Can you give a more specific example of what kind of hierarchical data you want to serialize? (eg the output of a groupby operation in pandas typically is still a dataframe that can be converted to pyarrow and serialized).
In general, for hierarchical data we have the nested data types (eg struct type when you nest "multiple columns in a single column").
