> If it does not makes sense to invoke `select_k_unstable` without providing a `k` and `sort_keys`, then also make these parameters mandatory in the [`SelectKOptions`](https://github.com/apache/arrow/blob/master/cpp/src/arrow/compute/api_vector.h#L126). > > Although, client code can still provide an invalid value of `k` and an empty vector to `sort_keys`, it expresses the desired intent. You are right, however there is a requirement to have a default constructor enabled to implement copy here: https://github.com/apache/arrow/blob/4fde2068051f43e1639777f289b5ab83cb6bf6f9/cpp/src/arrow/compute/function_internal.h#L634 I think this was a a design decision to implement a general copy method with the registered properties. -- This is an automated message from the Apache Git Service.
