On latency in event processing network

Packing, on my way to a family vacation in Anatalya, Turkey.

Following an interesting discussion yesterday about performance metrics -- it turns out that definition of latency in event processing network is quite tricky. The reason is that an event can move in multiple paths over the network, in some it is filterred out, in some it just getting into internal state of agent since it does not complete a pattern, and in some it may complete a pattern and trigger reaction, thus there are various ways to define the metrics here. This is important since optimization has to take into account the goal function - what is being optimized. More discussion on this area -- after I'll return. I'll be out of touch for a week.
