I think this should be an `ITCase` since we actually run a complete Flink
job.
> Provide an enhanced KeyedStream implementation to use ForwardPartitioner
> ------------------------------------------------------------------------
>
> Key: FLINK-8571
> URL: https://issues.apache.org/jira/browse/FLINK-8571
> Project: Flink
> Issue Type: Improvement
> Reporter: Nagarjun Guraja
> Assignee: Stefan Richter
> Priority: Major
>
> This enhancement would help in modeling problems with pre partitioned input
> sources(for e.g. Kafka with Keyed topics). This would help in making the job
> graph embarrassingly parallel while leveraging rocksdb state backend and also
> the fine grained recovery semantics.
