Subject Re: sstables remain after compaction
Date Tue, 03 Mar 2015 09:44:47 GMT
off topic for this discussion, and yea, we are in the midst of upgrading...
1.0.8 -> 1.0.12 then to 1.1.0.. then to the latest of 1.1.. then to 1.2.
keep my finger cross for safe upgrading for such a big cluster... we hope
that with cassandra moving some components off heap in 1.1 and 1.2, the
cluster would perform better, at least i do not need to do the user defined
compaction regulary.

thanks guys, jason
