Does this mean that LCS on 1.0.x should be considered unsafe to use? I'm using them for semi-wide frequently-updated CounterColumns and they're performing much better on LCS than on STCS. > In case you have old Leveled-compacted sstables (generated with 1.1.2 > or earlier. including 1.0.x) you need to run offline scrub using > Cassandra 1.1.4 or later via /bin/sstablescrub command so it'll fix > out-of-order sstables and inter-level overlaps caused by previous > versions of LCS. You need to take nodes down in order to run offline > scrub. The 1.1.5 README does not mention this. Should it? /Janne
