Is there any public information on the production installations you mention above? So far Googling/browsing we have mostly (only I think) seen production cases where the data has been possible to re-generate in the event of loss. As we are evaluating use of Cassandra for "important" data, we would be interested in hearing any success or failure stories. -- / Peter Schuller aka scode
