I think based on the src file dataset.py the compression False is not possible

        self,
        show_progress=True,

        output_url=None,

        chunk_size=None,

        retries=3,
    ):

        :param output_url: Target storage for the compressed dataset (default: file server)

        :param chunk_size: Artifact chunk size (MB) for the compressed dataset,
            if not provided (None) use the default chunk size (512mb).
            If -1 is provided, use a single zip artifact for the entire dataset change-set (old behaviour)
        :param max_workers: Numbers of threads to be spawned when zipping and uploading the files.
            If None (default) it will be set to:

          - number of logical cores: otherwise
        :param int retries: Number of retries before failing to upload each zip. If 0, the upload is not retried.

        :raise: If the upload failed (i.e. at least one zip failed to upload), raise a `ValueError`

Hi @<1698868530394435584:profile|QuizzicalFlamingo74> , Try compression=False

@<1706116294329241600:profile|MinuteMouse44> unfortunately no, I created my own upload method with python Django and passed the S3 directories to the clearML dataset to track of datasets.

@<1698868530394435584:profile|QuizzicalFlamingo74> did u find solution?)

Which is not an ideal solution but for now it's working.
