      Description

      This function doesn't implement partial aggregation and shuffles all data. A uadf that supports partial aggregation is not covered by this Jira.
      Exmaple:

      @pandas_udf(DoubleType())
      def mean(v)
            return v.mean()
      
      df.groupby('id').apply(mean(df.v1), mean(df.v2))
