Because I want to :) Well, I have a memory mapped file open in Python, and I want to wrap that in my own Python File-like object that does some checks before every read (it's a caching mechanism) and pass that File like object down to arrow (which performs badly now). So I have a buffer/memoryview (the memory mapped file) that I want to expose to Arrow via a File API without a memory copy. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
