> https://beam.apache.org/documentation/programming-guide/#additional-outputs
> The current document should clarify that while using sideOutput, the TupleTag must be declared as anonymous class.
> "Using side outputs brings a specific rule regarding to the coders. The TupleTag must be declared as an anonymous class (suffixed with {} to the constructor call). Otherwise coder's inference would be compromised."
