> Currently Dynamic snitch looks at the latency for figuring out which node will be better serving the requests, this works great but there is a part of the traffic sent to collect this data... There is also a window when Snitch doesn't know about some major event which are going to happen on the node (Node which is going to receive the data request).
> It would be great if we can send some sort hints to the Snitch so they can score based on known events causing higher latencies.
