Jiayi Liao commented on FLINK-17816:
------------------------------------
I guess the change would be simple. We might just need to replace
{{scheduleAtFixedRate}} with {{registerTimer}} in `LatencyMarksEmitter` like
this:

> Change Latency Marker to work with "scheduleAtFixedDelay" instead of
> "scheduleAtFixedRate"

> Issue Type: Bug
> Components: Runtime / Task
> Reporter: Stephan Ewen
> Priority: Major
>
> Latency Markers and other periodic timers are scheduled with
> {{scheduleAtFixedRate}}. That means every X time the callable is called. If
> it blocks (backpressure) is can be called immediately again.
> I would suggest to switch this to {{scheduleAtFixedDelay}} to avoid calling
> for a lot of latency marker injections when there is no way to actually
> execute the injection call.
