-------------------------------------

             Summary: [C++][Docs] Clarify that not all compute functions are invocable via CallFunction
                 Key: ARROW-15269
                 URL: https://issues.apache.org/jira/browse/ARROW-15269
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++, Documentation
            Reporter: Eduardo Ponce
             Fix For: 8.0.0


It has been noted by users that the [Compute Functions documentation ("Invoking functions" section) states that functions are invoked via CallFunction|https://arrow.apache.org/docs/cpp/compute.html#invoking-functions], but there exist functions (specifically ["Grouped aggregations"|#grouped-aggregations-group-by]) that can't be invoked directly via {{CallFunction}}. This is a bit misleading, although this is stated in the description of "Grouped aggregations".

Grouped aggregations are stateful functions and at the moment stateful functions are invocable in such a way.

We should clarify in "Invoking functions" section that not all compute functions are directly invocable via {{CallFunction}}.
