Stephan Ewen commented on FLINK-7246:
-------------------------------------
Have a look here, please to see the impact on latency parameters:
https://ci.apache.org/projects/flink/flink-docs-master/dev/datastream_api.html#controlling-latency
We are currently changing this so that this parameter is not needed and you
always get lower latency.

> Key: FLINK-7246
> URL: https://issues.apache.org/jira/browse/FLINK-7246
> Project: Flink
> Issue Type: Bug
> Components: DataStream API, Metrics
> Affects Versions: 1.2.1
> Environment: Local
> Reporter: yinhua.dai
>
> I was running flink 1.2.1, and I have set metrics reporter to JMX to check
> latency of my job.
> But the result is that the latency I observerd is over 100ms even there is no
> processing in my job.
> And then I ran the example SocketWordCount streaming job, and again I saw the
> latency is over 100ms, I am wondering if there is something misconfiguration
> or problems.
> I was using start-local.bat and flink run to start up the job, all with
> default configs.
> Thank you in advance.
