Thanks! Apache Arrow may also be worth a look:

> Apache Arrow is a cross-language development platform for in-memory data.
It specifies a standardized language-independent columnar memory format for
flat and hierarchical data, organized for efficient analytic operations on
modern hardware. It also provides computational libraries and zero-copy
streaming messaging and interprocess communication.

> The Arrow Python bindings have first-class integration with NumPy,
pandas, and built-in Python objects

Pickle supports arbitrary Python objects without any schema definition
(other than that what's defined in the object's __reduce__()
and __reduce_ex__())
