Hi!
It seems that if a DataFrame contains both numeric and object columns,
the whole DataFrame is pickled and not that only object columns are
pickled? Is this right? Are there any plans to improve this?

Hi!
It seems numpy's matrix is not supported in recent versions of pyarrow:
https://issues.apache.org/jira/browse/ARROW-3399
Any ideas why this would be happening?

Hi!
I do not know where to start looking into this? Not sure if I have
enough knowledge about arrow to be able to make a PR.

An interesting fact is that this worked in older versions of numpy,
but stopped in numpy 1.15.2. It works with numpy 1.14.3. So it is them
changing something.

Hi!
I agree. This is in fact all information which is already there. :-)

attempt at registering
custom serialization:

It looks like custom serialization is not called.

serialization for
ndarray but the existing ndarray serialization would work, casting it
into a proper subclass.

Hi!
The website seems to say that there is already a pyarrow 0.9.0
package, but it does not seem to be there yet:
https://arrow.apache.org/install/#python-wheels-on-pypi-unofficial
https://pypi.python.org/pypi/pyarrow
BTW, why are Python packages unofficial?

Hi!
Oh, no worries. Thanks for working on this. I just thought that
because the website went up it is ready and thought that there is some
bug there. I understand it takes time to do a release, properly.
