Subject Re: Enforce an operation to run in an exact host in flink
Date Mon, 21 Nov 2016 16:58:56 GMT
If I'm not mistaken Flink already has metrics that report latencies. These
are not 100% correct because they machine one which an element originates
is not necessarily the machine on which we measure the latency.

I'm afraid that that's the best we can do right now, however. Other than
running your pipeline on only one machine.
