    Parameters
    ----------
    integer_compacting : bool
        enable/disable compacting of integer channels on append. This has the
        potential to greatly reduce file size, but append speed is slower and
        further loading of the resulting file will also be slower.
    split_data_blocks : bool
        enable/disable splitting of large data blocks using data lists for
        mdf version 4
    split_treshold : int
        size hint of splitted data blocks, default 2MB; if the initial size is
        smaller then no data list is used. The actual split size depends on
        the data groups' records size
    overwrite : bool
        default option for save method's overwrite argument
