GET response except that there is no response body.
If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you retrieve the metadata from the object, you must use the following headers:
x-amz-server-side-encryption-customer-algorithm
x-amz-server-side-encryption-customer-key
x-amz-server-side-encryption-customer-key-MD5
For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) .
Note
Encryption request headers, like x-amz-server-side-encryption , should not be sent for GET requests if your object uses server-side encryption with CMKs stored in AWS KMS (SSE-KMS) or server-side encryption with Amazon S3–managed encryption keys (SSE-S3). If your object does use these types of keys, you’ll get an HTTP 400 BadRequest error.
Request headers are limited to 8 KB in size. For more information, see Common Request Headers .
Consider the following when using request headers:
Consideration 1 – If both of the If-Match and If-Unmodified-Since headers are present in the request as follows:
If-Match condition evaluates to true , and;
If-Unmodified-Since condition evaluates to false ;
Then Amazon S3 returns 200 OK and the data requested.
Consideration 2 – If both of the If-None-Match and If-Modified-Since headers are present in the request as follows:
If-None-Match condition evaluates to false , and;
If-Modified-Since condition evaluates to true ;
Then Amazon S3 returns the 304 Not Modified response code.
For more information about conditional requests, see RFC 7232 .
Permissions
You need the s3:GetObject permission for this operation. For more information, see Specifying Permissions in a Policy . If the object you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.
If you have the s3:ListBucket permission on the bucket, Amazon S3 returns an HTTP status code 404 ("no such key") error.
If you don’t have the s3:ListBucket permission, Amazon S3 returns an HTTP status code 403 ("access denied") error.
The following operation is related to HeadObject :

string
[REQUIRED]
The name of the bucket containing the object.
When using this API with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName -AccountId .s3-accesspoint.*Region* .amazonaws.com. When using this operation with an access point through the AWS SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using Access Points in the Amazon Simple Storage Service Developer Guide .
When using this API with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName -AccountId .*outpostID* .s3-outposts.*Region* .amazonaws.com. When using this operation using S3 on Outposts through the AWS SDKs, you provide the Outposts bucket ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see Using S3 on Outposts in the Amazon Simple Storage Service Developer Guide .
string
Return the object only if its entity tag (ETag) is the same as the one specified, otherwise return a 412 (precondition failed).
datetime
Return the object only if it has been modified since the specified time, otherwise return a 304 (not modified).
string
Return the object only if its entity tag (ETag) is different from the one specified, otherwise return a 304 (not modified).
datetime
Return the object only if it has not been modified since the specified time, otherwise return a 412 (precondition failed).
string
[REQUIRED]
The object key.
string
Downloads the specified range bytes of an object. For more information about the HTTP Range header, see http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.35 .
Note
Amazon S3 doesn't support retrieving multiple ranges of data per GET request.
string
VersionId used to reference a specific version of the object.
string
Specifies the algorithm to use to when encrypting the object (for example, AES256).
bytes
Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.
string
Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.
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 Requestor Pays Buckets in the Amazon S3 Developer Guide .
integer
Part number of the object being read. This is a positive integer between 1 and 10,000. Effectively performs a 'ranged' HEAD request for the part specified. Useful querying about the size of the part and the number of parts in this object.
string
The account id of the expected bucket owner. If the bucket is owned by a different account, the request will fail with an HTTP 403 (Access Denied) error.

Response Structure
(dict) --
DeleteMarker (boolean) --
Specifies whether the object retrieved was (true) or was not (false) a Delete Marker. If false, this response header does not appear in the response.
AcceptRanges (string) --
Indicates that a range of bytes was specified.
Expiration (string) --
If the object expiration is configured (see PUT Bucket lifecycle), the response includes this header. It includes the expiry-date and rule-id key-value pairs providing object expiration information. The value of the rule-id is URL encoded.
Restore (string) --
If the object is an archived object (an object whose storage class is GLACIER), the response includes this header if either the archive restoration is in progress (see RestoreObject or an archive copy is already restored.
If an archive copy is already restored, the header value indicates when Amazon S3 is scheduled to delete the object copy. For example:
x-amz-restore: ongoing-request="false", expiry-date="Fri, 23 Dec 2012 00:00:00 GMT"
If the object restoration is in progress, the header returns the value ongoing-request="true" .

If present, specifies the ID of the AWS Key Management Service (AWS KMS) symmetric customer managed customer master key (CMK) that was used for the object.
StorageClass (string) --
Provides storage class information of the object. Amazon S3 returns this header for all objects except for S3 Standard storage class objects.
For more information, see Storage Classes .
RequestCharged (string) --
If present, indicates that the requester was successfully charged for the request.
ReplicationStatus (string) --
Amazon S3 can return this header if your request involves a bucket that is either a source or destination in a replication rule.
In replication, you have a source bucket on which you configure replication and destination bucket where Amazon S3 stores object replicas. When you request an object (GetObject ) or object metadata (HeadObject ) from these buckets, Amazon S3 will return the x-amz-replication-status header in the response as follows:
If requesting an object from the source bucket — Amazon S3 will return the x-amz-replication-status header if the object in your request is eligible for replication. For example, suppose that in your replication configuration, you specify object prefix TaxDocs requesting Amazon S3 to replicate objects with key prefix TaxDocs . Any objects you upload with this key name prefix, for example TaxDocs/document1.pdf , are eligible for replication. For any object request with this key name prefix, Amazon S3 will return the x-amz-replication-status header with value PENDING, COMPLETED or FAILED indicating object replication status.
If requesting an object from the destination bucket — Amazon S3 will return the x-amz-replication-status header with value REPLICA if the object in your request is a replica that Amazon S3 created.
For more information, see Replication .
PartsCount (integer) --
The count of parts this object has.
ObjectLockMode (string) --
The Object Lock mode, if any, that's in effect for this object. This header is only returned if the requester has the s3:GetObjectRetention permission. For more information about S3 Object Lock, see Object Lock .
ObjectLockRetainUntilDate (datetime) --
The date and time when the Object Lock retention period expires. This header is only returned if the requester has the s3:GetObjectRetention permission.
