Hi everyone, I would like to start discussion about how to support Python UDF in SQL Function DDL.
The SQL Function DDL(FLIP-79[1]) is a great feature which was introduced in the release of 1.10.0. However, it currently only supports creating Java/Scala UDF in the SQL Function DDL. Although FLIP-79 has already proposed a statement about how to create Python UDF in the SQL Function DDL, it’s still not supported yet. We want to introduce the support of Python UDF in the SQL Function DDL to fill this gap. It provides another way of using Python UDF and could extend Python UDF to users of Java/Scala Table API, SQL client, etc. Here is the design doc: https://cwiki.apache.org/confluence/display/FLINK/FLIP-106%3A+Support+Python+UDF+in+SQL+Function+DDL Looking forward to your feedback! Best, Wei [1] https://cwiki.apache.org/confluence/display/FLINK/FLIP-79+Flink+Function+DDL+Support
