We already have the switch: {{enableObjectReuse()}}

>                 Key: FLINK-2917
>                 URL: https://issues.apache.org/jira/browse/FLINK-2917
>             Project: Flink
>          Issue Type: Improvement
>          Components: Streaming
>            Reporter: Gyula Fora
>            Priority: Blocker
> Currently chained streaming operators copy their output before invoking the process method
of the chained output task.
> The community has agreed that this might be too big of a price for the immutable semantics
and the default behaviour should be changed to not copy.
> I suggest to have an api level switch for the Operators to enable copying.
