Subject Re: Issue with SizeTieredCompactionStrategy in 2.0.3
Date Fri, 13 Dec 2013 15:53:55 GMT
Hi Graham, thanks for reporting this.  I should be able to get it fixed

As far as how it's off by default, the default max_cold_reads_ratio is 0.0,
so filterColdSSTables() won't actually filter anything.  I can add a check
to skip that function if maxColdReadsRatio is 0.0 in the 6483 patch.
