----------------------------------------

             Summary: Allow more aggregations on KeyValueGroupedDataset
                 Key: SPARK-18299
                 URL: https://issues.apache.org/jira/browse/SPARK-18299
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.0.1
            Reporter: Matthias Niehoff


The number of possible aggregations on a KeyValueGroupedDataset created by groupByKey is limited to 4, as there are only methods with a maximum of 4 parameters.

This value should be increased or - even better - made be completely unlimited.
