I'd like to use HadoopFileSystem to open a file and then a read a block of
data specified by the offset and the length.
I see that for libhdfs driver, arrow supports hdfsPread API. It also
exposes it as ReadAt method of the RandomAccessFile interface. I did not
find don'ta way to access it from Pyt

hi Yevgeni,
Would you like to add a `read_at` method to `pyarrow.NativeFile`? This

Hi Wes,
This approach seems reasonable to me. I'm a little concerned we haven't
validated many use-cases against the approach (but I don't see any obvious

The use cases I'm aware of are mostly coming from proprietary applications.
My idea was for the extension metadata to be as unobtrusive as possible.
The only alternative as I see it would be to have an Extension value in the

Hi Wes,
Like I said I think this approach looks good, I think what I'm looking for
is a little more documentation/examples on how additional types would be
handled. I think Tensor would be a good example, we also had questions
about INET addresses previously, maybe this would be a another good
