Subject Metrics for number of "open windows"?
Date Tue, 19 Feb 2019 20:14:18 GMT
Hello,

I’m trying to track the number of currently-in-state windows in a keyed, windowed stream
(stream.keyBy(…).window(…).trigger(…).process(…)) using Flink metrics. Are there any
built in? Or any good approaches for collecting this data?

Thanks,

Andrew
