Vijay updated CASSANDRA-3722:
-----------------------------
Attachment: 0001-CASSANDRA-3722-A1.patch
Attached is the version which just has the hints and doesn't have pending queue
into the account. (Working on A2, just in case with artificial load for other
DC's).
Im addition there is a JMX, in which users can force load in/out into a node by
specifying +ve/-ve severity.
> 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.
