> Scala DataSet API ignores ResultTypeQueryable interface
> -------------------------------------------------------
>
> Key: FLINK-7142
> URL: https://issues.apache.org/jira/browse/FLINK-7142
> Project: Flink
> Issue Type: Bug
> Components: API / DataSet, API / Scala
> Affects Versions: 1.3.1, 1.4.0
> Reporter: Fabian Hueske
> Priority: Minor
> Labels: auto-deprioritized-major, stale-minor
>
> The {{ResultTypeQueryable}} is used to specify the return type of
> user-defined functions. The Scala DataSet API ignores this interface. The
> only way to override the inferred type information is to use implicit values.
> However, the {{ResultTypeQueryable}} interface has the nice property that the
> return type is defined in the actual function, whereas implicit types are
> defined in the program, i.e., outside of the function.
> IMO, the Scala DataSet API should also support the {{ResultTypeQueryable}}
> interface.
> What do you think [~aljoscha], [~till.rohrmann]?
> Was it a conscious decision to only support implicit type definitions?
