Subject Re: cassandra version update and my cluster
Date Thu, 02 Dec 2010 13:40:17 GMT
0.6->0.7 will require a full cluster restart.
0.7->0.8 will require a rolling restart, so long as CASSANDRA-1015 is completed.

keyspace/cf definitions will be readable across major versions, or
there will be a way provided to migrate them if that is not possible.

Gary.
