  • Add maxObjectSize constant calculated from maxPartSize * maxPartsCount
  • Update size validation to allow objects up to ~48.83TiB
  • Add configurable PartSize to CopyDestOptions for compose operations
  • Update partsRequired() and calculateEvenSplits() to accept part size
  • Keep 5TiB default for unknown size (-1) to limit memory usage
  • Update documentation to reflect new limits
