Using Apache Arrow

[mrkn]

Apache Arrow provides common representation of in-memory columnar data. I think daru should use this to be interoperable with other platforms such as pandas.

@v0dro How do you think about that?

Works! How can we make this happen? I'm seeing a lot of work in this direction being done by Wes McKenny too. This should be great.

Intriguing. Would this only work with JRuby, or would it be possible to work with MRI too?

Maybe contribute a ruby binding of https://github.com/wesm/feather

There is actually an open issue for that: https://github.com/wesm/feather/issues/282
