Vijay commented on CASSANDRA-3722:
----------------------------------
Another issue just came up which is related to this ticket.
Where a node just completed bootstrap and hence it will not have the files
cache warm enough for a faster response. Hence the scores for this node will be
much lower score and hence there is a very less traffic going to that node. The
problem is that unless there is more traffic sent the file caches will not warm
up fast enough. Should we T (send additional requests which are not part of the
normal operations) the requests until the other node recovers?
> Send Hints to Dynamic Snitch when Compaction or repair is going on for a node.

> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.1.0
> Reporter: Vijay
> Assignee: Vijay
> Priority: Minor
>
> 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.
