Subject Register a user scope metric in window reduce function
Date Thu, 19 Jan 2017 02:51:47 GMT
Hi team,

Is there any way that I can register a metric in a window reduce function?
As per the flink doc getRuntimecontext is only available in RichFunction
but window operator doesn't allow RichFunction to be chained. Any way to
workaround this?
