Hi everyone, I would like to start discussion about how to support Python UDF in SQL Client.
Flink Python UDF(FLIP-58[1]) has already been introduced in the release of 1.10.0 and the support for SQL DDL is introduced in FLIP-106[2]. SQL Client defines UDF via the environment file and has its own CLI implementation to manage dependencies, but neither of which supports Python UDF. We want to introduce the support of Python UDF for SQL Client, including the registration and the dependency management of Python UDF. Here is the design doc: https://cwiki.apache.org/confluence/display/FLINK/FLIP-114%3A+Support+Python+UDF+in+SQL+Client Looking forward to your feedback! Best, Wei [1] https://cwiki.apache.org/confluence/display/FLINK/FLIP-58%3A+Flink+Python+User-Defined+Stateless+Function+for+Table [2] https://cwiki.apache.org/confluence/display/FLINK/FLIP-106%3A+Support+Python+UDF+in+SQL+Function+DDL
