// This operation initiates a multipart upload. Amazon S3 Glacier creates a
// multipart upload resource and returns its ID in the response. The multipart
// upload ID is used in subsequent requests to upload parts of an archive (see
// UploadMultipartPart). When you initiate a multipart upload, you specify the part
// size in number of bytes. The part size must be a megabyte (1024 KB) multiplied
// by a power of 2-for example, 1048576 (1 MB), 2097152 (2 MB), 4194304 (4 MB),
// 8388608 (8 MB), and so on. The minimum allowable part size is 1 MB, and the
// maximum is 4 GB. Every part you upload to this resource (see
// UploadMultipartPart), except the last one, must have the same size. The last one
// can be the same size or smaller. For example, suppose you want to upload a 16.2
// MB file. If you initiate the multipart upload with a part size of 4 MB, you will
// upload four parts of 4 MB each and one part of 0.2 MB. You don't need to know
// the size of the archive when you start a multipart upload because Amazon S3
// Glacier does not require you to specify the overall archive size. After you
// complete the multipart upload, Amazon S3 Glacier (Glacier) removes the multipart
// upload resource referenced by the ID. Glacier also removes the multipart upload
// resource if you cancel the multipart upload or it may be removed if there is no
// activity for a period of 24 hours. 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)
// (https://docs.aws.amazon.com/amazonglacier/latest/dev/using-iam-with-amazon-glacier.html).
// For conceptual information and underlying REST API, see Uploading Large Archives
// in Parts (Multipart Upload)
