Gyula Fora created FLINK-1121:
---------------------------------

             Summary: Add minBy and maxBy operators to the streaming api
                 Key: FLINK-1121
                 URL: https://issues.apache.org/jira/browse/FLINK-1121
             Project: Flink
          Issue Type: Improvement
          Components: Streaming
    Affects Versions: 0.7-incubating
            Reporter: Gyula Fora
            Assignee: Gyula Fora
            Priority: Minor


The minBy and maxBy operators are missing from the streaming api, so a similar operator as in batch should be added.

The operator would always return the current min/max element in the datastream so far. An optional parameter should be added to choose to return the first or last min/max value occurance.
