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
request, but has not yet been completed or aborted.
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.
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
IsTruncated element with the value of
NextKeyMarker element, and a
To list the remaining multipart uploads, you need to make subsequent
requests. In these requests, include two query parameters:
upload-id-marker. Set the value of
key-marker to the
NextKeyMarker value from the previous response. Similarly, set the value
upload-id-marker to the
NextUploadIdMarker value from
the previous response.
Directory buckets - The
upload-id-marker element and the
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
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
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
General purpose bucket - In the
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

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.
public virtual Task<ListMultipartUploadsResponse> ListMultipartUploadsAsync( String bucketName, CancellationToken cancellationToken )
The name of the bucket to which the multipart upload was initiated. Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format Bucket_name.s3express-az_id.region.amazonaws.com. Path-style requests are not supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must follow the format bucket_base_name--az-id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az2--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide. Access points - When you use this action with an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, 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 action with an access point through the Amazon Web Services 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 S3 User Guide. Access points and Object Lambda access points are not supported by directory buckets. S3 on Outposts - When you use this action 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 you use this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts? in the Amazon S3 User Guide.
A cancellation token that can be used by other objects or threads to receive notice of cancellation.
