I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Minor but is unassigned and neither itself nor its Sub-Tasks have been updated
for 180 days. I have gone ahead and marked it "stale-minor". If this ticket is
still Minor, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.

> Key: FLINK-5094
> URL: https://issues.apache.org/jira/browse/FLINK-5094
> Project: Flink
> Issue Type: Improvement
> Components: API / DataStream
> Affects Versions: 1.1.3, 1.2.0
> Reporter: Fabian Hueske
> Priority: Minor
> Labels: auto-deprioritized-major, stale-minor
>
> Support {{RichReduceFunction}} and {{RichFoldFunction}} as incremental window
> aggregation functions in order to initialize the functions via {{open()}}.
> The main problem is that we do not want to provide the full power of
> {{RichFunction}} for incremental aggregation functions, such as defining own
> operator state. This could be achieve by providing some kind of
> {{RestrictedRuntimeContext}}.
