Subject [jira] [Updated] (CASSANDRA-3722) Send Hints to Dynamic Snitch when Compaction or repair is going on for a node.
Date Tue, 10 Jan 2012 22:16:39 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-3722?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vijay updated CASSANDRA-3722:
-----------------------------

    Description: 
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 causeing higher latencies.
