   Sorry for the delay but here is an update on a few things.
   
   We are working on documenting the C++ exec plans API here: https://github.com/apache/arrow/pull/12033
   
   The exec plans API for 6.0.1 (and 7.0.0) is still pretty rough around the edges.  I've jotted down some potential improvements here: https://issues.apache.org/jira/browse/ARROW-15257
   
   As mentioned earlier, a simpler API for aggregations is being added to pyarrow as part of 7.0.0 which will be releasing fairly soon (within the next month).
   
   As promised I have sketched up a minimal (though not very simple) C++ example of averaging a table grouped by a column: https://gist.github.com/westonpace/e555a3b1c269c31de7176d34f47a2fb0
