Hi Alexis, If you create OutputTag with the constructor `OutputTag(String id)`, you need to make it anonymous for Flink to analyze the type information. But if you use the constructor `OutputTag(String id, TypeInformation<T> typeInfo)`, you need not make it anonymous as you have provided the type information.
The second constructor is introduced after the document and the first constructor, and I think the document might have been outdated and not match with OutputTag's current behavior. A ticket and PR could be added to fix the document. What do you think?
