Hudson commented on CASSANDRA-2175: ----------------------------------- Integrated in Cassandra-0.6 #60 (See [https://hudson.apache.org/hudson/job/Cassandra-0.6/60/]) make key cache preheating default to false patch by jbellis; reviewed by brandonwilliams for CASSANDRA-2175 > make key cache preheating use less memory > ----------------------------------------- > > Key: CASSANDRA-2175 > URL: https://issues.apache.org/jira/browse/CASSANDRA-2175 > Project: Cassandra > Issue Type: Improvement > Affects Versions: 0.6.9, 0.7.0 rc 3 > Reporter: Jonathan Ellis > Assignee: Jonathan Ellis > Priority: Minor > Fix For: 0.6.12, 0.7.3 > > Attachments: 2175-0.6.txt > > > CASSANDRA-1878 pre-heats the key cache post-compaction so latency doesn't > suffer while warming the cache back up. This can double the memory used > temporarily; for a large key cache, this can have a substantial impact. > For now a boolean on/off is probably the best we can do. With > http://code.google.com/p/concurrentlinkedhashmap/issues/detail?id=21 though, > we could say "preheat the hottest X keys." -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
