source

present_data_size_column(
    df: DataFrame ,
)-> ‘pd.DataFrame’

Expose _data_size as data_size.

Keeping sample counts private lets chunk merge patches of different lengths. Counts are unknown for merged or subdivided chunks and patches trimmed by selection.

Use nullable Int64 when any count is missing, including columns returned untyped by SQL; otherwise use int.
