Hi [~johnmu], 

Seems like the PR is stale and would need major revision and rebasing. I think 
it can be closed. 
Before we make a new attempt to fix this issue, I'd suggest to first check with 
[~aljoscha] who is more familiar with the DataStream API.

Best, Fabian

>                 URL: https://issues.apache.org/jira/browse/FLINK-2184
>             Project: Flink
>          Issue Type: Improvement
>          Components: Scala API, Streaming
>            Reporter: Gábor Hermann
>            Priority: Minor
> In the streaming Scala API there is no method
> {{maxBy(int positionToMaxBy, boolean first)}}
> nor
> {{minBy(int positionToMinBy, boolean first)}}
> like in the Java API, where _first_ set to {{true}} indicates that the latest 
> found element will return.
> These methods should be added to the Scala API too, in order to be consistent.
