Now we cannot use UDF and UDAF in ballista because ballista cannot know how to serialize and deserialize UDF / UDAF. We are using Trino. Referring to the practice of Trino, we can realize the plug-in of UDF through the way of rust dynamic library. In this way, ballista and datafusion only need to know the plug-in interface of UDF, and they can work without knowing the specific implementation of UDF. -- This is an automated message from the Apache Git Service.
