Rok Mihevc commented on ARROW-15571:
------------------------------------
Python maps directly to c++ kernels here and it's less verbose.
Perhaps take a look at
[https://github.com/apache/arrow/blob/master/cpp/src/arrow/compute/kernels/scalar_compare_test.cc#L1228]
and
[https://github.com/apache/arrow/blob/master/cpp/src/arrow/compute/kernels/scalar_arithmetic_test.cc#L932]
to get c++ implementation start.
> [C++] Add min/max/sqrt scalar kernels to execution engine
