Hi all, I would like to compute the latency of my topology (time spend by a message form the spout to the end of my topology).
Until now, I enable the acking (1 acker per worker) and I get the result in storm UI. But today I discover that disable the acking seep up my topology by a factor of 10 (unit: tupes per second). I also try to compute this value by my self by seting a time stamp in the tuples in the spout. Then I compute the lantency at the end of the topology. As the clocks of my machies are not synchronized, I get very strange results. So my question is how to compute the latency with a weak algorithm/tool. Thanks for your help. Regads, D.
