Jonathan Ellis commented on CASSANDRA-1527:
-------------------------------------------
bq. Estimated compactions are the sum of all (1 + size_i / thresholdrange) for
i in SSTables with size > min
that looks buggy to me. doesn't estimate of
n += Math.ceil((double)sstables.size() / maxct);
make more sense?
bq. do we want to be estimating compactions when minor compactions are disabled
no
> ensure compaction thresholds are sane
