That was my first alternative actually :)
That works well for per window metrics. And though it fits perfectly for
smaller windows, it might not be frequent enough for larger window sizes.

Hi Chirag,
I am afraid you are right you cannot access metrics from within
AggregateFunction in WindowedStream. You can though use rich variant of
WindowFunction, which is invoked for every window with the results of
AggregateFunction. Would that be enough for your use case to use
.aggregate(aggregateFunction, windowFunction) and register metrics in the
windowFunction?
Best,
Dawid

Hi,
I am writing a Flink job for aggregating events in a window.
I am trying to use the AggregateFunction implementation for this.
Now, since WindowedStream does not allow a RichAggregateFunction for
aggregation, I cant use the RuntimeContext to get the Metric group.
I dont even see any other way of accessing the Metric Group in a non-rich
function implementation?
Is there any way around here?
Any help appreciated.
Thanks,
Chirag
