> Key: FLINK-20571
> URL: https://issues.apache.org/jira/browse/FLINK-20571
> Project: Flink
> Issue Type: Improvement
> Components: API / DataStream
> Reporter: zlzhang0122
> Priority: Major
> Labels: auto-deprioritized-major
>
> Now, flink has provided latency metrics to monitor the latency, but this
> function mainly used in debugging contexts rather than in production contexts
> because of throughput effect. If we provider an api that can dynamic
> open/close this function, then we can monitor the online data latency and
> find out the performance bottleneck in time without restart the job, which
> maybe helpful for online debug.Â
