Vijay commented on CASSANDRA-3722:
----------------------------------

Hi Brandon, Will it make sense for the remote node to avoid traffic for a given 
the start and end? yes start of it is going to be an issue but the end of the 
major event can be at least conservative on not sending data? 
                
> Send Hints to Dynamic Snitch when Compaction or repair is going on for a node.

> 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.
