------------------------------------
Summary: Change Latency Marker to work with "scheduleAtFixedDelay"
instead of "scheduleAtFixedRate"
Key: FLINK-17816
URL: https://issues.apache.org/jira/browse/FLINK-17816
Project: Flink
Issue Type: Bug
Components: Runtime / Task
Reporter: Stephan Ewen
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.
