   > *what do you use serialize for currently?*
   
   I've just got a proof-of-concept arrow serialization framework which can serialize arbitrary Python objects (inheriting from a base class). Unfortunately, after implementing that I found it's not language-agnostic so it's languished as a bit of a curiosity.
   
   I need a language-agnostic serialization format which can serialise a Python `Dict[str, object]` where `object` is itself serializable to a `Dict[str, primitive_type]`. I'm performance sensitive and may need to serialize large arrays/DataFrames (*"primitive"* data-science types). Given that, I hoped `pyarrow` might fit the bill but it doesn't seem suited to serializing heterogeneous mappings?
   
   Currently wondering if `msgpack` might be better suited but interested to hear if this is something on the radar/roadmap for `arrow`?
