Flink Jira Bot updated FLINK-11198:
-----------------------------------
Labels: auto-unassigned stale-major (was: auto-unassigned)
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
Major but is unassigned and neither itself nor its Sub-Tasks have been updated
for 30 days. I have gone ahead and added a "stale-major" to the issue". If this
ticket is a Major, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.
> Access to MetricGroup in an AggregateFunction(Non Rich)

> Key: FLINK-11198
> URL: https://issues.apache.org/jira/browse/FLINK-11198
> Project: Flink
> Issue Type: New Feature
> Components: API / DataStream
> Affects Versions: 1.6.2
> Reporter: Chirag Dewan
> Priority: Major
> Labels: auto-unassigned, stale-major
>
> The only way to add custom metrics from UDF is through RuntimeContext. And,
> RuntimeContext is wired in every RichFunction implementation.
> However, for aggregate() in Windowed Stream, we cannot use the Rich version
> of AggregateFunction. As I remotely understand, is done to avoid exposing the
> state in the Aggregate UDF.
> But can we have some minimal context which does not expose state but provide
> metrics, classloader etc.in the UDF?
