This sounds interesting. Can you give an example when this might be useful?

> Key: FLINK-6989
> URL: https://issues.apache.org/jira/browse/FLINK-6989
> Project: Flink
> Issue Type: Sub-task
> Components: Gelly
> Affects Versions: 1.4.0
> Reporter: Greg Hogan
> Assignee: Greg Hogan
> Fix For: 1.4.0
>
>
> The current organization of the Gelly examples retains full flexibility by
> handling the Graph input to the algorithm Driver and having the Driver
> overload interfaces for the various output types. The outputs must be made
> independent in order to support Transforms which are applied between the
> Driver and Output (and also between the Input and Driver).
