Subject Re: how do we updgrade cassandra
Date Sun, 19 Jul 2009 18:40:38 GMT
There's 'snapshot' functionality coming in https://issues.apache.org/jira/browse/CASSANDRA-279

  slated for 0.4, but to my knowledge no toolIng in the works for  
later using that data.  It should be as simple as tar'ing and  
restoring somewhere else after that.
