Description

In the Event Flow Debugger, it is difficult to see exactly how events are merged and where latency is coming from. While the event temporal properties are shown, it doesn't show you where the event "passed" through the stream operator. This can make it difficult to understand where to tweak and optimize to minimize latencey

Tracking system time is not only costly in terms of performance impact but also imprecise for certain query constructs. We have some DV counters which approximate these information:

QueryTotalConsumedEventLatency
QueryTotalProducedEventLatency
QueryTotalOutgoingEventLatency
