UploadPart

Retains part of the object.

The user independently numbers the parts of the object and transfers the numbers to ColdStack. The number uniquely identifies the part and determines its order in the overall sequence. A number is an integer between 1 and 10,000, inclusive.

If multiple chunks with the same number are loaded, ColdStack retains the last one that arrived.

Each part, except the last, must be at least 5MB in size.
