> In this JIRA, we will enhance the run-time code generation component, in the
> following ways:
> 1. Allow generate the run-time code for function whose parameter is
> FieldReader. A parameter FieldReader could match an argument of Repeated
> List, Repeated Map, or an element in Repeated List/map, or any nested complex
> type.
> 2. In addition, FieldReader will also match any singular value, such as int,
> float4, varchar.
> With this support enabled, one could implement a function with parameter
> FieldReader to match any simple or complex nested type.
> As an example of how to leverage this new code generation logic, we add a new
> function "convert_toJson", which will convert any simple or complex type into
> a string in json format.
> @Param FieldReader input;
> @Output VarBinaryHolder out;
