Description: The ‘Part Number’ in the context of multipart uploads refers to a unique identifier assigned to each part of an object that is uploaded using the multipart upload method. This method allows a large file to be divided into smaller parts, making its upload and management easier. Each part can be uploaded independently, meaning that if a part fails during upload, only that specific part needs to be re-uploaded instead of the entire file. The ‘Part Number’ is crucial for maintaining the correct order of the parts when assembling the final object in storage. This identifier is an integer that starts at 1 and can go up to 10,000, allowing for great flexibility in uploading large files. The ability to upload parts in parallel also improves efficiency and reduces the total upload time. In summary, the ‘Part Number’ is an essential component in the multipart upload process, ensuring that each data fragment is managed effectively and combined correctly into the final object.
