Export to another cassandra cluster
I want to export data from one cassandra cluster (production) to
another (development). This is not a case of replication, because I
just want a snapshot, not a continuous synchronization. I guess my
options include 'nodetool snapshot' and 'sstable2json'. In our case,
however, the development cluster has 10 nodes whereas the production
cluster has 40. What's the recommended strategy for getting the data
in one column family from one cluster to the other?

I would lightly hack sstable2json to write rows to the other cluster,
instead of spitting them out as json. That would be a pretty simple
modification.
