Hi Mura, The short answer is: yes, it is possible. Naively, to expose such a function something may need to be added in cython. I am learning more about how to add new compute functions, so I am not sure yet if functions in the function registry are automatically exposed to other languages (e.g. R, python, etc.). When I find out more about how this is done, I can follow up if this is still unanswered.
There are examples of functions that you can call directly without using "CallFunction;" for example, arrow::compute::Add. The second code sample on [1] should show how this is done.
