> The current UDF integration (https://issues.apache.org/jira/browse/ARROW-15639) doesn't support multiple kernel registration. It only supports registering a single kernel under a given function name. Enabling multiple kernels to be registered under the same function name is a must for usability and consistency with the existing functions in the function registry.
