Initially I think we should wrap `@ScalarFunction` annotated methods into a `BuiltInScalarFunction implements FunctionDefinition` where all the interfaces are defined to support more complex function signatures. Similar architecture is adopted in many sql-like systems to support UDF/UDAF/UDTF etc. thus I think the design should be sufficient. I will create a separate design doc for the `FunctionDefinition` interface as well as how they will used for - dynamic arg/return type - stateful initialization (for example one of the arguments are literal expression) - overloading and implicit type conversion if no exact arg type is found. -- This is an automated message from the Apache Git Service.
