   Exactly fall into the same issue here. I think the cpp doc mentioned by @jrecuerda above is a little confusing because the "Invoking functions" section teaches us the way to use CallFunction and "Grouped Aggregations" section lists out the names and input args. Then a natural way for me to do group by is arrow::compute::CallFunction but it does not work
