I proposed an API here:
https://github.com/apache/arrow/pull/8052
It is not much different from what Wes proposed earlier in the thread,
except in error reporting. Comments welcome (here or on the PR).

Antoine.

I opened https://issues.apache.org/jira/browse/ARROW-9761 about adding
a preliminary C++ (and Python) implementation to help stir the pot. My
understanding is that DuckDB is working on using the C interface right
now [1] and the absence of an iterator interface makes such
integration require more
I think this unlocks a bunch of use cases. I think people are generally
using Arrow in simpler, non-streaming ways right now and thus the quiet.
Producing an iterator pattern is logical as you move to streams of smaller
chunks (common in distributed and multi-tenant systems).

I'm still in need of it. I'd be interested in developing a solution
that can be used in some database APIs, e.g. using it for the result
interface for an embedded SQL database like SQLite or DuckDB would be
an interesting motivating use case.
One approach would be to create something unofficial
From the absence of response, it would seem there isn't much interest
in this. Please speak up if you think this would be useful to you.

Antoine.

Any opinions about this? It seems the next steps would be a concrete
API proposal and perhaps a reference implementation thereof.

In ARROW-8301 [1] and elsewhere we've been discussing how to
communicate what amounts to a sequence of arrays or a sequence of
RecordBatch objects using the C data interface.
Example use cases:
* Returning a sequence of record / row batches from a database driver
* Sending a C++
