>                 Key: FLINK-33187
>                 URL: https://issues.apache.org/jira/browse/FLINK-33187
>             Project: Flink
>          Issue Type: Improvement
>          Components: Autoscaler
>    Affects Versions: 1.17.1
>            Reporter: Clara Xiong
>            Priority: Major
>
> Problem:
> Some events are sent to Kafka repeatedly such as ScalingReport when 
> autoscaling is not enable,  which consists 99% of all Kafka events in our 
> prod env. This wastes Kafka resources and cause performance  downstream.
> Proposal:
> Suppress duplicate event within an interval defined by a new operator config 
> "scaling.report.interval" in second, defaulted to 1800.
