This operation uploads a part in a multipart upload.
In this operation you provide part data in your request. However, you have an option to specify your existing Amazon S3 object as data source for the part your are uploading. To upload a part from an existing object you use the Upload Part (Copy) operation. For more information, see Upload Part - Copy.
You must initiate a multipart upload (see Initiate Multipart Upload) 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. Each part must be at least 5 MB in size, except the last part. There is no size limit on the last part of your multipart upload.
To ensure that data is not corrupted when traversing the network, specify the
