[jira] [Created] (FLINK-1188) Streaming aggregations on array types

Márton Balassi created FLINK-1188:
-------------------------------------

             Summary: Streaming aggregations on array types
                 Key: FLINK-1188
                 URL: https://issues.apache.org/jira/browse/FLINK-1188
             Project: Flink
          Issue Type: Improvement
          Components: Streaming
    Affects Versions: 0.8-incubating
            Reporter: Márton Balassi
            Assignee: Gyula Fora


Currently aggregations work on fields of tuples, the goal of the issue is to extend this functionality to positions of arrays. One solution is to use an implementation of the KeySelector interface, however it would be a nice enhancement to have an API option for arrays, e.g. DataStream<int[]> intSream.min(0).
