Xu Mingmin updated BEAM-1797:
-----------------------------
    Description: 
In https://beam.apache.org/documentation/programming-guide/#transforms-sideio, the chapter
{{Using GroupByKey}} describes how to apply a GroupBy on one single {{PCollection}} with {{GroupByKey}}.

Would like to change the subject title as
