> After FLINK-15281 is merged, we are able to introduce functions with the new type inference. We start by enabling scalar functions through the stack.
> This includes the following changes:
> - Introduce a {{UserDefinedFunction.getTypeInference}} method
> - Expose {{TableEnvironment.createTemporarySystemFunction}} and {{TableEnvironment.createTemporaryFunction}}
> - Update FunctionCatalog
> - Update the code generation
