So you mean just the replica node 's sstable will be changed ,right? If all the replica node broke down, whether the users can read the data?

I > mean which way to know the actual data kept? If you're just doing testing, you might 'nodetool flush' each host and then look for the sstable being written. Prior to a flush, it's going to sit in a memtable in memory (and otherwise only in the commit log), up until the configurable time period. For real use-cases, you would normally not care which node has a particular row, except I suppose for debugging purposes or similar. I realize I don't know off hand of a simple way, from the perspective of the command line, to answer that question for a particular key. -- / Peter Schuller
