hi Dan
See
https://lists.apache.org/thread.html/r0be397a5f901b9dc8787a7dbcb0a34c9ed60ad07ff1e3f064d418a98%40%3Cdev.arrow.apache.org%3E.
There is an experimental implementation in C++ which is being used for
"Feather V2"
The Arrow specification does include a "file" format -- this is
exactly what "Feather V2" is using
