Thank you!

I don't think there's any benefit in keeping RecordBatch abstract.
Making it concrete would probably reduce overhead slightly as well.
People who need abstract tabular data capabilities can still implement
Table (though I wonder if that ability has ever been used productively).

Thanks for looking into this, Micah.
One convention I'd like to append: we mostly avoid convenience typedefs,
but an
exception is the common case of `vector>`, for
which we
allow and encourage the use of `{class name}Vector` typedefs. (Conversely,
nothing
should be named /^\w+Vector$/ which isn't
(Apologies if this is a double send)
I'll open a PR on this soon. To update the dev guide.
Given this standard there are few accessor methods that I think we should
either convert or create a new accessor that does the correct thing with
respect to return type. Given how core these methods are I
Agreed. We should probably document this in the C++ developer docs.

Hi Micah,
That's roughly my mental model as well.
However, for 4) I would say that return a const ref to shared_ptr if
preferable because the caller will often need the ownership (especially
with Array, ArrayData, DataType, etc.).

I'm not sure how consistent we are with how shared_ptr is used as a
parameter to methods and as a return type. In reviewing and writing code
I've been using these guidelines for myself and I was wondering if they
align with others:
1. If a copy of a shared_ptr is not intended to be made by the m
