> Key: FLINK-14658
> URL: https://issues.apache.org/jira/browse/FLINK-14658
> Project: Flink
> Issue Type: Sub-task
> Components: API / DataStream
> Reporter: Stephan Ewen
> Priority: Major
> Fix For: 2.0-preview
>
>
> The pattern to use {{.map(function).returns(type)}} to override the
> automatically extracted type is flawed and should not be used.
> Instead, each transformation method should be overloaded to have a variant
> that accepts the return type as the second argument, if in case we want to
> override the type extractor.
> See [FLINK-14380] for good example of why the {{.returns(type)}} pattern is
> broken.
