PyArrow support

[pyssling]

I know there have been previous discussions on columns stores in pytables. I was wondering if anyone has looked into storing pyarrow tables? I think this could be very useful as a complement to the current row oriented tables.

I see pandas is looking at moving to pyarrow for internal representation.

Just wanted to open this discussion, thanks!

Thanks @pyssling it is indeed a very interesting topic and it would be a great enhancement for pytables.

Just for completeness, #233, "ENH: column-wise tables", is a related ticked, and the related proposal in the wiki: Proposal for implementing column-wise tables in PyTables
