Ah, I misread the description, apologies. It's an interesting idea. I don't see an easy solution right now especially since the udf's are held in a singleton once called (see https://github.com/apache/arrow-datafusion/blob/d8d521ac8b90002fa0ba1f91456051a9775ae193/datafusion/functions/src/macros.rs#L66) so any memory savings from not using the udf would evaporate after the first use. I think it may be possible with a change to the make_udf_function to remove the singleton code however I'm not sure of the wisdom of that. -- This is an automated message from the Apache Git Service.
