Container for the parameters to the UploadMultipartPart operation. This operation uploads a part of an archive. You can upload archive parts in any order. You can also upload them in parallel. You can upload up to 10,000 parts for a multipart upload.
Amazon Glacier rejects your upload part request if any of the following conditions is true:
SHA256 tree hash does not matchTo ensure that part data is not corrupted in transmission, you compute a SHA256 tree hash of the part and include it in your request. Upon receiving the part data, Amazon S3 Glacier also computes a SHA256 tree hash. If these hash values don't match, the operation fails. For information about computing a SHA256 tree hash, see Computing Checksums.
Part size does not matchThe size of each part except the last must match the size specified in the corresponding InitiateMultipartUpload request. The size of the last part must be the same size as, or smaller than, the specified size.
If you upload a part whose size is smaller than the part size you specified in your initiate multipart upload request and that part is not the last part, then the upload part request will succeed. However, the subsequent Complete Multipart Upload request will fail.
Range does not alignThe byte range value in the request does not align with the part size specified in the corresponding initiate request. For example, if you specify a part size of 4194304 bytes (4 MB), then 0 to 4194303 bytes (4 MB - 1) and 4194304 (4 MB) to 8388607 (8 MB - 1) are valid part ranges. However, if you set a range value of 2 MB to 6 MB, the range does not align with the part size and the upload will fail.
This operation is idempotent. If you upload the same part multiple times, the data included in the most recent request overwrites the previously uploaded data.
An AWS account has full permission to perform all operations (actions). However, AWS Identity and Access Management (IAM) users don't have any permissions by default. You must grant them explicit permission to perform specific actions. For more information, see Access Control Using AWS Identity and Access Management (IAM).

The UploadMultipartPartRequest type exposes the following members
Constructors
| Name | Description | |
|---|---|---|
|
UploadMultipartPartRequest() |
Empty constructor used to set properties independently even when a simple constructor is available |
|
|
UploadMultipartPartRequest(string, string, string, string, Stream) |
Instantiates UploadMultipartPartRequest with the parameterized properties |
|

Properties
| Name | Type | Description | |
|---|---|---|---|
|
|
AccountId | System.String |
Gets and sets the property AccountId.
The |
|
|
Body | System.IO.Stream |
Gets and sets the property Body. The data to upload. |
|
|
Checksum | System.String |
Gets and sets the property Checksum. The SHA256 tree hash of the data being uploaded. |
|
|
Range | System.String |
Gets and sets the property Range. Identifies the range of bytes in the assembled archive that will be uploaded in this part. Amazon S3 Glacier uses this information to assemble the archive in the proper sequence. The format of this header follows RFC 2616. An example header is Content-Range:bytes 0-4194303/*. |
|
|
StreamTransferProgress | System.EventHandler<Amazon.Runtime.StreamTransferProgressArgs> |
Attach a callback that will be called as data is being sent to the AWS Service. |
|
|
UploadId | System.String |
Gets and sets the property UploadId. The upload ID of the multipart upload. |
|
|
VaultName | System.String |
Gets and sets the property VaultName. The name of the vault. |
Examples
The example uploads the first 1 MiB (1024 x 1024 bytes) part of an archive.
To upload the first part of an archive
var client = new AmazonGlacierClient();
var response = client.UploadMultipartPart(new UploadMultipartPartRequest
{
AccountId = "-",
Body = new MemoryStream(part1),
Checksum = "c06f7cd4baacb087002a99a5f48bf953",
Range = "bytes 0-1048575/*",
UploadId = "19gaRezEXAMPLES6Ry5YYdqthHOC_kGRCT03L9yetr220UmPtBYKk-OssZtLqyFu7sY1_lR7vgFuJV6NtcV5zpsJ",
VaultName = "examplevault"
});
string checksum = response.Checksum;
