Oh, `scalar_functions` is good to use for that. We can get particular `ScalarUDF` from it without matching scalar udf name outside DataFusion. Although it is still not creating the `ScalarUDF` on demand. As I described in the description, for queries which don't use most of these scalar udfs, it looks unnecessary to create and hold these `ScalarUDF`s in the registry. I think a better approach should be to create `ScalarUDF` once it is really needed. This is how Spark handles function registry. -- This is an automated message from the Apache Git Service.
