Subject [jira] Updated: (CASSANDRA-1481) PropertyFileEndPointSnitch synchronization is a bottleneck
Date Thu, 14 Oct 2010 20:40:33 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-1481?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Ellis updated CASSANDRA-1481:
--------------------------------------

    Fix Version/s: 0.7.0

forward-ported to 0.7 in r1022690.  originally thought it was a non-issue in 0.7 because of
endpoint caching in Strategy, but getRack/getDatacenter are still called for each op by StorageProxy.
