Hi Steve,
Key-value metadata is exposed in both Python and R. See
https://arrow.apache.org/docs/python/generated/pyarrow.Schema.html?highlight=metadata#pyarrow.Schema.metadata
and https://arrow.apache.org/docs/r/articles/arrow.html#r-object-attributes,
respectively.

Is there a way to read/write user-defined metadata in IPC format? As far
as I know, metadata seems to exist for data schema only. It would be very
helpful to expose key-value metadata interface in C++/Python and R APIs.
Best,
Steve
