Perspective uses arrow across the wire but internally uses it's own formats.

Hi Michael,
We are targeting grouped aggregation for 4.0 as part of a general query
engine buildout. We also intend to bring DataFrame functionality into core
Arrow (which would probably include an analog of pandas' pivot_table), but

row or column pivots in Arrow?
I know Pandas does it already some way
