Subject [jira] [Created] (CASSANDRA-3321) Node joins/Node moves should build caches
Date Wed, 05 Oct 2011 20:38:29 GMT
Node joins/Node moves should build caches 

                 Key: CASSANDRA-3321
             Project: Cassandra
          Issue Type: New Feature
            Reporter: Edward Capriolo
            Priority: Minor

Cassandra use case: high rate of low latency reads served mostly from caches. When a new node
is joined data is streamed to it. However it is born into a 'cold world'. It does not have
the benefit of saved caches. Clients with auto-discovery will find it and start sending requests
it's way. If the request rate is high enough and clients are aggressive enough the Cassandra
node could run out of sockets. This feature would build 'best effort' caches possibly by sampling
entries from the caches of nodes the data was streamed from. With this even a newly joined
node should have cache warming.
