> Naming UDF. The feedback of committers giving talks about Flink some time
ago was that the name "UDF" was sometimes confusing. @rmetzger, can you confirm
this? We might take this into account and rename the UdfAnalysisMode to
something else, for example just CodeAnalysisMode.
That's right. People associate UDFs with SQL databases that allow to pass
in custom functions (which is right, but they start thinking Flink is a SQL
database).
In this case, its not super critical because its internal code.
