Wes McKinney commented on ARROW-12888:
--------------------------------------

I'm still not clear on what the function should return. 

It could be one of:

* The size of the Table on the wire in the IPC stream format
* The sum of the {{Buffer::size}} for all {{Buffer}} objects in the Table's 
columns 
* The sum of all Buffer sizes along with the footprint of all of the 
constituent C++ structures

I suspect it is #1 or #2
