Unless you need a gastrointestinal consult, you probably don't want to ask "Bob Coli" a question... ;P Default compression is Snappy compression and I have seen compression ranging between 2-4% (just as the doc says). I got the storage part. Does it mean that as a result of compaction/repair SSTables are decompressed? Is it the reason for CPU utilization spiking up a little? Yes, compaction needs the values in SSTables, if those values are compressed it needs to decompress them. Yes, it one of the reasons compaction consumes noticable CPU. =Robhttp://twitter.com/rcolidba
