In this operation, you provide part data // in your request. However, you have an option to specify your existing Amazon S3 // object as a data source for the part you are uploading. To upload a part from an // existing object, you use the UploadPartCopy (https://docs.aws.amazon.com/AmazonS3/latest/API/API_UploadPartCopy.html) // operation. You must initiate a multipart upload (see CreateMultipartUpload (https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateMultipartUpload.html) // ) before you can upload any part. In response to your initiate request, Amazon // S3 returns an upload ID, a unique identifier, that you must include in your // upload part request. Part numbers can be any number from 1 to 10,000, inclusive. // A part number uniquely identifies a part and also defines its position within // the object being created. If you upload a new part using the same part number // that was used with a previous part, the previously uploaded part is overwritten. // For information about maximum and minimum part sizes and other multipart upload // specifications, see Multipart upload limits (https://docs.aws.amazon.com/AmazonS3/latest/userguide/qfacts.html) // in the Amazon S3 User Guide. To ensure that data is not corrupted when // traversing the network, specify the Content-MD5 header in the upload part // request. Amazon S3 checks the part data against the provided MD5 value. If they // do not match, Amazon S3 returns an error. If the upload request is signed with // Signature Version 4, then Amazon Web Services S3 uses the x-amz-content-sha256 // header as a checksum instead of Content-MD5 . For more information see // Authenticating Requests: Using the Authorization Header (Amazon Web Services // Signature Version 4) (https://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-auth-using-authorization-header.html) // . Note: After you initiate multipart upload and upload one or more parts, you // must either complete or abort multipart upload in order to stop getting charged // for storage of the uploaded parts. Only after you either complete or abort // multipart upload, Amazon S3 frees up the parts storage and stops charging you // for the parts storage. For more information on multipart uploads, go to // Multipart Upload Overview (https://docs.aws.amazon.com/AmazonS3/latest/dev/mpuoverview.html) // in the Amazon S3 User Guide . For information on the permissions required to use // the multipart upload API, go to Multipart Upload and Permissions (https://docs.aws.amazon.com/AmazonS3/latest/dev/mpuAndPermissions.html) // in the Amazon S3 User Guide. Server-side encryption is for data encryption at // rest. Amazon S3 encrypts your data as it writes it to disks in its data centers // and decrypts it when you access it. You have three mutually exclusive options to // protect data using server-side encryption in Amazon S3, depending on how you // choose to manage the encryption keys. Specifically, the encryption key options // are Amazon S3 managed keys (SSE-S3), Amazon Web Services KMS keys (SSE-KMS), and // Customer-Provided Keys (SSE-C). Amazon S3 encrypts data with server-side // encryption using Amazon S3 managed keys (SSE-S3) by default. You can optionally // tell Amazon S3 to encrypt data at rest using server-side encryption with other // key options. The option you use depends on whether you want to use KMS keys // (SSE-KMS) or provide your own encryption key (SSE-C). If you choose to provide // your own encryption key, the request headers you provide in the request must // match the headers you used in the request to initiate the upload by using // CreateMultipartUpload (https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateMultipartUpload.html) // . For more information, go to Using Server-Side Encryption (https://docs.aws.amazon.com/AmazonS3/latest/dev/UsingServerSideEncryption.html) // in the Amazon S3 User Guide. Server-side encryption is supported by the S3 // Multipart Upload actions. Unless you are using a customer-provided encryption // key (SSE-C), you don't need to specify the encryption parameters in each // UploadPart request. Instead, you only need to specify the server-side encryption // parameters in the initial Initiate Multipart request. For more information, see // CreateMultipartUpload (https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateMultipartUpload.html) // . If you requested server-side encryption using a customer-provided encryption // key (SSE-C) in your initiate multipart upload request, you must provide // identical encryption information in each part upload using 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 // // UploadPart has the following special errors: // - Code: NoSuchUpload // - Cause: The specified multipart upload does not exist.
