This operation lists in-progress multipart uploads in a bucket. An in-progress multipart
upload is a multipart upload that has been initiated by the Directory buckets - If multipart uploads in a directory bucket are in progress,
you can't delete the bucket until all the in-progress multipart uploads are aborted
or completed.
CreateMultipartUpload
request, but has not yet been completed or aborted.
The ListMultipartUploads operation returns a maximum of 1,000 multipart uploads
in the response. The limit of 1,000 multipart uploads is also the default value. You
can further limit the number of uploads in a response by specifying the max-uploads
request parameter. If there are more than 1,000 multipart uploads that satisfy your
ListMultipartUploads request, the response returns an IsTruncated element
with the value of true, a NextKeyMarker element, and a NextUploadIdMarker
element. To list the remaining multipart uploads, you need to make subsequent ListMultipartUploads
requests. In these requests, include two query parameters: key-marker and upload-id-marker.
Set the value of key-marker to the NextKeyMarker value from the previous
response. Similarly, set the value of upload-id-marker to the NextUploadIdMarker
value from the previous response.
Directory buckets - The upload-id-marker element and the NextUploadIdMarker
element aren't supported by directory buckets. To list the additional multipart uploads,
you only need to set the value of key-marker to the NextKeyMarker value
from the previous response.
For more information about multipart uploads, see Uploading Objects Using Multipart Upload in the Amazon S3 User Guide.
Directory buckets - For directory buckets, you must make requests for this
API operation to the Zonal endpoint. These endpoints support virtual-hosted-style
requests in the format https://bucket_name.s3express-az_id.region.amazonaws.com/key-name. Path-style requests are not supported. For more information, see Regional
and Zonal endpoints in the Amazon S3 User Guide.
General purpose bucket permissions - For information about permissions required to use the multipart upload API, see Multipart Upload and Permissions in the Amazon S3 User Guide.
Directory bucket permissions - To grant access to this API operation on a
directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically,
you grant the s3express:CreateSession permission to the directory bucket in
a bucket policy or an IAM identity-based policy. Then, you make the CreateSession
API call on the bucket to obtain a session token. With the session token in your request
header, you can make API requests to this operation. After the session token expires,
you make another CreateSession API call to generate a new session token for
use. Amazon Web Services CLI or SDKs create session and refresh the session token
automatically to avoid service interruptions when a session expires. For more information
about authorization, see CreateSession.
General purpose bucket - In the ListMultipartUploads response, the
multipart uploads are sorted based on two criteria:
Key-based sorting - Multipart uploads are initially sorted in ascending order based on their object keys.
Time-based sorting - For uploads that share the same object key, they are further sorted in ascending order based on the upload initiation time. Among uploads with the same key, the one that was initiated first will appear before the ones that were initiated later.
Directory bucket - In the ListMultipartUploads response, the multipart
uploads aren't sorted lexicographically based on the object keys.
Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginListMultipartUploads and EndListMultipartUploads.
