Rok Mihevc commented on ARROW-1614:
-----------------------------------

As proposed by [~jorisvandenbossche] I've made a draft PR ( 
[https://github.com/apache/arrow/pull/8510.]) with python logic prototype. It 
was heavily inspired by [~bryanc]'s text-extensions-for-pandas. Once we agree 
on the design we can rewrite it to c++.

As this is for the case where all tensors in the array are of the same shape I 
propose we store the data in a single Tensor. Is there a good reason not to do 
that?

I assume we should support non-contiguous tensors. I'll add that.

Any comments at this point?
