Hi! While working with grouping and windowing I encountered a strange behavior. I'm doing: > dataStream.groupBy(KeySelector).window(Time.of(x, > TimeUnit.SECONDS)).mapWindow(toString).flatten()
When I run the program containing this snippet it initially outputs data at a rate around 150 events per sec. (That is roughly the input rate for the program). After about 10-30 minutes the rate drops down below 5 events per sec. This leads to event delivery offsets getting bigger and bigger ... Any explanation for this? I know you are reworking the streaming API. But it would be useful to know, why this happens ... Cheers. Rico.
