I'm I right that cfs keyspace lives only on analytics-mode nodes? If it's right, then what's the purpose of cfs? Temporary file system? There're nothing to write in this file system (I mean clients for different languages/frameworks/tool) but
dse hadoop fs and modeling file system in client application (inodes/sblocks etc) then write with cassandra client. And what with replication factor of this keyspace? Can it be changed?
