Hello everyone.
3 node Cassandra 0.8.5 cluster. I've left the system running in production
environment for long term testing. I've accumulated about 350GB of data
with RF=2. The machines I used for the tests are older and need to be
replaced. Because of this I need to export the data to a permanen

in CSV format, which makes it portable and we can load it into anything
if needed, or analyze on its own.
Just my half of a Swiss centime :)

Stop your current cluster. Start a new cassandra instance on the
machine you want to store your data on. Use the sstable loader to load
the sstables from all of the current machines into the new machine. Run
major compaction a couple times. You will have all of the data on one
machine.

Hi Jeremiah,
The thing is I will send the data to a massive storage facility (I don't
know what's behind the scenes) so I won't be backing up on one machine
where I can install Cassandra. Does the sstable loader work just for

Once you get all of the data on one machine you can then
flush/drain/compact shutdown the single node and then take the data
folder off that machine and back it up. Then when you get your new
cassandra cluster setup you can use the sstable loader to shoot the data
from the backup into the new
